Solution

1. Preparation

Gather tools and parts needed for the repair.
Safety equipment: gloves and safety glasses.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle with a jack and secure it with jack stands.
3. Remove the lug nuts completely and take the wheel off.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and hang it using a wire or bungee cord (do not let it dangle).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pads for wear; replace if less than 3mm thickness remains.
5. Install new brake pads, ensuring they are seated properly.

4. Inspect and Resurface/Replace Rotors

Sub-steps:
1. Check the rotor surface; if it is scored or warped, replace or resurface it.
2. If replacing, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
3. Install the new rotor and torque the retaining screws to the manufacturer’s specifications.

5. Reassemble Braking System

Sub-steps:
1. Reinstall the caliper over the new brake pads and rotor.
2. Tighten caliper bolts to the manufacturer’s torque specifications.
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle to the ground and fully tighten the lug nuts in a crisscross pattern.
