Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, safety glasses, gloves.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle depending on which brakes are being serviced.
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Using a lug wrench, remove the lug nuts and take off the wheel to access the brake components.

4. Inspect Brake Components

A. Check Brake Pads

Remove the brake caliper by loosening the caliper bolts with a socket set.
Slide the caliper off the brake pads and inspect the pads for wear. Replace if thickness is less than 3mm.

B. Inspect Brake Rotors

Check the rotors for deep grooves or scoring. If the surface is damaged, the rotors should be resurfaced or replaced.
Measure rotor thickness to ensure it meets manufacturer's specifications.

5. Replace Components if Necessary

If brake pads are worn, remove them and replace with new pads.
If rotors are damaged, remove and replace with new rotors, ensuring proper torque specifications are followed (usually around 80-100 lb-ft for rotor bolts).

6. Reassemble and Test

Reattach the caliper over the new pads or rotors and tighten caliper bolts to specification.
Reinstall the wheel and hand-tighten lug nuts before lowering the vehicle.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
