Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for wear indicators and thickness.
3
Examine the brake calipers for proper operation and any signs of sticking.
4
Inspect suspension components (control arms, tie rods, and ball joints) for wear or damage.
5
Verify tire balance and alignment to rule out related issues.

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Remove Wheel

Using a socket set, loosen the lug nuts on the affected wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Use a dial indicator to check for warping; if warped beyond specifications (usually 0.002 inches), replace the rotor.
- Clean the rotor surface with brake cleaner.
Inspect Brake Pads:
- Check the thickness of the pads; if below 3mm, replace them.
- Remove the caliper bolts and slide the caliper off the rotor.
- Replace pads by sliding them out and inserting new pads into the caliper bracket.
Check Calipers:
- Ensure calipers move freely. If sticking, consider rebuilding or replacing the caliper.

4. Reassemble Components

Reattach the caliper over the new pads and secure with the caliper bolts (torque to manufacturer specifications).
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque the lug nuts to specification (typically around 80-100 ft-lbs).

5. Test Drive

Conduct a test drive to ensure that the shaking has been resolved and that the brakes are functioning properly.
