Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if necessary for safety.

2. Remove Wheel Assembly

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Components

Rotors

Remove the brake caliper by unscrewing the caliper bolts using a torque wrench.
Slide the caliper off the rotor and suspend it using a bungee cord or rope to avoid stress on the brake line.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Inspect for warping using a dial indicator; replace if warped beyond specifications (typically 0.003 inches).
If replacement is needed, install the new rotor, ensuring it is properly seated and fastened.

Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect for even wear; replace if worn down to the minimum thickness.
Apply brake grease to the back of the new pads to reduce noise.
Install new brake pads into the caliper bracket.

4. Reassemble Components

Reinstall the brake caliper over the new pads and rotor, tightening the caliper bolts to the manufacturer's torque specifications.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque.

5. Final Check

Reconnect the battery if it was disconnected.
Pump the brake pedal to ensure proper brake engagement.
Test drive the vehicle to confirm that the shaking during braking has been resolved.
