Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during repairs.

2. Remove Wheel

Loosen the lug nuts while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor without disconnecting the brake line.
Remove the old brake pads from the caliper bracket.
Compare the old pads with new ones to ensure proper fit.
Install new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotor surface for grooves or damage.
If the rotors are damaged, remove the caliper bracket bolts and remove the rotor.
Install the new rotor and torque the bolts to the manufacturer’s specifications (typically around 80-90 Nm).
Reattach the caliper over the new rotor and secure it with the caliper bolts.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and fully tighten lug nuts in a star pattern to the manufacturer's torque specifications (usually around 120 Nm).
Reconnect the battery.
Start the vehicle and pump the brakes to ensure proper pressure before test driving.
