Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Lift the vehicle using a jack and secure with jack stands.
Remove the wheel to access the braking components.

3. Inspect and Replace Brake Rotors

Tools Required: Dial indicator, torque wrench.
Use a dial indicator to measure the rotor runout; if it exceeds manufacturer specifications, replace the rotor.
If replacement is necessary, remove the caliper by unbolting it and support it with a wire.
Remove the rotor and install the new rotor, ensuring it is properly seated.
Torque bolts to manufacturer specifications.

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads. If they are below the minimum thickness, replace them.
Remove the caliper bracket if necessary, then remove the old pads.
Install new pads, ensuring they fit snugly in the caliper bracket.

5. Reassemble and Test

Reattach the caliper and wheel.
Torque the lug nuts to the manufacturer's specifications.
Lower the vehicle and perform a test drive to ensure the shaking is resolved.
