Solution

1. Preparation

Gather necessary tools and parts before starting.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts.
Lift the vehicle using a jack and secure it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Measure rotor thickness and check for warping using a dial indicator.
Replace Rotors (if necessary):
- Remove caliper bolts using a socket set and slide the caliper off the rotor.
- Remove the rotor by sliding it off the hub.
- Install the new rotor ensuring it is seated properly on the hub.
- Reattach the caliper over the new rotor and tighten bolts to the manufacturer's torque specifications (typically around 25-30 Nm).

4. Inspect and Replace Brake Pads

Remove the caliper bracket if necessary to access pads.
Check pads for uneven wear and replace if they are less than 3mm thick.
Apply brake grease to the back of new pads to prevent noise.
Install new pads into the caliper bracket and reattach to the caliper.

5. Reinstall Wheel and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specification (typically around 100-110 Nm).

6. Test Brake System

Reconnect the battery.
Pump the brake pedal to ensure proper brake feel.
Conduct a test drive in a safe area to verify that the shaking has been resolved.
