Solution

1. Preparation

Gather tools and parts required for the repair.
Safely lift and secure the vehicle on jack stands.
Wear safety gloves and goggles.

2. Remove Wheel Assembly

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket and ratchet.
Gently slide the caliper off the rotor and support it without stressing the brake line.
Remove the old brake pads and inspect the caliper for damage.
Install new brake pads that meet OEM specifications, ensuring proper alignment.

4. Inspect and Replace Brake Rotors

Remove the rotor from the hub if warped or damaged.
If replacing, install the new rotor, ensuring it is seated properly.
Torque the rotor to manufacturer specifications (typically 60-80 ft-lbs).

5. Reassemble and Bleed Brake System

Reattach the caliper over the new brake pads and torque caliper bolts.
Replace the wheel and torque lug nuts to manufacturer specifications (typically 100-150 ft-lbs).
Bleed the brake system to remove air from the lines using a brake bleeder kit.
