2
Check the brake pads for thickness and signs of uneven wear.
3
Examine the brake calipers for proper operation and any sticking.
4
Inspect the suspension components, including control arms and bushings, for wear or damage.
5

Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on where the shaking is felt.
Secure the vehicle with jack stands.

3. Inspect and Replace Brake Rotors

Remove the wheel:
- Use a lug wrench to loosen and remove the lug nuts.
- Take off the wheel to access the brake components.
Remove brake caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it without stressing the brake line.
Inspect rotors:
- Measure rotor thickness with a micrometer to ensure it meets specifications.
- Check for warping using a runout gauge.
Replace rotors:
- If warped or below thickness specifications, install new rotors.
- Torque the rotor retaining screws as per manufacturer specifications.

4. Inspect and Replace Brake Pads

Remove brake pads:
- Slide the brake pads out from the caliper bracket.
Inspect brake pads:
- Check for uneven wear; replace if worn down below the minimum thickness.
Install new brake pads:
- Apply brake grease to the backing of the new pads.
- Slide the new pads into the caliper bracket.

5. Reassemble and Test

Reattach brake caliper:
- Slide the caliper back over the new pads and rotor.
- Torque the caliper mounting bolts to manufacturer's specifications.
Reinstall the wheel:
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and then torque the lug nuts to the manufacturer's specifications.
