Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, brake fluid, brake cleaner, multimeter, and a jack with jack stands.
Ensure the vehicle is parked on a level surface, and the ignition is off.
Disconnect the battery's negative terminal to prevent electrical shorts.

2. Retrieve and Analyze Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Retrieve and note the brake-related error codes for reference.
Clear the codes after noting them to see if they return after repairs.

3. Inspect and Replace Brake Components

Brake Pads and Rotors:
1. Jack up the vehicle and secure it on jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect the brake pads for thickness; replace if less than 3mm.
4. Check the rotors for scoring or warping; machine or replace as necessary.
Brake Fluid:
1. Check the brake fluid level; if low, top off with the recommended fluid type (DOT 3 or DOT 4).
2. If the fluid is dirty or contaminated, perform a brake fluid flush.
Brake Lines:
1. Visually inspect all brake lines for wear or leaks.
2. Replace any damaged lines using appropriate brake line materials.

4. Repair ABS Module (if applicable)

Testing and Repair:
1. Use a multimeter to check the ABS module's power and ground connections.
2. If the module is faulty, follow manufacturer guidelines for replacement or repair.

5. Final Assembly and System Check

Reinstall the wheel and lower the vehicle.
Reconnect the battery terminal.
Start the vehicle and perform a brake system check before driving.
