Solution

1. Preparation

Gather tools and parts needed for the repair.
Safely lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake components.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner.
Remove the caliper by unscrewing the caliper bolts; hang it securely to avoid strain on the brake line.
Remove the brake pads from the caliper bracket.
Use a dial indicator to check rotor runout; if it exceeds specifications (typically 0.002 inches), replace the rotors.
Remove the rotor by unscrewing the retaining screws if present, and slide it off the hub.
Clean the hub surface with brake cleaner before installing the new rotor.
Install the new rotor and secure it with the retaining screws (if applicable).

3. Replace Brake Pads

Apply brake grease to the backing of the new pads to prevent squeaking.
Install the new brake pads into the caliper bracket.
Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (usually around 25-30 Nm).

4. Reassembly and Test

Reinstall the wheel and lower the vehicle.
Torque the wheel bolts to manufacturer specifications (usually around 120 Nm).
Pump the brake pedal to ensure the caliper piston resets.
Conduct a short test drive to ensure brakes function properly and monitor for shaking.
