Solution

1. Preparation

Tools Required: Socket set, torque wrench, brake pad spreader, jack stands, wheel chocks, brake cleaner, rubber mallet.
Park the vehicle on a flat surface and engage the parking brake.
Loosen the lug nuts on the front or rear wheels while the vehicle is on the ground.

2. Raise the Vehicle

Use a jack to lift the vehicle and support it securely with jack stands.
Remove the wheels carefully after fully loosening the lug nuts.

3. Remove Old Brake Pads and Rotors

Locate the brake caliper: Identify the caliper securing the brake pads.
Remove caliper bolts: Use the socket set to remove the caliper mounting bolts.
Detach the caliper: Carefully slide the caliper off the rotor. Do not disconnect the brake line; support the caliper with a wire or bungee cord.
Remove the old brake pads: Slide the old pads out of the caliper bracket.
Remove the rotor: If applicable, remove the retaining screws (if any) and slide the rotor off the hub. Use a rubber mallet if necessary to loosen it.

4. Install New Brake Rotors

Clean the new rotor: Use brake cleaner to remove any protective coating on the new rotor.
Position the new rotor: Slide the new rotor onto the hub, ensuring it sits flush.
Secure the rotor: Replace any retaining screws removed earlier.

5. Install New Brake Pads

Insert new brake pads: Slide the new pads into the caliper bracket, ensuring they are properly aligned.
Compress the caliper piston: Use a brake pad spreader to push the caliper piston back into the caliper housing to make space for the new pads.
Reattach the caliper: Position the caliper over the new pads and secure it with the caliper bolts. Tighten to the manufacturer's specified torque (typically around 35-40 Nm).

6. Reassemble the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground and fully tighten the lug nuts to the manufacturer’s specifications (generally 120 Nm).
