Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Locate the Leak

Sub-steps:
- Remove the engine cover (if applicable) to access brake components.
- Check the brake fluid reservoir to confirm low levels.
- Use a flashlight to inspect brake lines, calipers, and the master cylinder for any signs of leakage.
Tools Required: Flashlight, socket set (if covers need removal)

3. Repair or Replace Damaged Components

Sub-steps:
- If leaks are found in the brake lines, replace the damaged section with new brake line tubing.
- If the master cylinder is leaking, remove it by unbolting it from the brake booster and replace it with a new unit.
- For leaking calipers, remove and replace the caliper, ensuring to bleed the brake system afterward.
Tools Required: Wrenches, brake line flaring tool (if applicable), brake fluid, torque wrench
Safety Warnings: Always ensure the brake system is depressurized before working on it.

4. Refill Brake Fluid

Sub-steps:
- Use the appropriate brake fluid type (refer to the owner's manual) to refill the reservoir.
- Ensure the fluid level is at the recommended level.
- Replace the reservoir cap securely.
Tools Required: Funnel

5. Bleed the Brake System

Sub-steps:
- Locate the bleeder screws on each brake caliper.
- Using a helper, pump the brake pedal to build pressure, then open the bleeder screw to allow air and old fluid to escape.
- Repeat until clear fluid without air bubbles emerges, then tighten the bleeder screw.
Tools Required: Brake bleeder kit or tubing, wrench
Safety Warnings: Ensure brake fluid is not spilled on painted surfaces as it can cause damage.
