Tools You Will Likely Need:
* Wheel chocks: Essential for safety.
* Jack and jack stands: Never work under a car supported only by a jack.
* Lug wrench: To remove the wheels.
* Socket wrench set: Various sizes, including metric.
* Brake caliper piston compressor tool: To compress the brake caliper piston. This is crucial to allow you to install the new wheel cylinder.
* Wheel cylinder installer/remover: Makes the job much easier. May be able to rent it from an auto parts store.
* Wrench for brake lines: Usually a flare nut wrench or line wrench.
* New rear wheel cylinder: Make sure to get the correct one for your Malibu.
* Brake fluid: DOT 3 or DOT 4, as specified in your owner's manual.
* Clean rags or shop towels: To clean up brake fluid spills.
* Gloves: To protect your hands from brake fluid and grease.
* Safety glasses: To protect your eyes.
General Steps (Consult your repair manual for precise details):
1. Safety First: Chock the front wheels, engage the parking brake, and use jack stands to securely lift the rear of the vehicle. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Disconnect the Brake Line: Carefully disconnect the brake line from the old wheel cylinder. Have a container ready to catch any spilled brake fluid. You'll likely need a flare nut wrench to avoid damaging the fittings.
4. Remove the Old Wheel Cylinder: Use the wheel cylinder installer/remover tool to carefully remove the old wheel cylinder. This can be tricky, and a worn cylinder can be difficult to remove. Take your time and be patient.
5. Clean the Brake Drum (if applicable): Thoroughly clean the brake drum or rotor and the area where the new cylinder will install.
6. Install the New Wheel Cylinder: Using the installer tool, carefully install the new wheel cylinder. Make sure it's fully seated.
7. Reconnect the Brake Line: Carefully reconnect the brake line to the new wheel cylinder. Tighten it securely, but don't overtighten.
8. Bleed the Brakes: This is crucial to remove any air from the brake lines. You'll need a helper to pump the brake pedal while you open and close the bleeder valve on the caliper. Refer to your repair manual for the correct bleeding procedure.
9. Reassemble: Reinstall the wheel and lug nuts, and lower the vehicle.
10. Test the Brakes: After bleeding the brakes, carefully test them. If anything feels unusual, do not drive the vehicle.
Important Considerations:
* Brake Fluid is Corrosive: Brake fluid is corrosive and can damage paint and other materials. Clean up any spills immediately.
* Proper Bleeding is Crucial: Air in the brake lines can lead to brake failure. Make sure you bleed the brakes correctly.
* Professional Help: If you're not comfortable performing this repair, take your vehicle to a qualified mechanic. Brake repair is extremely important for safety.
This is a simplified overview. Always consult a repair manual specific to your 2000 Chevy Malibu before attempting this repair. Incorrectly performed brake work can be extremely dangerous. If in doubt, seek professional help.
