Solution

1. Preparation

Gather tools and materials required for the repair.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery.

2. Inspect and Replace Brake Components

Brake Pads:
1. Remove the wheel using a socket set.
2. Remove the caliper bolts and lift the caliper away from the rotor.
3. Inspect the brake pads for wear; replace if worn below manufacturer specifications.
4. Install new brake pads in the caliper bracket.
Brake Rotors:
1. If rotors are warped, remove the caliper bracket.
2. Remove the rotor from the hub by unscrewing any retaining screws and sliding it off.
3. Clean the hub surface and install new rotors, ensuring they are properly seated.
4. Torque the rotor retaining screws to the manufacturer's specifications.

3. Wheel Alignment and Balance

After replacing brake components, have the wheel alignment checked.
Ensure tires are balanced properly to prevent vibrations.

4. Final Assembly

Reinstall the caliper bracket and torque bolts to specifications.
Reinstall the wheel and torque lug nuts in a star pattern.
Reconnect the battery.

5. Brake System Bleeding (if necessary)

If brake fluid was replaced or the system opened, bleed the brakes using a brake bleeder kit.
Ensure there are no air bubbles in the brake lines.

Tools Required:

Socket set
Torque wrench
Brake bleeder kit
Dial indicator (for rotor runout test)
Screwdriver set

Parts Required:

Brake pads
Brake rotors
Brake fluid (if necessary)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Disconnect the battery before working on the braking system.
