Solution

1. Preparation

Gather tools and parts required.
Lift the vehicle using a hydraulic jack and secure it on jack stands.
Remove the wheel to access brake components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Slide the caliper off the rotor and support it with a bungee cord to avoid strain on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper bracket for damage and clean it if necessary.
5. Install new brake pads in the caliper bracket.
Tools Required: Socket set, bungee cord, brake cleaner.

3. Inspect and Resurface or Replace Brake Rotors

Sub-steps:
1. Measure rotor thickness to ensure it meets specifications using a micrometer.
2. If warped, either resurface the rotors using a brake lathe or replace them with new rotors.
3. If resurfacing, ensure the surface is smooth and free from grooves.
4. Clean the rotors with brake cleaner before reinstalling.
Tools Required: Micrometer, brake lathe (if resurfacing), brake cleaner.

4. Reassemble Components

Sub-steps:
1. Reinstall the caliper over the new brake pads.
2. Torque caliper bolts to the manufacturer's specifications (usually around 20-30 ft-lbs).
3. Reinstall the wheel and torque lug nuts to the manufacturer's specifications.
Tools Required: Torque wrench.

5. Brake Fluid Check

Sub-steps:
1. Check the brake fluid reservoir and top off with the recommended fluid (DOT 3 or DOT 4).
2. Bleed the brakes if necessary to remove air from the system.
Tools Required: Brake fluid, brake bleeder kit.
