Solution

1. Preparation

Gather necessary tools and parts.
Safety gear: gloves and safety goggles.
Make sure the vehicle is parked on a level surface and turn off the engine.

2. Inspect Brake Fluid Reservoir

Tools Required: None
Open the hood and locate the brake fluid reservoir.
Check the fluid level against the markings on the reservoir. If low, add the correct type of brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Inspect the reservoir cap for cracks or damage.

3. Check Brake Lines and Hoses

Tools Required: Visual inspection only
Follow the brake lines from the master cylinder to the wheels.
Look for any signs of wear, such as cracks, bulges, or corrosion.
Ensure that all connections at the brake lines and hoses are tight.

4. Examine Brake Calipers and Wheel Cylinders

Tools Required: Jack and jack stands, socket set
Safely lift the vehicle and remove the wheel.
Inspect the brake calipers closely for signs of fluid leakage. Look for wetness or residue around the caliper piston seals.
Check wheel cylinders (if present) for similar signs of leakage.

5. Repair or Replace Affected Components

If leaks are found in the brake lines, calipers, or hoses, replace the damaged part.
Use appropriate tools to disconnect and replace lines or calipers, ensuring to use new seals where applicable.

6. Refill and Bleed Brake System

Tools Required: Brake fluid, vacuum bleeder (optional)
After replacing any components, refill the brake fluid reservoir.
Bleed the brakes at each wheel to remove any air from the system, ensuring proper brake function.
