Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is off.
Secure the vehicle with wheel chocks and jack stands.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually inspect the brake pads for wear; replace if they are less than 3mm thick.
Check the brake rotors for scoring or rust; if damaged, they should be resurfaced or replaced.
Inspect the brake calipers for any signs of leakage or sticking.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor and support it (do not let it hang by the brake line).
Remove the old brake pads and clean the caliper bracket with brake cleaner.
Install new brake pads, ensuring they are properly seated.

5. Reassemble and Torque

Reattach the caliper over the new brake pads and tighten the caliper bolts to manufacturer specifications (typically around 20-30 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the specified value (usually around 76 lb-ft).
