Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Locate the brake caliper and remove the caliper bolts with a socket.
3. Carefully lift the caliper off the rotor and hang it using a bungee cord (do not let it dangle by the brake line).
4. Remove the old brake pads from the caliper bracket.
5. Install new brake pads, ensuring proper orientation and fit.
6. Reinstall the caliper over the new pads and secure it with the caliper bolts, torquing to manufacturer specifications.

3. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. Remove the rotor from the hub by extracting any retaining screws.
2. Measure the rotor thickness; if below specifications, replace the rotor.
3. If the rotor is within specifications, use a brake lathe to resurface it, ensuring it is even and smooth.
4. Clean the rotor surface with brake cleaner before reinstalling.

4. Check and Adjust Wheel Alignment

Sub-steps:
1. Inspect alignment components (tie rods, control arms) for damage.
2. If components are intact, take the vehicle to a professional alignment shop.
3. Adjust alignment angles according to manufacturer specifications.
