Solution

1. Preparation

Gather tools and ensure the vehicle is on a flat surface.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

2. Inspect and Replace Brake Rotors

Sub-steps:
- Remove the brake caliper by unscrewing the caliper bolts (use a socket set).
- Hang the caliper using a bungee cord to avoid straining the brake line.
- Remove the brake pads from the caliper bracket.
- Remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
- Check for warping using a dial indicator; replace if warped beyond manufacturer specifications (usually more than 0.002 inches).
- Install new rotors, ensuring they are clean and free of grease.

3. Replace Brake Pads

Sub-steps:
- Insert new brake pads into the caliper bracket.
- Ensure the anti-squeal shims are in place if applicable.
- Reinstall the brake caliper over the new pads and torque caliper bolts to manufacturer's specifications (usually around 25-35 ft-lbs).

4. Reassemble and Test

Sub-steps:
- Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).
- Lower the vehicle from the jack stands.
- Test drive the vehicle to ensure the shaking is resolved.
