Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are affected.
Secure the vehicle on jack stands.

3. Remove the Wheel

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

4. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts with a socket set and gently slide the caliper off the rotor.
- Inspect brake pads for thickness; replace if they are below manufacturer specifications (usually less than 3mm).
- If replacement is needed, remove the old pads and install new ones, ensuring they are correctly positioned.
- Apply brake grease to the back of the new pads to reduce noise.

5. Check and Replace Brake Rotors (if necessary)

Inspect the rotors for any grooves, scoring, or warping.
If damaged, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
Install new rotors, ensuring they are properly seated and torqued to manufacturer specifications.

6. Reassemble and Test

Reattach the brake caliper over the new pads and torque the caliper bolts to specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque.
Reconnect the battery.
