Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on where the shaking occurs).
Secure with jack stands for safety.

3. Remove Wheels

Use a lug wrench to remove the wheel nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Rotors

Inspect Rotors:
- Check for warping using a dial indicator or visually inspect for grooves and rust.
Replace if necessary:
- Use a socket set to remove caliper bolts.
- Remove the brake caliper and hang it with a bungee cord (do not let it dangle from the brake line).
- Remove the old rotor and install a new one, ensuring it is properly seated.
- Torque the caliper bolts to manufacturer specifications (typically around 20-25 ft-lbs).

5. Inspect and Replace Brake Pads

Inspect Pads:
- Check for thickness; replace if they are below manufacturer specifications (usually less than 3mm).
Replace if necessary:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring the anti-rattle clips are in place.
- Apply brake grease to the back of the pads to prevent squeaking.

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the correct specification (typically 76-80 ft-lbs).
Repeat for the opposite side if necessary.
