Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle’s 12V battery to ensure safety during electrical work.
Tools Required: OBD-II scanner, multimeter, socket set, brake fluid, brake cleaner.

2. Address Error Codes

a. Clear Error Codes: Use the OBD-II scanner to clear all existing brake-related error codes.
b. Test Drive: Perform a test drive to determine if any error codes reappear and monitor brake performance.

3. Inspect and Replace Components

a. Brake Pads and Rotors: If worn, remove the wheel using a socket set, then:
- Remove caliper bolts and lift the caliper away.
- Replace pads and inspect rotors; resurface or replace as necessary.
b. Brake Fluid: If contaminated or low:
- Remove the master cylinder cap.
- Use a brake bleeder kit to flush old fluid and replace it with new brake fluid according to manufacturer specifications.
