Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Use wheel chocks for added safety.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel.

3. Inspect and Replace Brake Rotors (if necessary)

Inspect the rotors: Use a dial indicator to measure run-out. Replace if warped beyond specifications (usually more than 0.002 inches).
Remove caliper: Unbolt the caliper from the bracket. Secure it out of the way without stressing the brake line.
Remove rotor: Unscrew any retaining screws if equipped. Slide the rotor off the hub.
Install new rotor: Place the new rotor onto the hub, ensuring it is properly seated.

4. Inspect and Replace Brake Pads (if necessary)

Inspect pads: Check for wear indicators. Replace if less than 3mm thick.
Remove pads: Slide the pads out of the caliper bracket.
Install new pads: Position new pads in the bracket. Ensure they are seated correctly.

5. Reassemble and Lower Vehicle

Reattach the caliper, ensuring it is secured to the bracket.
Reinstall the wheel and tighten lug nuts in a star pattern to the manufacturer’s torque specifications (usually around 76 ft-lbs for a Corolla).
Lower the vehicle back to the ground.

6. Test Brake System

Pump the brake pedal to seat the pads against the rotor.
Conduct a test drive to ensure the issue is resolved and brakes function properly.

Tools Required:

Jack and jack stands
Lug wrench
