Tools and Materials Needed:
- Brake fluid (as recommended by your vehicle's manufacturer)
- Brake bleeder wrench
- Clear tubing (at least 2 feet long)
- Wrench or socket set
- Safety goggles
Step 1: Prepare the Vehicle:
- Park your car on level ground and turn off the engine.
- Engage the parking brake.
- Make sure the brake fluid reservoir is full. If it's low, add brake fluid until it reaches the "MAX" or "FULL" mark.
Step 2: Locate the Bleeder Screws:
- The bleeder screws are usually located on the brake calipers near the wheels. They are typically small and are often protected by a rubber cap.
Step 3: Connect the Bleeder Hose:
- Attach one end of the clear tubing to the bleeder screw. Make sure the tubing fits snugly to prevent air from leaking.
- Submerge the other end of the tubing in a clear container partially filled with brake fluid.
Step 4: Open the Bleeder Screw:
- Use the brake bleeder wrench to loosen and open the bleeder screw about 1/4 to 1/2 turn.
Step 5: Pump the Brake Pedal:
- Have a helper slowly press down on the brake pedal until it feels firm. This forces the old brake fluid and any trapped air out of the system.
Step 6: Watch for Bubbles:
- As the brake pedal is depressed, you should see bubbles rising in the clear container of brake fluid. This indicates that the air is being expelled from the system.
Step 7: Close the Bleeder Screw:
- Once the flow of bubbles stops or significantly reduces, have your helper hold the brake pedal down while you tighten the bleeder screw. This prevents air from being drawn back into the system.
Step 8: Repeat the Process:
- Repeat steps 4 to 7 until no more bubbles are visible when the brake pedal is pressed.
Step 9: Repeat for Other Wheels:
- Move on to the next front brake caliper and repeat the process to bleed the other front brake line.
Step 10: Check Brake Fluid Level:
- After bleeding the brakes, check the brake fluid reservoir again. If the level has dropped, add brake fluid until it reaches the recommended level.
Step 11: Test the Brakes:
- Pump the brake pedal a few times to build up pressure in the brake system. The pedal should feel firm and not spongy.
Step 12: Clean Up:
- Remove the bleeder hose and clean any spilled brake fluid from the vehicle.
Remember, bleeding brakes can be messy and brake fluid can irritate skin and eyes, so wear protective gear and handle brake fluid with care. If you're not confident in your ability to perform this task, it's best to consult a professional mechanic.
