Maintaining your Toyota Yaris’s braking system is crucial for its safety and performance. Changing brake fluid is a vital part of this maintenance routine, and it’s a task that you can easily perform yourself with the right tools and instructions. In this comprehensive guide, we’ll provide you with a step-by-step walkthrough of how to change brake fluid in your Toyota Yaris, ensuring a safe and efficient braking experience.
Understanding Brake Fluid
Brake fluid is a hydraulic fluid that transmits force from the master cylinder to the brake calipers, which in turn apply pressure to the brake pads. Over time, brake fluid can deteriorate due to moisture absorption and contamination, compromising its performance and the safety of your braking system.
Materials Required
Before getting started, gather the following materials:
- New DOT 3 brake fluid
- Brake fluid tester
- 10mm wrench or socket
- 8mm wrench or socket
- 1/4-inch drive ratchet
- Funnel
- Clean rags
- Gloves
Safety Precautions
- Wear gloves and eye protection throughout the process.
- Do not smoke or work near open flames.
- Brake fluid is corrosive, so avoid contact with your skin and eyes.
- Dispose of used brake fluid properly at a designated recycling facility.
Step-by-Step Instructions
1. Check Brake Fluid Level
Use the brake fluid tester to check the fluid level in the master cylinder reservoir. If the fluid level is low or below the “MIN” mark, it’s time to change the brake fluid.
2. Open Bleeder Valves
Locate the bleeder valves on the brake calipers. Use an 8mm wrench or socket to open the valves slightly, allowing air to escape.
3. Attach Funnel and Hose
Attach a funnel to the bleeder valve and insert a clear hose into the funnel. This hose will direct the old brake fluid into a container.
4. Pump Brake Pedal
Have an assistant pump the brake pedal slowly and firmly several times. Hold the pedal down on the final pump.
5. Open and Close Bleeder Valve
While the pedal is held down, slowly open the bleeder valve with the wrench or socket. Allow the old brake fluid to flow out through the hose until it’s clear of contaminants.
6. Close Bleeder Valve and Release Pedal
Once the fluid is clear, close the bleeder valve and release the brake pedal. Repeat steps 4-6 for each wheel, starting with the furthest wheel from the master cylinder.
7. Fill Master Cylinder Reservoir
Use a funnel to fill the master cylinder reservoir with new DOT 3 brake fluid. Do not overfill.
8. Test Brake System
Pump the brake pedal several times to build pressure. Check for any leaks or spongy pedal feel. If necessary, repeat the bleeding process.
Troubleshooting
- Spongy Pedal: Air is trapped in the system. Re-bleed all wheels.
- Leaking: Check all connections and tighten as needed.
- Low Fluid Level: Check for leaks and top up the fluid as necessary.
Maintenance Schedule
Change your brake fluid every 2 years or 30,000 miles, whichever comes first. Regular brake fluid changes will ensure optimal braking performance and prevent corrosion in the system.
In a nutshell: Maintaining a Safe Braking System
Changing brake fluid in your Toyota Yaris is a crucial maintenance task that you can easily perform yourself. By following the steps outlined in this guide, you can ensure that your vehicle’s braking system is operating at its best, providing you with peace of mind and safety on the road.
