Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical issues.

2. Lift the Vehicle

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

3. Remove Wheel

Use a lug wrench to remove the wheel where the shaking is most pronounced.
Set the wheel aside in a safe location.

4. Inspect and Replace Brake Components

A. Inspect Rotors

Check for warping: use a dial indicator to measure rotor runout.
If warped, replace the rotors with new ones. Torque the new rotors to manufacturer specifications (usually around 80-100 ft-lbs).

B. Replace Brake Pads

Remove the caliper bolts using a socket set; lift the caliper away from the rotor.
Remove old brake pads and inspect the caliper for any debris.
Install new brake pads, ensuring proper orientation and alignment.

5. Reassemble

Reinstall the brake caliper over the new pads and torque the caliper bolts according to manufacturer specifications.
Mount the wheel back onto the hub and hand-tighten the lug nuts before lowering the vehicle.
Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

6. Final Checks

Reconnect the negative battery terminal.
Check brake fluid level and top off if necessary.
