How to Repair a Vehicle’s Hydraulic System
Vehicle Hydraulic System support is relatively uncomplicated, but it's crucial to the vehicle's safe operation.
Brake Fluid Inspection
The master cylinder is usually located under the hood and close to the firewall on the driver's side. Remove the cover and inspect the gasket or diaphragm. Inspect the cover for damage or plugged vent holes. Clean the vent holes, if necessary.

Check the brake fluid level in the master cylinder. A cast-iron reservoir is generally filled to within 1/4 inch of the top. A plastic reservoir may have fluid level mars. Don't overfill a reservoir. If the fluid has to be added, a flow likely has developed or the pads or shoes are worn. Examine the system carefully to find the leak.
To check for contaminated fluid, put a small amount of brake fluid in a transparent glass jar. If the fluid is dirty or separates into layers, then it's contaminated. Contaminated fluid needs to be replaced.
Contaminated brake fluid can damage rubber components and cause leaks. When replacing contaminated brake fluid, it's required to flush and refill the brake system with new fluid. Always use fluid using a DOT score of 3 or higher. Follow the manufacturer's recommendations.
Check the master cylinder for dampness and flows around the body fittings, particularly at the rear. A leak where it's mounted to the firewall or power brake unit indicates a faulty rear piston seal. The master cylinder has to be replaced or rebuilt.
