Key Takeaways
- Importance of Brake Bleeding: Removing air from brake lines is crucial for maintaining optimal braking performance and safety.
- Two Methods Available: You can bleed your brakes manually or by using a vacuum pump. We’ll cover both methods step-by-step so you can choose the best one for you.
- Safety First: Always prioritize safety by wearing protective gear, securing your vehicle properly, and following manufacturer guidelines.
- Detailed Steps Provided: Follow our concise, step-by-step instructions for a successful brake bleeding process.
- Regular Maintenance Matters: Bleeding your brakes regularly extends the life of your brake system and ensures your ATV or UTV performs safely.
Bleeding Your Brakes is Essential
Over time, air can enter your UTV or ATVs brake system, leading to decreased braking efficiency and a spongy brake feel. Bleeding the brakes removes trapped air and replaces old brake fluid, ensuring your vehicle’s brakes are responsive and effective. This is crucial for:
- Safety: Reliable brakes are essential for safe riding.
- Performance: Optimal braking improves control and handling.
- Maintenance: Regular bleeding extends the life of your brake components.
Safety Precautions
Before starting, prioritize safety:
- Consult the Owner’s Manual: Check for specific instructions and recommended brake fluid type for your vehicle.
- Wear Protective Gear:
- Gloves: To protect your skin from corrosive brake fluid.
- Safety Goggles: To shield your eyes from splashes.
- Secure the Vehicle Properly:
- Use a jack and jack stands to lift and stabilize your vehicle.
- Never rely solely on a jack.
- Work in a Well-Ventilated Area: Brake fluid fumes can be harmful.
- Handle Brake Fluid Carefully:
- Avoid spilling on paint or plastics; it can cause damage.
- Clean up spills immediately.
- Environmental Responsibility: Dispose of used brake fluid at an authorized recycling center.

Preparing Your Vehicle
- Park on a Level Surface: Ensure stability.
- Engage Parking Brake: Prevents movement.
- Gather Tools and Materials: Have everything within reach.
- Lift the Vehicle:
- Use the jack to lift your ATV or UTV.
- Secure with jack stands under proper points.
- Remove the Wheels:
- Loosen lug nuts with the lug wrench.
- Remove wheels carefully and set aside.
- Locate the Brake Fluid Reservoir:
- ATVs: Typically near the handlebar.
- UTVs: Often near the driver’s seat.
- Clean Around Reservoir Cap:
- Prevents contamination when opened.
Method 1: Manual Brake Bleeding
Manual bleeding is a traditional and effective method but usually requires a helper, previously mentioned on our powersports blog.
Manual Bleeding Step-by-Step Guide
Step 1: Prepare the Brake Fluid Reservoir
- Remove the reservoir cap and diaphragm.
- Clean them with a clean rag.
- Top off with fresh brake fluid to the “MAX” line.
Step 2: Attach Clear Tubing
- Start with the caliper farthest from the master cylinder (usually rear right).
- Place one end of the tubing over the bleeder valve.
- Submerge the other end in a container partially filled with brake fluid.
Step 3: Pump and Hold the Brake
- Have your helper pump the brake lever/pedal several times.
- They should then hold it down firmly.
Step 4: Open the Bleeder Valve
- Use the appropriate wrench to open the valve about a quarter turn.
- Fluid and air bubbles will flow through the tubing.
Step 5: Close the Bleeder Valve
- Before the brake lever/pedal reaches the end of its travel, tighten the valve.
- Instruct your helper to slowly release the brake.
Step 6: Repeat Until No Air Bubbles
- Continue steps 3–5 until fluid flows without air bubbles.
- Keep the reservoir topped off to prevent air from entering.
Step 7: Move to Next Caliper
- Proceed to the next farthest caliper.
- Repeat the bleeding process for each wheel.
Step 8: Finalize
- After all calipers are bled, ensure the reservoir is filled.
- Replace the diaphragm and cap securely.
Method 2: Vacuum Brake Bleeding
Vacuum bleeding allows for one-person operation and is efficient with the right equipment.
Vacuum Bleeding Step-by-Step Guide
Step 1: Set Up the Vacuum Pump
- Attach the pump’s hose to the bleeder valve on the farthest caliper.
- Ensure all connections are airtight.
Step 2: Prepare the Brake Fluid Reservoir
- Remove the cap and diaphragm.
- Clean and top off with brake fluid.
Step 3: Create Vacuum
- Operate the pump to create negative pressure.
Step 4: Open the Bleeder Valve
- Slowly open the valve while maintaining vacuum.
- Fluid and air will be drawn into the pump’s reservoir.
Step 5: Monitor Fluid and Air
- Continue until fluid flows without air bubbles.
- Keep an eye on the brake fluid level in the reservoir.
Step 6: Close the Bleeder Valve
- Tighten the valve while maintaining vacuum.
- Release the vacuum pressure.
Step 7: Repeat for Each Caliper
- Move to the next caliper, following the correct sequence.
- Repeat steps 3–6.
Step 8: Finalize
- Ensure the reservoir is filled to the proper level.
- Replace the diaphragm and cap.
Post-Bleeding Procedures
- Check for Leaks:
- Inspect all bleeder valves and connections.
- Test Brake Feel:
- Press the brake lever/pedal; it should feel firm.
- If spongy, repeat the bleeding process.
- Reinstall Wheels:
- Place wheels back on.
- Hand-tighten lug nuts.
- Lower the Vehicle:
- Remove jack stands carefully.
- Lower the vehicle with the jack.
- Torque Lug Nuts:
- Tighten according to manufacturer specs.
- Clean Up:
- Wipe any spilled brake fluid.
- Dispose of old fluid responsibly.
Troubleshooting Common Issues
- Spongy Brakes Persist:
- Air may still be in the system.
- Repeat bleeding, ensuring no air enters the reservoir.
- Brake Fluid Level Drops Quickly:
- Check for leaks in lines and connections.
- Difficulty Building Pressure:
- Ensure all bleeder valves are closed properly.
- Inspect the master cylinder for issues.
- Brake Fluid Appears Dirty:
- Consider a full brake system flush.
Maintenance Tips for Long-Lasting Brakes
- Regular Inspection:
- Check pads, rotors, and lines for wear or damage.
- Annual Bleeding:
- Bleed brakes at least once a year.
- Use Correct Brake Fluid:
- Always use the type specified in your manual.
- Keep Components Clean:
- Remove dirt and debris from brake parts.
- Monitor Fluid Levels:
- Check the reservoir regularly.

Frequently Asked Questions
How often should I bleed my ATV or UTV brakes?
At least once a year or whenever you notice decreased braking performance.
Can I bleed the brakes by myself?
Yes, using a vacuum pump allows for solo bleeding. The manual method typically requires a helper.
* Safety Reminder: Never compromise on safety. If you’re unsure about any step, consult a professional mechanic.
What type of brake fluid should I use?
Use the brake fluid type specified in your owner’s manual (usually DOT 3 or DOT 4). Use the specific type recommended for your vehicle model because different fluids have varying properties and using the wrong one could damage your brake system.
* Environmental Tip: Always dispose of used brake fluid responsibly. Check local regulations for proper disposal methods.
Is discolored brake fluid a problem?
Yes, dark or dirty fluid indicates contamination. Consider flushing the system.
Why Should Bleed Tubes Be Submerged in Fluid During Brake Bleeding?
Submerging the end of the bleed tube in brake fluid prevents air from being drawn back into the brake system when the brake lever or pedal is released. The submerged fluid creates a one-way barrier, allowing air and old brake fluid to exit through the tube while stopping air from re-entering the brake lines. This ensures that only brake fluid, not air, is pulled back into the system, making the bleeding process effective in removing all trapped air and restoring proper brake function.
What if my brakes still feel spongy after bleeding?
Air may still be in the system, or there may be a leak. Recheck all connections and repeat the bleeding process.
How to Bleed ATV and Side by Side Brakes Manually:
