Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel Assembly

Use a jack to lift the vehicle and secure with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Components

3.1 Brake Pads

Remove the caliper bolts using a socket set.
Slide the caliper off the brake rotor and support it with a bungee cord (do not hang it from the brake line).
Remove old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly aligned.

3.2 Brake Rotors

If the rotors are damaged, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Clean the hub surface with a wire brush.
Install new rotors, ensuring they are seated properly.

3.3 Reassemble Caliper

Compress the caliper piston using a brake caliper tool to allow room for the new pads.
Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).

4. Reassemble Wheel and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification (usually 100-120 ft-lbs).

5. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper brake function before driving.
