Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Allow the engine to cool if it has been running.

2. Inspect Brake Fluid Reservoir

Tools Required: None
Open the hood and locate the brake fluid reservoir.
Check fluid level against the minimum and maximum markings on the reservoir.
If low, top off with the appropriate brake fluid (DOT 3 or DOT 4, refer to owner's manual).

3. Inspect Brake Lines and Hoses

Tools Required: Wrench set, flashlight
Start from the brake fluid reservoir and trace the brake lines to each wheel.
Use a flashlight to inspect for any signs of leaks, corrosion, or damage.
Tighten any loose connections and replace any damaged lines or hoses.

4. Examine Brake Calipers and Wheel Cylinders

Tools Required: Jack and jack stands, socket set
Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake caliper.
Inspect the caliper for any signs of brake fluid leaks around the piston seals.
For rear brakes, check the wheel cylinder for signs of leaks and replace if necessary.

5. Test and Clean

Tools Required: Brake cleaner, cloths
If leaks are found, replace the affected components (caliper, hose, line).
Clean any spilled brake fluid with brake cleaner and a cloth.
Ensure all connections are secure and free of leaks after repairs.
