Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during repair.

2. Inspect and Replace Brake Fluid

Sub-steps:
- Remove the master cylinder cap and check the brake fluid level.
- If low, use a brake fluid extraction tool to remove old fluid from the reservoir.
- Refill the reservoir with the recommended DOT 3 brake fluid.
- Bleed the brake system to remove air bubbles; start from the farthest wheel from the master cylinder.

3. Inspect and Replace Brake Pads and Rotors

Sub-steps:
- Loosen the lug nuts on the wheel and lift the vehicle using a jack.
- Remove the wheel to access the brake assembly.
- Inspect the brake pads for thickness; replace if less than 3mm.
- Check the rotors for warping or grooves; replace if necessary.
- Remove the caliper by unbolting it and slide it off the rotor.
- Install new pads and reassemble the caliper, ensuring it is properly torqued.

4. Inspect Brake Lines and Hoses

Sub-steps:
- Visually inspect all brake lines and hoses for cracks, leaks, or corrosion.
- Replace any damaged lines or hoses with OEM parts.
- Recheck the tightness of all connections.

5. Test Brake Booster

Sub-steps:
- With the engine off, pump the brake pedal several times to deplete vacuum.
- Hold the pedal down and start the engine; the pedal should drop slightly as the booster engages.
- If there is no change, the brake booster may need replacement.
