Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and set the parking brake.
Wear appropriate safety gear (gloves and goggles).

2. Addressing Error Codes

Code Analysis: Cross-reference retrieved error codes with a repair manual to identify specific issues.
Clear Codes: Use the OBD-II scanner to clear the codes after addressing the issues.

3. Brake Fluid Service

Inspect and Replace Fluid:
- Remove the brake fluid reservoir cap.
- Use a siphon to extract old fluid.
- Refill with new brake fluid (DOT 3 or DOT 4 as specified).

4. Brake Component Replacement

Remove Old Components:
- Lift the vehicle safely and remove the wheels.
- Unbolt and remove the calipers and pads.
Install New Components:
- Install new brake pads and ensure proper alignment.
- Reassemble calipers and torque bolts to manufacturer specifications (generally around 20-30 ft-lbs).

5. Brake System Bleeding

Bleed Brakes:
- Start at the farthest wheel from the master cylinder.
- Open the bleeder valve, pump the brake pedal, and close the valve before releasing the pedal.
- Repeat until no air bubbles are visible, then move to the next wheel.

6. Final Checks

Inspect and Test:
- Reinstall the wheels and lower the vehicle.
- Start the engine and pump the brakes to establish pressure.
- Test drive the vehicle at low speeds to ensure proper functioning of the brake system.
