Your Buick Regal brakes are an impressively engineered system on your car. Do you know how your Regal brakes work to stop half a ton of rapidly moving metal and plastic at a moment's notice? In most cases, your Buick Regal brakes are a disc braking system, though some older models may use drum brakes. In a disc braking system, your Regal brakes feature several components; some are hydraulic, and others are frictional.

The hydraulic components of your Buick Regal brakes include brake lines, brake hoses, a master cylinder, a brake fluid reservoir, and brake calipers. The list of frictional components for your Regal brakes is much shorter: these are simply your brake pads and brake rotors (sometimes known as brake discs).

The rotors, pads, and calipers of your brakes are located at each wheel, where you will find a brake rotor spinning in the channel of a U-shaped caliper, and two brake pads floating above the caliper on either side of the rotors. Brake lines and brake hose connect the calipers to the master cylinder, and the master cylinder to your brake pedal. When you engage your Regal brakes by depressing the pedal, the force of your step is transmitted and amplified by the hydraulic fluid to the master cylinder, and then to your brake calipers. This causes the calipers to clamp down and bring your brake pads into contact with your brake rotors, which generates the friction your car uses to stop. This is how your brakes work; a true accomplishment of hydraulic engineering.When any component of your Regal brakes is worn or faulty, you can find replacement brakes and brake parts in our extensive online catalogue.
