Tools You'll Likely Need:
* Jack and jack stands (essential for safety!)
* Wheel chocks
* Lug wrench
* Socket wrench set (metric)
* Brake caliper removal tool (sometimes called a C-clamp or piston compressor)
* Torque wrench
* Wire brush
* Brake cleaner
* New brake pads and shoes (or rotors if needed)
* Gloves
* Safety glasses
Steps:
1. Safety First: Park on a level surface, engage the parking brake firmly, and chock the front wheels. Raise the rear of the vehicle using the jack and securely support it with jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Inspect the Brakes: Carefully inspect the brake pads, shoes (if applicable - drum brakes are less common on 626's, but possible on older models), and rotors (if applicable) for wear and tear. Note the condition of the brake lines and calipers.
4. Drum Brakes (If Applicable):
* Remove the Drum: You may need to use a drum puller to remove the brake drum.
* Inspect the Shoes: Check the brake shoes for wear and tear. Replace if necessary.
* Adjust the Self-Adjusters: Most drum brakes have self-adjusting mechanisms. You might need to adjust them according to your manual. This is crucial for proper braking.
* Reassemble: Carefully reinstall the brake shoes, springs, and drum.
5. Disc Brakes (More Likely on Later Models):
* Remove the Caliper: Use the caliper removal tool to compress the caliper piston. This allows you to remove the caliper. You may need to carefully loosen the caliper mounting bolts before compressing the piston. Support the caliper with a wire or bungee cord to keep it from dangling.
* Remove the Pads: Remove the old brake pads.
* Inspect the Rotors: Inspect the brake rotors for wear, scoring, or excessive rust. Replace if necessary.
* Install New Pads: Install the new brake pads, ensuring they are properly seated.
* Reinstall the Caliper: Reinstall the caliper, making sure the caliper mounting bolts are properly tightened to the manufacturer's specifications (use a torque wrench).
6. Reassemble: Reinstall the wheel and tighten the lug nuts to the manufacturer's specified torque.
7. Lower the Vehicle: Carefully lower the vehicle.
8. Test the Brakes: Test the brakes thoroughly in a safe, open area before driving the vehicle. You should notice a firm brake pedal and responsive braking.
Important Considerations:
* Bleeding the Brakes: If you've separated any brake lines, you'll need to bleed the brakes to remove air from the system. This is crucial for safe operation.
* Torque Specifications: Always refer to your vehicle's repair manual for the correct torque specifications for all bolts and nuts. Over-tightening can damage components, while under-tightening can lead to loosening and failure.
* Brake Fluid: If you're working on the brake lines or bleed the system, be prepared to top off your brake fluid reservoir.
* Professional Help: If you are unsure about any part of this process, it is best to seek professional help from a qualified mechanic. Brake systems are critical for safety; improper repair can have serious consequences.
This information is for guidance only. Consult your vehicle's repair manual for specific instructions and safety precautions. Improper brake repair can be dangerous. If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic.
