Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench, and safety goggles.
Park the vehicle on a level surface and engage the parking brake.
Gather all necessary tools and parts for the repair.

2. Lift the Vehicle

Loosen the lug nuts on the wheels to be serviced before raising the vehicle.
Use a jack to lift the vehicle and securely place it on jack stands.

3. Remove the Wheel

Fully remove the loosened lug nuts and take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and suspend it with a bungee cord to avoid straining the brake line.
Remove the old brake pads and check for excessive wear.
Apply brake cleaner to the caliper and rotor to clean any debris.
Install new brake pads ensuring they are properly positioned.

5. Inspect and Replace Rotors (if necessary)

If rotors are damaged, remove them by unscrewing the rotor retaining screws.
Install new rotors and torque to manufacturer specifications (typically around 80-100 lb-ft).
Reinstall the caliper and torque the caliper bolts to the specified value.

6. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a star pattern to ensure even pressure.

7. Final Checks

Refill brake fluid if necessary and check for leaks.
Pump the brake pedal to seat new pads and ensure proper brake function before test driving.
