Diagnostic Steps

1
Inspect the brake fluid reservoir for current fluid level and condition.
2
Check for visible leaks in brake lines, hoses, and around the master cylinder.
3
Inspect the brake calipers and wheel cylinders for signs of leakage.
4
Examine the brake pads for wear and ensure they are properly seated.
5

Solution

1. Preparation

Tools Required: Socket set, brake fluid, clean rags
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Repair Leaks

Visual Inspection:
- Use a flashlight to thoroughly inspect all brake lines, hoses, and connections for leaks.
- Pay special attention to the master cylinder and both front and rear brake calipers.
Identify Leak Source:
- If a leak is found, determine if it is from a hose, line, or component and mark the area.
Replace Damaged Parts:
- For damaged brake lines or hoses, use the socket set to remove the faulty section and replace it with a new part.
- If the master cylinder is leaking, it may need replacement; follow the steps in the next section.

3. Refill Brake Fluid

Open Brake Fluid Reservoir:
- Remove the cap from the brake fluid reservoir.
Add New Brake Fluid:
- Using clean brake fluid, fill the reservoir to the recommended level without overfilling.
Secure the Cap:
- Replace the cap securely to prevent contamination.

4. Bleed Brake System (if necessary)

Prepare for Bleeding:
- Have a helper pump the brake pedal several times and hold it down.
Open Brake Bleeder Valve:
- Starting from the wheel farthest from the master cylinder, loosen the bleeder valve on the brake caliper.
Bleed the Brakes:
- Allow fluid and air to escape until a steady stream of fluid flows without bubbles, then close the valve.
- Repeat for each wheel, moving closer to the master cylinder.
Check Fluid Level Again:
- Ensure the fluid level in the reservoir remains adequate throughout the bleeding process.
