Crown Brake Bleed Screw & Accessories

Almost all modern brake systems are operated by hydraulic components instead of mechanical components. Hydraulic components are simpler and more efficient compared to mechanical components. Hydraulic braking is also less prone to breakdown because it has fewer moving parts. A hydraulic brake system relies on the braking fluid or brake oil to relay and multiply leg muscle input exerted on the brake pedal. Since oil is a liquid that cannot be compressed, it is more efficient in amplifying and transmitting force than the mechanical counterpart. A hydraulic brake mechanism is comprised of a double piston master cylinder, oil reservoir, brake transmission hose, and slave cylinders.

The master cylinder is the one that contains the double pistons. It is the one that initiate and amplifies input force by building pressure. As you step on the brake pedal, pressure is exerted by the double pistons on the brake fluid. Consequently, the brake fluid tries to escape. Since it cannot be compressed, pressure is relayed to the slave cylinders. In turn, the slave cylinders push their respective pistons. These pistons are connected to the brake actuator, typically a caliper or brake shoe. The brake actuator pushes its brake pads against the rotating surface of the brake rotor or brake drum. Increasing friction and compressive force result in the stoppage of the rotating component. The rotating component is connected to the wheel. Consequently, the wheel also stops moving.

Although the brake fluid does not accumulate too much dirt compared to engine oil, it still deteriorates over time. Hence, it needs to be replaced. Deterioration may come in the form of chemical changes in the oil or rust accumulation. A brake bleed screw such as the Crown brake bleed screw is utilized to drain the brake oil. A brake bleed screw is integrated in the brake system. You simply have to unscrew it to drain the brake fluid. Parts Train offers the best brands of aftermarket brake bleed screws.
