2
Check the brake pads for wear and proper installation.
3
Examine the wheel alignment and suspension components for damage or excessive play.
4
Test drive the vehicle to confirm the shaking occurs at specific speeds or brake pressures.
5

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves and goggles.

2. Lift and Secure the Vehicle

Use a jack to lift the front of the vehicle.
Secure it with jack stands for safety.
Remove the front wheels using a lug wrench.

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Remove the caliper bolts using a socket set.
Carefully detach the caliper and support it with a bungee cord (do not let it hang).
Remove the rotor by unscrewing any retaining screws; if stuck, gently tap with a hammer.
Check for warping using a dial indicator; replace if warped beyond tolerance (usually 0.002 inches).

B. Replace Brake Pads

Remove old pads and check for wear indicators.
Install new brake pads, ensuring they are properly oriented and seated in the caliper bracket.

4. Reassemble and Lower Vehicle

Reinstall the rotor and caliper, tightening caliper bolts to the manufacturer's torque specifications (typically around 20-25 ft-lbs).
Reattach the wheel and lug nuts, torquing them to specification (usually 76-83 ft-lbs).
Lower the vehicle back to the ground and repeat for the rear brakes if necessary.
