Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the car is parked on a level surface and engage the parking brake.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.

2. Remove Wheel

Loosen lug nuts slightly while the wheel is still on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the mounting bolts using a socket set.
Carefully slide the caliper off the brake pad; support it with a bungee cord or similar to avoid stressing the brake line.
Remove the old brake pads from the caliper bracket.
Sub-steps:
- Inspect old pads for wear; if worn down to the metal, they must be replaced.
- Clean the caliper bracket and rotor using brake cleaner.
- Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check rotors for any damage; if they are scored or warped, they should be replaced.
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install new rotors, ensuring they are properly seated and secured.

5. Reassemble Brake Assembly

Reattach the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands.
Torque the lug nuts to specifications in a crisscross pattern.
Pump the brake pedal to ensure proper brake pad seating before test driving.
