Solution

1. Preparation

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

2. Wheel Removal

Tools: Jack and jack stands, lug wrench.
Loosen the lug nuts on the wheels before raising the vehicle.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Remove the caliper by unscrewing the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor, suspending it with a wire to avoid stress on the brake line.
Remove the old rotor by unscrewing any retaining screws if present.
Inspect the new rotor for any shipping debris and install it by aligning it with the hub.
Reattach the caliper over the new rotor and torque the caliper bolts to the manufacturer’s specifications (usually around 25-35 ft-lbs).

4. Inspect and Replace Brake Pads

Remove the existing brake pads from the caliper bracket.
Inspect the brake pads for wear indicators; replace if worn beyond the manufacturer’s specifications.
Apply brake grease to the back of the new pads to reduce noise and ensure smooth operation.
Install the new pads into the caliper bracket.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern to the manufacturer’s torque specifications (typically 100-120 ft-lbs).
Perform a test drive to check for vibrations during braking.
