Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Gather safety gear (gloves and goggles).

2. Inspect and Remove Wheel

Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the wheel by fully unscrewing the lug nuts.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect Brakes

Sub-steps:
1. Visually inspect brake pads for uneven wear; replace if worn down.
2. Measure rotor thickness and inspect for warping using a caliper; replace if out of specification.
3. Clean the brake components using brake cleaner.
Tools Required: Brake cleaner, caliper gauge.

4. Replace Components if Necessary

Sub-steps:
1. If pads are worn, remove the caliper by unscrewing the caliper bolts, then replace the pads.
2. If rotors are warped, remove the rotor by unscrewing the retaining screws and slide it off the hub; install the new rotor.
Torque Values: Refer to the vehicle’s service manual for specific torque specifications for caliper bolts and rotor screws.
Tools Required: Socket set, torque wrench.

5. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle carefully and then fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
Tools Required: Lug wrench.
