Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and glasses.

2. Remove Wheel

Loosen the lug nuts using a socket set.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspection: Use a dial indicator to measure rotor runout; if out of specifications, replace.
Replacement:
1. Remove caliper bolts with a socket set and detach the caliper from the rotor.
2. Support the caliper with a wire hanger, ensuring it doesn’t hang by the brake line.
3. Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
4. Install the new rotor, ensuring it sits flush against the hub.

4. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Clean the caliper bracket using brake cleaner.
Install new brake pads into the caliper bracket.

5. Reassemble and Torque Components

Reattach the caliper over the new brake pads.
Tighten caliper bolts to the manufacturer’s specified torque (typically around 25-30 ft-lbs).
Reinstall the wheel and tighten lug nuts in a crisscross pattern to ensure even pressure.

6. Test Drive

Lower the vehicle back to the ground.
Test the brakes at low speeds before taking it on the road to ensure proper function.
