Solution

1. Preparation

Gather necessary tools and parts.
Work on a flat, level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts on the wheel associated with the shaking.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Rotors

Sub-step 1: Check the rotor surface for warping or scoring. Use a straight edge to check for flatness.
Sub-step 2: Measure rotor thickness using a micrometer. If below specifications, replace the rotor.
Sub-step 3: If the rotor is warped, it may need resurfacing or replacement.

4. Replace Brake Pads (if necessary)

Sub-step 1: Remove the caliper bolts with a socket wrench.
Sub-step 2: Carefully slide the caliper off the rotor and support it using a bungee cord to avoid straining the brake line.
Sub-step 3: Remove the old brake pads from the caliper bracket.
Sub-step 4: Install new brake pads, ensuring they are properly seated.

5. Reassemble and Check Components

Sub-step 1: Reinstall the caliper over the new pads and secure it with the caliper bolts.
Sub-step 2: Reattach the wheel and hand-tighten the lug nuts.
Sub-step 3: Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
