Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.
Safety Warnings: Ensure vehicle is securely supported before working underneath; wear safety glasses to protect from debris.

2. Remove the Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads from the caliper bracket.
- Compare the thickness of brake pads and replace if uneven wear is evident.
- Installation: Apply brake grease to the backing of the new pads, install them in the caliper bracket, and reattach the caliper.
Brake Rotors:
- Inspect the rotors for warping or scoring.
- If necessary, replace the rotor by removing the caliper bracket and rotor from the hub.
- Install new rotors, ensuring they are properly seated.

4. Caliper and Suspension Check

Inspect caliper pistons for smooth operation; replace calipers if sticking.
Check suspension components such as bushings and tie rods for wear, and replace as needed.

5. Reassembly

Reattach the caliper and torque the bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).
Reinstall the wheel, hand-tightening the lug nuts first, then lower the vehicle and torque lug nuts to specifications (usually around 80-90 ft-lbs).
