Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent rolling.
Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, and a caliper tool.

2. Remove Wheel

Loosen lug nuts slightly while the wheel is still on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Check for warping using a dial indicator.
- If warped, replace the rotors.
- Clean the mating surface with brake cleaner.
Inspect Brake Pads:
- Measure the thickness; replace if below manufacturer specifications.
- Ensure pads are wearing evenly; replace if uneven.

4. Reassemble Components

Place new or resurfaced rotors onto the hub, ensuring they are seated properly.
Install new brake pads into the caliper bracket.
Reattach the caliper over the pads and secure it with the caliper bolts.
Torque Specification: Tighten caliper bolts to manufacturer’s recommended torque value.

5. Reattach Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle from jack stands.
Fully tighten lug nuts in a crisscross pattern to the manufacturer's torque specification.

6. Test Brake Function

Pump the brake pedal to ensure proper brake pad contact.
Test drive the vehicle at low speeds to check for vibrations.
