Solution

1. Preparation

Gather necessary tools and parts.
Ensure safety by parking on a flat surface and setting the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Loosen and remove the lug nuts using a socket set.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket set (torque specifications typically 18-25 ft-lbs).
Slide the caliper off the rotor and support it using a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pad backing for wear; if less than 3mm remaining, replace them.
Install new brake pads ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Rotors (if necessary)

Check the rotors for deep scoring or warping. If damaged, remove the rotor by unbolting it from the hub.
Clean the hub surface where the rotor mounts.
Install new rotors (if needed) and torque the rotor bolts to manufacturer specifications.

5. Reassemble Components

Reinstall the caliper over the new brake pads and rotor.
Tighten caliper bolts to specified torque.
Reattach the wheel and torque the lug nuts in a crisscross pattern to the specified torque.

6. Final Checks

Refill brake fluid if necessary, ensuring it’s at the recommended level.
Pump the brake pedal several times to seat the new pads against the rotor.
Lower the vehicle from the jack stands.
