Solution

1. Preparation

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

2. Remove Wheels

Loosen wheel lug nuts with a socket wrench before lifting the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels by fully unscrewing the lug nuts.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Measure rotor thickness with a micrometer and check for warping using a dial indicator.
- If warping exceeds manufacturer specifications, proceed to replace.
Remove Rotors:
- Unscrew the caliper mounting bolts and slide the caliper off the rotor.
- Remove any retaining screws securing the rotor and pull it off the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective coating.
- Install the new rotors onto the hub and secure with retaining screws.

4. Inspect and Replace Brake Pads

Inspect Pads:
- Check for adequate thickness and even wear on brake pads.
Replace Pads:
- Compress the caliper piston using a caliper tool or C-clamp.
- Remove the old pads and install new pads in the caliper bracket.
- Reattach the caliper over the new pads and tighten the caliper mounting bolts to manufacturer torque specifications.

5. Reassemble and Test

Reinstall wheels and tighten lug nuts in a crisscross pattern to manufacturer specifications.
Lower the vehicle and remove jack stands.
Test the brakes gently at low speed before driving normally to ensure proper function.
