Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear appropriate safety gear (gloves, goggles).

2. Raise the Vehicle

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

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake cleaner, torque wrench.
Remove the wheel to access the brake assembly.
Inspect the brake pads for uneven wear. If they are worn down, replace with new pads.
- Remove the caliper bolts and slide the caliper off the rotor.
- Remove old brake pads and install new ones.
- Torque caliper bolts to manufacturer specifications.

4. Check and Resurface/Replace Brake Rotors

Inspect brake rotors for warping or damage.
If warped, consider resurfacing them or replacing if beyond specifications.
- To replace, remove the rotor by unbolting it from the hub.
- Install new rotor and secure with bolts, torqued to specifications.

5. Inspect and Lubricate Calipers

Check caliper slides for proper movement.
Clean and lubricate caliper slides using brake grease to prevent sticking.

6. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle back to the ground.
Tighten lug nuts to the specified torque.
