Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Retrieve and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve any active and stored fault codes.
Document the codes for reference.
Clear the codes and see if they reappear after a test drive.

3. Inspect and Replace Brake Components

Brake Pads and Rotors:
- Remove the wheel using a socket set.
- Inspect brake pads for thickness (should be at least 3mm).
- Measure rotor thickness; replace if below manufacturer specifications.
- Replace pads and rotors if worn.
Brake Fluid:
- If the fluid level is low, identify and fix any leaks.
- Replace old brake fluid with the recommended type (DOT 4 for most Volvo models).

4. Repair Electrical Issues

Inspect wiring harnesses and connectors for damage.
Clean any corroded connectors using electrical contact cleaner.
Repair or replace damaged wiring as necessary.

5. Reassemble and Test

Reinstall the wheel and torque lug nuts to manufacturer specifications (typically 100-120 Nm).
Lower the vehicle and pump the brake pedal to restore pressure.
Conduct a test drive to ensure proper brake operation and check for reoccurring codes.
