2018 Dodge Journey SXT Brake Bleeding Sequence Guide

Hey guys! If you've landed here, you're probably dealing with some brake issues on your 2018 Dodge Journey SXT, specifically after replacing a brake hose. Don't worry, we've all been there! Brakes are arguably the most critical safety system in your vehicle, so getting them right is super important. This guide will walk you through the proper brake bleeding sequence, ensuring your Journey's stopping power is top-notch.

Understanding Brake Bleeding

Before we dive into the specifics, let's quickly cover what brake bleeding actually is and why it's necessary. Brake bleeding is the process of removing air bubbles from your brake lines. Air in the brake lines can compress, unlike brake fluid, leading to a spongy brake pedal and reduced braking efficiency. This is because the air compresses instead of transmitting the pressure evenly throughout the brake system. When you press the brake pedal, you're essentially pushing hydraulic fluid through the brake lines to the calipers, which then clamp the brake pads against the rotors, slowing your car down. If there's air in the system, this process becomes less effective.

When you replace a brake hose, like you did on your 2018 Dodge Journey SXT, you introduce air into the system. Even small amounts of air can significantly impact your braking performance. That's why bleeding the brakes after any brake system repair is crucial. Moreover, brake fluid itself can absorb moisture over time, which can lead to corrosion and further compromise braking performance. Regular brake fluid flushes, which involve bleeding the entire system, are recommended every two to three years to maintain optimal brake health. So, whether you've replaced a component or just want to ensure peak performance, understanding the correct bleeding procedure is essential for any car owner. Ignoring this vital maintenance task can lead to serious safety issues, so let's get those brakes bled properly!

Do You Need to Bleed All Brake Lines?

Now, to answer your initial question: do you need to bleed all the lines or just the one you replaced? The general consensus, and what's highly recommended for safety, is that you should bleed all four brake lines whenever you open the brake system, especially if you've replaced a component like a brake hose. While it might seem like bleeding just the affected line would be sufficient, air bubbles can migrate through the system, potentially affecting other lines as well. Plus, bleeding all the lines ensures you're flushing out any old, contaminated fluid, further improving your braking performance. Think of it as a comprehensive health check for your brake system, ensuring every part is functioning optimally.

Even if you only opened one line, there's a chance air has been introduced elsewhere, especially if your brake fluid is old or the system hasn't been bled in a while. Bleeding all four lines provides peace of mind, knowing that you've eliminated any potential air pockets and restored your brakes to their full stopping power. This is particularly important on a vehicle like the Dodge Journey SXT, which is often used for family transport and requires reliable braking in various conditions. So, while it might seem like extra work, bleeding all four lines is the safest and most thorough approach, ensuring your brakes are ready to handle whatever the road throws your way. Always prioritize safety when it comes to your brakes, and a full bleed is a small price to pay for the confidence of a properly functioning system.

The Correct Brake Bleeding Sequence for Your 2018 Dodge Journey SXT

Okay, so we've established that bleeding all four lines is the way to go. Now, let's get into the correct brake bleeding sequence for your 2018 Dodge Journey SXT. The sequence is crucial because it ensures that you're effectively removing air from the entire system, starting with the brake furthest from the master cylinder and working your way closer. This method pushes the air out efficiently, preventing it from simply shifting to another part of the system. Skipping steps or bleeding in the wrong order can lead to trapped air and a continued spongy brake pedal.

For most vehicles, including your Journey, the standard bleeding sequence is as follows:

1. Right Rear (Passenger Side Rear): Start with the wheel furthest from the master cylinder.
2. Left Rear (Driver Side Rear): Move to the opposite rear wheel.
3. Right Front (Passenger Side Front): Then proceed to the front passenger side.
4. Left Front (Driver Side Front): Finish with the front driver side, which is usually the closest to the master cylinder.

This sequence is designed to systematically eliminate air from the longest brake lines to the shortest, ensuring a thorough bleed. Following this order is key to achieving a firm and responsive brake pedal. Remember, consistency is important, so stick to this sequence each time you bleed your brakes. Deviating from the sequence can result in an incomplete bleed, leaving air in the system and compromising your braking performance. So, whether you're a seasoned DIYer or a first-timer, adhering to this order will help you achieve the best results and keep your Dodge Journey SXT safely on the road.

Materials and Tools You'll Need

Before you jump into the brake bleeding process, let's make sure you have all the necessary materials and tools. Having everything on hand will make the job smoother and prevent any frustrating mid-task interruptions. Here’s a comprehensive list of what you’ll need:

• Brake Fluid: First and foremost, you’ll need the correct type of brake fluid for your 2018 Dodge Journey SXT. Consult your owner's manual to determine the specific type (usually DOT 3 or DOT 4). It's always best to use the manufacturer-recommended fluid to ensure compatibility and optimal performance. Buy enough fluid to completely flush the system – typically, 2-3 quarts should suffice. Using fresh, clean brake fluid is essential for proper brake function and longevity.
• Wrench: You'll need a wrench that fits your brake bleeder screws. The size can vary, but an 8mm or 10mm wrench is common. A flare nut wrench is highly recommended, as it provides a better grip and reduces the risk of rounding off the bleeder screw. A regular open-end wrench can slip and damage the screw, making future bleeds more difficult.
• Clear Tubing: A length of clear tubing (about 1/4 inch inner diameter) is necessary to attach to the bleeder screw and direct the fluid into a collection container. The clear tubing allows you to see the fluid as it exits the system, so you can visually confirm when the air bubbles are gone. This is a crucial step in ensuring a complete bleed.
• Collection Container: You'll need a container to collect the old brake fluid. An empty plastic bottle or jar works well. Make sure the container is clean to avoid contaminating the new brake fluid.
• Bleeder Bottle or Vacuum Bleeder (Optional): A bleeder bottle is a specialized container with a one-way valve that prevents air from being drawn back into the brake system. A vacuum bleeder is a tool that uses suction to draw the fluid through the lines, making the process faster and often easier, especially for solo bleeding. While not essential, these tools can significantly simplify the process.
• Jack and Jack Stands: You'll need a jack to lift your Journey and jack stands to safely support it. Never work under a vehicle supported only by a jack. Safety is paramount, so always use jack stands when working beneath your car.
• Wheel Chocks: Wheel chocks are an additional safety measure to prevent the vehicle from rolling while you're working on it. Place them behind the wheels that are staying on the ground.
• Gloves and Safety Glasses: Brake fluid can be corrosive and harmful to your skin and eyes, so wear gloves and safety glasses to protect yourself.
• Brake Parts Cleaner: This is useful for cleaning up any spilled brake fluid and for cleaning the bleeder screws before you start.
• Penetrating Oil: If your bleeder screws are rusty or corroded, penetrating oil can help loosen them. Apply it a few hours before you start the bleeding process.

With these materials and tools on hand, you'll be well-prepared to tackle the brake bleeding process on your 2018 Dodge Journey SXT. Remember, safety first – always use proper safety equipment and take your time to ensure the job is done correctly.

Step-by-Step Brake Bleeding Procedure

Alright, you've got your tools and materials ready, so let's dive into the step-by-step brake bleeding procedure for your 2018 Dodge Journey SXT. Follow these steps carefully to ensure a thorough and effective bleed. Remember, patience is key – take your time and double-check each step to avoid mistakes.

1. Prepare the Vehicle: Start by parking your Journey on a level surface, engaging the parking brake, and chocking the rear wheels. This will prevent the vehicle from rolling while you're working on it. Next, loosen the lug nuts on all four wheels. This makes it easier to remove the wheels once the car is lifted.
2. Lift and Secure the Vehicle: Use a jack to lift the vehicle and securely place jack stands under the frame. Never work under a vehicle supported only by a jack. Remove the wheels to access the brake calipers and bleeder screws.
3. Locate the Bleeder Screws: Identify the bleeder screws on the back of each brake caliper. They're typically small, bolt-like fittings with a rubber cap. Remove the rubber cap and inspect the bleeder screw for any signs of corrosion. If the screws are rusty or seized, apply penetrating oil and let it soak for a few hours before attempting to loosen them.
4. Prepare the Bleeding Setup: Attach one end of the clear tubing to the bleeder screw. Place the other end of the tubing into your collection container, ensuring the end of the tubing is submerged in brake fluid. This prevents air from being drawn back into the system during the bleeding process.
5. Bleed the First Brake (Right Rear): Using the correct size wrench (usually 8mm or 10mm), gently loosen the bleeder screw. Have a helper slowly press the brake pedal down. While the pedal is depressed, fluid and air bubbles will flow through the tubing into the container. Watch the fluid carefully – you'll see air bubbles initially. Once the flow of fluid is clear and free of bubbles, tighten the bleeder screw before your helper releases the brake pedal. This prevents air from being sucked back into the caliper. Repeat this process several times until no more air bubbles are visible.
6. Repeat for Remaining Brakes: Follow the correct bleeding sequence (Left Rear, Right Front, Left Front), repeating the same process for each brake. Remember to check the brake fluid level in the master cylinder reservoir frequently and top it off as needed. Never let the reservoir run dry, as this can introduce air into the entire system and require you to start the bleeding process all over again.
7. Final Check and Test: Once you've bled all four brakes, ensure the bleeder screws are snug (but not overtightened) and replace the rubber caps. Reinstall the wheels, torquing the lug nuts to the manufacturer's specification. Lower the vehicle and remove the jack stands. Before driving, pump the brake pedal several times to ensure it feels firm. Take your Journey for a test drive in a safe area to confirm that the brakes are functioning correctly. The brake pedal should feel firm and responsive, and the car should stop smoothly and evenly.

By following these steps carefully, you can effectively bleed your 2018 Dodge Journey SXT's brakes and restore its stopping power. If you're unsure about any part of the process, don't hesitate to consult a professional mechanic. Remember, brake safety is paramount, so it's always better to be cautious and seek expert advice when needed.

Troubleshooting Common Issues

Even with the best instructions, sometimes things don't go exactly as planned. Let's talk about some common issues you might encounter while bleeding your brakes and how to troubleshoot them. Knowing how to address these problems can save you time and frustration.

• Rounded Bleeder Screw: One of the most common headaches is a rounded bleeder screw. This happens when the wrench slips and damages the corners of the screw, making it difficult to get a grip. To prevent this, always use a flare nut wrench, which provides a better hold on the screw. If you've already rounded a bleeder screw, try using a specialized bleeder screw removal tool or a pair of locking pliers. If all else fails, you may need to replace the caliper. Prevention is key here, so take your time and use the right tools.
• Seized Bleeder Screw: Another frequent issue is a bleeder screw that's seized due to rust and corrosion. Before attempting to loosen it, apply penetrating oil and let it soak for several hours, or even overnight. Gently tap the screw with a hammer to help the oil penetrate. If it's still stuck, try applying heat with a heat gun or propane torch (be careful not to damage any surrounding components). If the screw remains seized, you may need to replace the caliper. Regular brake maintenance can help prevent this issue.
• Spongy Brake Pedal After Bleeding: If you've bled the brakes but the pedal still feels spongy, there's likely still air in the system. Double-check your bleeding procedure and ensure you followed the correct sequence. Make sure the bleeder screw is tightened before releasing the brake pedal to prevent air from being sucked back in. Also, check for any leaks in the brake lines or connections. If the problem persists, you may have an issue with the master cylinder or ABS system, which may require professional diagnosis.
• Master Cylinder Running Dry: Allowing the master cylinder to run dry while bleeding the brakes can introduce air into the entire system, making the bleeding process much more difficult. Keep a close eye on the fluid level in the reservoir and top it off frequently. If the master cylinder does run dry, you'll need to bleed the entire system again, starting with the master cylinder itself.
• Leaking Brake Fluid: If you notice brake fluid leaking from any connections or the master cylinder, address the issue immediately. Leaks can compromise your braking performance and pose a safety hazard. Check the brake lines, hoses, and caliper connections for any signs of damage or corrosion. Replace any damaged components and re-bleed the brakes.

By being aware of these potential issues and knowing how to troubleshoot them, you can confidently tackle your 2018 Dodge Journey SXT brake bleeding process. Remember, if you're ever unsure or encounter a problem you can't resolve, it's always best to consult a qualified mechanic. Your safety is the top priority!
