Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Dial indicator
Brake cleaner
Safety goggles and gloves

2. Remove Wheels

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

3. Inspect Brake Rotors

Use a dial indicator to measure rotor thickness and check for warping.
If warping is detected (beyond manufacturer's specifications), replace the rotors.
Clean rotors with brake cleaner before reinstallation.

4. Inspect Brake Pads

Remove the caliper bolts and carefully slide the caliper off the rotor.
Check the brake pads for wear; replace if they are below the minimum thickness.
Ensure that the brake pads are evenly worn and properly seated in the caliper.

5. Reassemble Components

Reinstall the caliper over the rotor and secure it with bolts.
Place the wheels back on and hand tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specification.
