Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and securely lifted.
Disconnect the battery to avoid any electrical hazards.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Remove the brake caliper by unscrewing the caliper bolts; support it with a bungee cord to avoid strain on the brake line.
3. Remove the brake pads from the caliper bracket.
4. Use a dial indicator to measure rotor runout; replace if warped beyond manufacturer specifications (typically more than 0.002 inches).
5. If necessary, remove the rotor by unscrewing the retaining screws or using a hammer to break it loose.
6. Install new rotors, ensuring to clean the rotor surfaces with brake cleaner to remove any protective oil.

3. Replace Brake Pads

Sub-steps:
1. Install new brake pads into the caliper bracket, ensuring they are oriented correctly.
2. Compress the caliper piston using a C-clamp or brake caliper tool to allow for the new pads’ thickness.
3. Reattach the brake caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications.

4. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
3. Reconnect the battery and pump the brake pedal to ensure proper caliper engagement before driving.
