Brake Hydraulics
Hydraulic pressure in the brake system pushes the brake pads or shoes against the rotors or drums. Keeping the system sealed and full of brake fluid helps ensure your brakes stay in working order. Brake fluid leaks or low brake fluid pressure should be addressed promptly to be certain your vehicle can be driven safely.
Brake System Pressure
Since hydraulic brakes are a closed system, any small leak can decrease the effectiveness of the brakes or cause them to fail in extreme cases. The pressure in most hydraulic brake systems is created in the master cylinder, typically with the help of a power brake booster. The pressure moves through the brake lines, and on many vehicles, through proportioning valves to the brake calipers or wheel cylinders. As hydraulic brake parts begin to wear, you may notice leaks around the master cylinder, brake hoses, brake lines, calipers, or wheel cylinders. However, you may not realize the metal brake lines or rubber brake hoses are wearing out until a pinhole, crack, or leak develops or, in worst case, the line or hose bursts and fails. This can cause your brakes to fail immediately, so adding brake system inspections to your regular maintenance is essential.
