Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the front wheel using a socket set.
2. Remove the brake caliper by unbolting it from the bracket and securing it to the suspension to avoid stress on the brake line.
3. Remove the brake rotor; check for warping using a dial indicator gauge.
4. If warped, replace the rotors with new OEM or high-quality aftermarket rotors.
5. Install the new rotor, ensuring it is seated properly.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Check the thickness of the brake pads; if less than 3mm, replace them.
2. Remove the old brake pads from the caliper bracket.
3. Install new brake pads, ensuring they are properly aligned with the rotor.
4. Apply brake grease to the backing of the pads to prevent noise.

4. Wheel Alignment and Tire Inspection

Sub-steps:
1. Inspect all tires for uneven wear; replace any damaged tires.
2. Take the vehicle to a professional for a wheel alignment adjustment.
3. Balance the tires if necessary, ensuring they are properly inflated.

5. Reassemble and Test

Sub-steps:
1. Reinstall the brake caliper over the new pads.
2. Secure the caliper with the appropriate torque specification (typically around 25-35 ft-lbs).
3. Reattach the front wheel and torque the lug nuts to the specified value (usually around 76-83 ft-lbs).
4. Reconnect the battery and conduct a test drive to ensure the shaking is resolved.
