Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the engine.
Engage the parking brake and place wheel chocks behind the rear wheels.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Instructions:
1. Open the hood and locate the brake master cylinder.
2. Remove the cap and check the brake fluid level.
3. If low, refill with the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
4. Replace the cap securely.

3. Inspect Brake Components

Tools Required: Socket set, torque wrench, brake cleaner
Instructions:
1. Remove the wheel to access the braking components.
2. Inspect brake pads for thickness; replace if worn below 3mm.
3. Check brake rotors for scoring or warping; replace if necessary.
4. Clean any debris from the brake components using brake cleaner.

4. Check for Leaks

Tools Required: Flashlight
Instructions:
1. Inspect the brake lines for any signs of leaks or corrosion.
2. Check calipers for fluid seepage.
3. Tighten any loose connections or replace damaged lines as needed.

5. Test Brake Booster

Tools Required: None
Instructions:
1. With the engine off, pump the brake pedal a few times until it feels firm.
2. Start the engine while pressing the brake pedal; it should sink slightly if the booster is functioning properly.
3. If the pedal does not change or feels firm, the brake booster may need replacing.
