How a Brake Booster and Master Cylinder Work



How Master Cylinders and Combination Valves Work

Brake Types

­T­o increase safety, most modern car brake systems are broken into two circuits, with two wheels on each circuit. If a fluid leak occurs in one circuit, only two of the wheels will lose their brakes and your car will still be able to stop when you press the brake pedal.

The master cylinder supplies pressure to both circuits of the car. It is a remarkable device that uses two pistons in the same cylinder in a way that makes the cylinder relatively failsafe. The combination valve warns the driver if there is a problem with the brake system, and also does a few more things to make your car safer to drive.

In this article, we will learn how the master cylinder and combination valve work. If you haven't read about basic car braking concepts in How Brakes Work, be sure to check it out.

Performance Brake Calipers - 3 Ways To Improve Braking (Besides Red Paint)


Brake calipers

What do brake calipers do?

Brake calipers are crucial for stopping a vehicle, as they house brake pads and pistons that, when activated by brake fluid pressure, press the pads against the brake rotor, creating friction and slowing or stopping the wheels. 

Here's a more detailed explanation:
Function:
Brake calipers are a key part of disc brake systems, and their primary function is to apply force to the brake pads, which in turn press against the brake disc (rotor) to generate friction and slow or stop the vehicle. 

How they work:
When you press the brake pedal, brake fluid from the master cylinder is pushed through the brake lines and into the caliper. 
This fluid pressure forces pistons inside the caliper to move outward. 
The pistons push the brake pads against the rotor, creating friction and slowing or stopping the wheel's rotation. 
Releasing the brake pedal removes the pressure, allowing the pistons to retract and the pads to release from the rotor. 

Types:
There are two main types of brake calipers: floating (or sliding) calipers and fixed calipers. 
Floating calipers: are mounted on bushings and have pistons on one side of the disc, with brake pads on both sides. 
Fixed calipers: have pistons on both sides of the disc, and the caliper itself does not move when braking. 

Importance:
Brake calipers are essential for safe and effective braking, and their proper functioning is crucial for vehicle safety. 

Maintenance:
Regular maintenance and inspection of brake calipers are important to ensure they remain in good working order. 

Signs of a problem:
If your brake pedal feels spongy or soft, or if you notice uneven brake wear, it could be a sign of a problem with your brake calipers.
