[How to Fix] ATV Brake Won’t Build Pressure

If you’ve landed on this post, it’s probably because you’re dealing with an ATV brake system that won’t build pressure. As someone with over 20 years of experience in the mechanics world, I’d say that this is an issue you don’t want to ignore.

Brakes are the linchpin of your all-terrain vehicle’s safety, and if they’re not working correctly, you’re putting yourself at significant risk.

So, what does it mean when your ATV brakes won’t build pressure? In simple terms, you’ll notice that the brake pedal feels soft or spongy, and it might even go all the way to the floor when you press down on it. In the worst-case scenario, your ATV might not stop at all. Sounds like a nightmare, doesn’t it?

Don’t worry, though; you’re in good hands. In today’s post, we’re going to walk through the symptoms of a brake system failing to build pressure, the most likely culprits behind this issue, and a step-by-step guide on how to fix it. Let’s go!

Symptoms of ATV Brakes Failing to Build Pressure

Knowing what to look for is half the battle. If you suspect your ATV brakes are having trouble building pressure, there are some unmistakable signs that should set off alarm bells. Here are a few symptoms to keep an eye out for:

1. Soft or Spongy Brake Pedal

If you notice that the brake pedal feels softer than usual or has a spongy texture when you press it down, that’s a red flag. You should be able to feel a firm resistance when pressing the brake pedal; if you don’t, it’s time for some investigative work.

2. Pedal Goes All the Way to the Floor

In extreme cases, the brake pedal might sink all the way to the floor when you apply pressure. If this happens, your braking system is severely compromised, and you should address it immediately.

3. Reduced Stopping Power

If you feel that your ATV isn’t coming to a stop as quickly as it used to, or if you have to press down harder to get the vehicle to stop, that’s another indication that the brakes aren’t building sufficient pressure.

4. Warning Lights

Your ATV may have a warning light on the dashboard indicating a problem with the braking system. While a warning light could signify various issues, when paired with any of the above symptoms, it likely points to a brake pressure problem.

Tools and Supplies Needed

Before you dive into fixing your ATV’s brake system, you’ll want to make sure you have all the essential tools and supplies at hand. Here’s a list of what you’ll need:

1. Basic Tools

  1. Wrench set: You’ll need this for loosening and tightening various bolts and nuts.
  2. Screwdrivers: A set of flat-head and Phillips screwdrivers will come in handy.
  3. Pliers: Useful for gripping small parts.

2. Specialized Tools

  1. Brake Bleeder Kit: This will help you bleed the air out of the brake lines.
  2. Brake Fluid Tester: Optional but useful to test the quality of the existing brake fluid.

3. Consumables

  1. Brake Fluid: Always good to have extra; make sure it meets your ATV’s specifications.
  2. Shop Towels: For cleaning up spills and wiping down parts.
  3. Gloves: To protect your hands from brake fluid and other chemicals.

Step-by-Step Guide to Fixing ATV Brakes

The following is the step-by-step guide on how to fix ATV brakes;

1. Safety First

Before you start, make sure you’re in a well-ventilated area, preferably a garage or an outdoor space. Put on your gloves and safety glasses to protect yourself from brake fluid and other debris.

2. Inspecting the Brake System

Use a flashlight to look over your brake lines, master cylinder, and brake pads. Take note of any visible damage or leaks.

3. Bleeding the Brake Lines

  1. Attach the brake bleeder kit to the bleeder valve located on the brake caliper.
  2. Have someone press the brake pedal while you open the valve to release air bubbles. Close the valve before the pedal is fully depressed.
  3. Repeat until no more air bubbles come out.

    4. Replacing Brake Pads

    1. Remove the caliper bolts and slide the caliper off the rotor.
    2. Take out the old brake pads and replace them with the new ones.
    3. Reattach the caliper and tighten the bolts securely.

    5. Checking for Fluid Leaks

    1. Inspect the brake fluid reservoir, lines, and connections for any signs of leakage.
    2. Tighten any loose connections and replace damaged parts as needed.

    6. Testing the Master Cylinder

    Press down on the brake pedal and release. If the pedal sinks slowly or doesn’t rise back up quickly, the master cylinder likely needs to be replaced.

    7. Pressure Testing

    1. After making the necessary fixes, go for a test ride in a safe, controlled environment.
    2. Pay close attention to the brake pedal’s feel and stopping power. If you notice any of the symptoms you started with, you may need to revisit your repairs.

    Frequently Asked Questions

    Why is my brake pedal still spongy after bleeding the brakes?

    There may still be air in the lines, or the master cylinder could be failing. You may need to bleed the brakes again or consider replacing the master cylinder.

    Can I use any brake fluid?

    Always refer to your ATV’s manual for the specific type of brake fluid that’s compatible with your system. Using the wrong type can lead to reduced performance or even damage.

    How often should I check my ATV’s brake system?

    A general rule of thumb is to inspect your brake system thoroughly at least once a year, but more often if you ride your ATV regularly or in extreme conditions.

    Is it safe to test my fixes on an open trail?

    It’s best to test your brake repairs in a controlled environment first, like an empty parking lot, before hitting the trails again.

    What if I’m not comfortable performing these repairs myself?

    If you’re unsure about any steps or simply don’t feel confident, it’s always better to seek professional help. A certified mechanic can correctly diagnose and fix the problem.

    Final Thoughts

    Remember, your safety is paramount, and your braking system is not something to take lightly. Always take the time to perform regular checks and maintenance to ensure your rides are both fun and safe.
