Solution

1. Preparation

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

2. Remove Wheels

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts using a socket wrench and take off the front or rear wheels as needed.

3. Inspect and Replace Brake Rotors

Inspect Rotors: Measure the thickness of the rotors using a micrometer. Check for signs of warping or scoring.
Replace Rotors:
1. Remove the caliper bolts with a socket wrench and detach the caliper.
2. Secure the caliper to the suspension to avoid damaging the brake line.
3. Remove the old rotor by unscrewing any retaining screws or clips.
4. Install the new rotor, ensuring it is seated properly.
5. Reattach the caliper and torque the bolts to the manufacturer’s specifications.

4. Replace Brake Pads

Inspect Pads: Check for uneven wear or thickness below the minimum specification.
Replace Pads:
1. Remove the old brake pads from the caliper bracket.
2. Compress the caliper piston using a brake tool or C-clamp to make room for new pads.
3. Install new pads into the caliper bracket.
4. Reinstall the caliper over the new pads and torque the caliper bolts.

5. Reinstall Wheels and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts in a crisscross pattern to the specified torque.

6. Test Drive

Perform a test drive to ensure that the shaking during braking has been resolved.
