Solution

1. Preparation

Gather tools and materials required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Brake Fluid Inspection

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Check the fluid level; it should be between the “MIN” and “MAX” marks.
- If low, top off with the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner’s manual).

3. Brake Booster Check

Sub-steps:
- With the engine off, pump the brake pedal until it feels firm.
- Start the engine while pressing the pedal; it should sink slightly if the brake booster is functioning properly.
- If the pedal remains hard, the brake booster may need to be replaced.

4. Brake Line and Master Cylinder Inspection

Sub-steps:
- Inspect the brake lines for any signs of corrosion or leaks.
- Check the master cylinder for fluid leaks around the seals.
- If leaks or corrosion is found, replace the affected components.

5. Brake Pad and Rotor Assessment

Sub-steps:
- Remove the wheel to access the brake components.
- Inspect the brake pads for thickness; replace if they are below the manufacturer’s recommended minimum.
- Check the rotors for scoring or warping; replace if necessary.

Tools Required:

OBD-II scanner
