Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Addressing Brake Fluid Issues

If the brake fluid is low or contaminated:
1. Remove the brake fluid reservoir cap.
2. Clean the reservoir area to prevent contamination.
3. Refill with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
4. Replace the cap securely.

3. Replacing Worn Brake Pads and Rotors

If pads or rotors are worn:
1. Remove the wheel using a socket set to access the brake components.
2. Unbolt the caliper and suspend it using a wire (do not let it hang on the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Use a caliper tool to compress the caliper piston.
5. Replace with new brake pads, ensuring proper alignment.
6. If replacing rotors, remove the caliper bracket and unscrew the retaining screws for the rotor.
7. Install the new rotor and reassemble the caliper bracket.

4. Inspecting and Repairing Brake Lines

If leaks are detected:
1. Locate the source of the leak in the brake lines.
2. Cut the affected section and replace it with new brake line tubing.
3. Use a flaring tool to create proper fittings and secure connections with brake line clips.

5. Testing the Brake Booster

For a malfunctioning brake booster:
1. Check for vacuum leaks at the booster connection.
2. Test the booster operation by pressing the brake pedal while the engine is off; you should feel resistance.
3. If faulty, replace the brake booster with a new unit.

6. Repairing ABS Issues

If ABS error codes are present:
1. Inspect wheel speed sensors for dirt or damage.
2. Clean or replace faulty sensors as needed.
3. Clear codes using the OBD-II scanner and perform a test drive.
