Tools You'll Need:
* Brake fluid: Use DOT 3 or DOT 4 brake fluid, as specified in your owner's manual. *Never* use anything else.
* Bleeder wrench: Usually a 8mm or 10mm, but check your specific vehicle.
* Clear tubing: Long enough to reach a container.
* Container: To collect the old brake fluid.
* Wrench: To hold the caliper. An open-end or crescent wrench usually works best.
* Shop rags or paper towels: To clean up spills.
* Helper: It's much easier with two people.
Steps:
1. Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake firmly.
2. Locate Bleeder Valves: The bleeder valves are located on the top of each rear wheel caliper. They are small, usually have a hexagonal shape, and are designed to be opened with a bleeder wrench.
3. Fill the Master Cylinder: Check the master cylinder brake fluid reservoir. Top it off to the "full" line with fresh brake fluid. *It's crucial to keep the reservoir full during the bleeding process to prevent air from entering the system.*
4. Attach Tubing: Attach one end of the clear tubing to the bleeder valve. The other end should be submerged in your container.
5. Bleeding Procedure (Two-Person Job):
* One person sits in the driver's seat.
* The other person is at the wheel to be bled.
* IMPORTANT: Always bleed the furthest wheel from the master cylinder first (usually the right rear, then left rear). This helps push air towards the exit point.
* Have your helper slowly pump the brake pedal several times. *They should not pump the pedal rapidly or hold it down.*
* While your helper holds the pedal down, carefully open the bleeder valve with the bleeder wrench. You should see brake fluid flowing through the tube.
* Close the bleeder valve before your helper releases the brake pedal.
* Repeat steps 5 - 7 several times, until the fluid running through the tube is clear and free of bubbles.
* Top off the master cylinder reservoir as needed.
6. Repeat for other wheel: Repeat steps 5 for the other rear wheel.
7. Check Brake Pedal: After bleeding both rear wheels, have your helper pump the brake pedal several times. The pedal should feel firm. If it feels soft or spongy, you may have more air in the system and need to repeat the bleeding process.
8. Test Drive: After bleeding the brakes, perform a test drive in a safe, controlled environment. Pay close attention to the brake pedal feel and braking performance. If you're not satisfied with the result, consider seeking professional help.
Important Considerations:
* Brake Fluid is Corrosive: Brake fluid is corrosive. Clean up any spills immediately.
* Air in the Lines: If you can't get all the air out, you might have a more serious problem, such as a leak in the brake lines or a damaged master cylinder. Seek professional help in this case.
* Safety First: Brake bleeding is a potentially hazardous procedure. If you're not comfortable performing this task, take your vehicle to a qualified mechanic.
Remember, this is a general guide. Consult your owner's manual for specific instructions and torque specifications for your vehicle. Safety should always be your top priority.
