Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface, engage the parking brake, and ensure the engine is off.
Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner.

2. Remove Wheel

Use the lug wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Jack up the vehicle and securely place it on jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the socket set and slide off the caliper.
Inspect the brake pads for wear; if the friction material is worn down to 3 mm or less, replace the pads.
Sub-steps:
- If replacing, compress the caliper piston using a brake tool or C-clamp to allow for new pads.
- Remove old pads and install new ones, ensuring they are seated properly.

4. Check and Resurface/Replace Rotors

Inspect the rotors for damage or excessive wear; if scored or warped, consider resurfacing or replacing them.
Sub-steps:
- If resurfacing, ensure the rotors are within manufacturer specifications.
- If replacing, remove the rotor bolts and install the new rotor securely.

5. Reassemble Brake Components

Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
