Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks to prevent vehicle movement.

2. Remove Front Wheels

Use a jack to lift the front of the vehicle.
Secure with jack stands.
Remove lug nuts using a socket set and take off the front wheels.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to check rotor runout.
- If the runout exceeds manufacturer specifications, proceed with replacement.
Replacement:
- Remove the caliper bolts and detach the brake caliper.
- Suspend the caliper using a wire hanger, avoiding strain on the brake line.
- Remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
- Install the new rotor, ensuring it's flush against the hub.
- Reattach the caliper and torque bolts to manufacturer specifications.

4. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Use a brake pad spreader tool to compress the caliper piston.
Install new brake pads, ensuring they are correctly aligned.
Reinstall the caliper and torque bolts to specifications.

5. Reassemble and Test

Reattach the front wheels and torque lug nuts to manufacturer specifications.
Lower the vehicle and remove wheel chocks.
Pump the brake pedal several times to ensure proper brake function.
Test drive the vehicle to confirm that the shaking issue has been resolved.
