Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the parking brake is engaged.
Wear safety gloves and goggles for protection.

2. Remove Wheel

Tools Required: Lug wrench, jack, jack stands
Loosen the lug nuts slightly while the wheel is still on the ground.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench
Remove the caliper bolts using a socket set and carefully lift the caliper off the rotor.
Support the caliper using a bungee cord or similar tool to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake hardware (shims and clips) and replace if damaged.
Install new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor's surface for scoring or warping. If damaged, proceed to replace.
Remove the rotor by unscrewing the retaining screws if applicable and sliding it off the hub.
Install the new rotor onto the hub, ensuring it is properly seated.

5. Reassemble and Test

Reattach the caliper over the new brake pads, ensuring it is aligned correctly.
Replace and torque the caliper bolts to manufacturer specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and lug nuts, torqueing them to manufacturer specifications (typically 80-100 ft-lbs).
Lower the vehicle and pump the brake pedal a few times to set the brake pads against the rotors.
