Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety during the repair.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Jack up the vehicle and securely place it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads

Remove the caliper bolts using a socket set.
Detach the caliper and hang it using a bungee cord (do not let it hang from the brake line).
Remove old brake pads and inspect for uneven wear.
Install new brake pads ensuring they are properly aligned.

Brake Rotors

Inspect the rotors for warping using a dial indicator.
If warped, remove the rotors by unscrewing the retaining screws and sliding them off the hub.
Install new rotors or have them resurfaced if they meet the minimum thickness specifications.

Brake Calipers

Check for caliper functionality; if they are sticking, consider rebuilding or replacing the caliper.
Ensure caliper slides are lubricated.

4. Reassemble Components

Reattach the caliper over the new brake pads and torque the caliper bolts to the manufacturer's specifications (typically around 25-35 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value (usually 80-100 lb-ft).

5. Final Checks

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