Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Replace Brake Pads and Rotors

Tools Required: Socket set, jack stands, torque wrench, brake cleaner, and bungee cord.
Remove the wheel using a socket set.
Support the caliper with a bungee cord to prevent strain on the brake line.
Remove the caliper bolts and slide the caliper off the rotor.
Remove the old brake pads and inspect the rotor for warpage or scoring.
If the rotor is damaged, remove it by unscrewing the retaining screws and slide it off the hub.
Install new brake rotors and pads, ensuring they are properly seated.
Reattach the caliper and torque the bolts to manufacturer specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and lower the vehicle.

3. Replace Brake Fluid

Tools Required: Brake fluid bleeder kit, container for old fluid.
Open the brake fluid reservoir and use a brake fluid bleeder kit to remove old fluid.
Refill with new manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Bleed the brakes by starting from the furthest wheel to the closest, ensuring no air bubbles are present.

4. Repair or Replace Brake Switch

Tools Required: Multimeter, screwdriver.
Locate the brake switch, usually near the brake pedal.
Disconnect the wiring harness and test for continuity with a multimeter.
If faulty, replace the brake switch with a new part and reconnect the wiring.

5. Reset the ABS Module

Tools Required: OBD-II scanner.
After repairs are complete, use an OBD-II scanner to clear any stored error codes in the ABS module.
Follow the scanner's instructions to reset the system.
