Solution

1. Preparation

Tools Required: Brake cleaner, jack and jack stands, lug wrench, torque wrench, and safety glasses.
Lift the vehicle using the jack and secure it with jack stands.
Remove the wheels using the lug wrench.

2. Inspect Brake Components

Sub-steps:
1. Remove the brake caliper by unscrewing the mounting bolts with a socket set.
2. Carefully slide the caliper off the brake pads and hang it using a bungee cord (do not let it hang by the brake line).
3. Inspect the brake pads for uneven wear or glazing. Replace if worn below manufacturer specifications (typically 3mm).
4. Inspect the brake rotors for scoring or warping. If warped, resurface or replace as needed.

3. Clean and Lubricate

Sub-steps:
1. Clean the brake pads and caliper bracket with brake cleaner to remove dust and debris.
2. Apply a thin layer of brake grease on the back of the brake pads to reduce noise.
3. Lubricate the sliding pins of the caliper with high-temperature brake grease.

4. Reassemble and Test

Sub-steps:
1. Reattach the brake caliper and torque the mounting bolts to manufacturer specifications (typically 20-30 ft-lbs).
2. Reinstall the wheel and lug nuts, torquing them to specifications (typically 76 ft-lbs).
3. Lower the vehicle and pump the brake pedal to seat the pads before test driving.
