Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Loosen lug nuts using a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor.
Inspect the brake pads for wear; if they are below the minimum thickness (usually 3mm), replace them.
If replacing, slide new brake pads into the caliper bracket.

4. Check and Replace Brake Rotors

Inspect the rotor surface for grooves or warping. If damaged, remove the rotor by unscrewing the retaining screws (if applicable).
Install new rotors by aligning them on the hub and securing them with screws.
If the rotors are in good condition, clean them with brake cleaner to remove any debris.

5. Reassemble and Test

Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications (typically 20-30 ft-lbs).
Reinstall the wheel and torque the lug nuts in a crisscross pattern to the specified torque (usually 75-100 ft-lbs).
Lower the vehicle and perform a test of the brake system by pressing the brake pedal.
