Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Tools Required: Lug wrench, jack, jack stands.
Loosen lug nuts slightly before lifting the vehicle.
Use the jack to raise the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket wrench.
Carefully lift the caliper off the rotor and support it with a wire hanger or bungee cord (do not let it dangle by the brake line).
Remove the old brake pads from the caliper bracket.
Compare old pads to the new ones to ensure proper fit.
Install new brake pads, ensuring they are positioned correctly in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, they should be replaced.
Remove the caliper bracket by unscrewing the bracket bolts.
Slide the rotor off the hub. If it is stuck, tap it gently with a hammer.
Install the new rotor, ensuring it is properly seated on the hub.

5. Reassemble Brake Components

Reattach the caliper bracket and torque the bolts to manufacturer specifications (typically 25-35 ft-lbs).
Reinstall the caliper over the new brake pads and secure with caliper bolts (torque to manufacturer specifications).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Remove the jack stands and lower the vehicle using the jack.
Tighten the lug nuts to the specified torque value (usually 75-100 ft-lbs) in a crisscross pattern for even distribution.
