Chevrolet Corvette Master Cylinder and Parts
It goes without saying that a functioning brake system is an essential part of your Corvette. While your brakes are made up of a series of interworking parts, the brake system itself is driven by the master cylinder. If your vehicle quits slowing down or coming to a stop effectively, you might need to replace the Chevrolet Corvette master cylinder and parts.How do brake systems on a Corvette work?
The braking process for a Corvette is a linear one. It begins with your foot pushing down on the pedal and ends with pressure being applied to the wheel cylinder, which causes your vehicle to slow or stop. When the brake pedal is pushed, it forces a piston into what is known as the master cylinder. The master cylinder then causes that pressure to transfer through the brake lines and into the wheel cylinder.What are master cylinders?
The purpose of brake master cylinders is to transform the non-hydraulic pressure from your foot pressing on the brake pedal into hydraulic pressure. This is accomplished due to the master cylinder being filled with brake fluid. As the piston pushes into the cylinder, it displaces the brake fluid and forces the fluid into the brake lines. The hydraulic pressure helps to split up the distribution of the fluid evenly among all four brakes. This process leads to a great deal of pressure being applied to the wheel cylinders with a simple pump of the brakes.What types of master cylinders are there for a Corvette?
Two types of master cylinders have been used in Corvettes:
- Single-circuit master cylinders: Single-circuit brake master cylinders were more commonly used in early model Corvettes. These systems have one piston within a single fluid reservoir inside of the cylinder. This piston is tasked with applying pressure to all of the brakes on the vehicle. Although these cylinders can provide effective pressure to both the front and the rear brake systems, the single circuit runs the risk of total brake failure if a line leaks and compromises the pressure within the circuit. With only one compromised circuit, your Corvette vehicle would be rendered unable to brake.
- Double-circuit master cylinders: The aptly named double-circuit cylinder includes one master cylinder that houses two separate reservoirs and pistons. These separate systems operate independently of each other. That means that one piston services the front set of brakes while the second piston serves the rear set. This dual-circuit setup is beneficial in the case of line failure. If a line fails and pressurization is lost in one circuit, then the other circuit will still be be able to power the brakes on one set of wheels.
