Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a jack to raise the vehicle and secure with jack stands.
Remove the wheel using a socket set.

3. Inspect and Replace Brake Pads

Inspect: Check the brake pads for wear indicators. If the pads are worn down to the metal backing, they need replacement.
Remove: Use a socket to remove the caliper bolts and slide the caliper off the rotor.
Replace: Remove the old pads and install new pads, ensuring they are properly aligned and seated.

4. Inspect and Replace Brake Rotors

Inspect: Check the rotors for scoring or warping using a micrometer or ruler.
Replace: If damaged, remove the rotor by unscrewing the retaining screws and pulling it off the hub. Install new rotors, ensuring they are properly torqued to manufacturer specifications (typically around 80-100 ft-lbs).

5. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's torque specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and lower the vehicle.

6. Final Check

Reconnect the negative battery terminal.
Pump the brake pedal a few times to ensure proper seating of the new pads and restore brake pressure.
