Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Jack up 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 using a socket set.
Carefully slide the caliper off the rotor and support it without straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper slides for any corrosion and clean them with brake cleaner.
Install new brake pads, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping. If damaged, remove the rotor.
Use a rotor puller if necessary. Clean the hub surface before installing the new rotor.
Install the new rotor and torque to manufacturer specifications.

5. Reassemble Braking System

Reattach the caliper over the new pads and rotor, ensuring it slides back into place without binding.
Reinstall the caliper bolts and torque them to the specified value.
Replace the wheel, tighten the lug nuts loosely, and lower the vehicle.

6. Final Check

Tighten the lug nuts to the specified torque value in a crisscross pattern.
Pump the brake pedal to ensure proper brake pad seating before driving.
