In brakes we call this brake fluid of which there are a few different varieties, but more on that later. As is common in hydraulics the initial force which is applied to operate the system is multiplied in the process. The amount of multiplication can be found by comparing the…show more content…
The entire braking system can be broken down into the following main parts: 1) Master cylinder (Lever) 2) Lines 3) Fluid 4) Slave cylinder (Caliper) 5) Pads 6) Rotor  Master Cylinder The master cylinder, mounted to the handlebar, houses the brake lever and together they produce the input force needed to push hydraulic brake fluid to the slave cylinder (or caliper) and cause the brake pads to clamp the rotor. The lever stroke can be divided into 3 categories: 1. Dead-stroke: - This is the initial part of the lever stroke when the primary seal pushes fluid toward the reservoir before it goes on to push fluid on to the calliper via the brake lines. 2. Pad Gap Stroke: - This is the part between the calliper beginning to push the pistons out of their housings and the pads contacting the disc (as the dead space between the pads and rotor is taken up). 3. Contact & Modulation:…show more content…
Modulation is rider controlled and not necessarily a characteristic of the braking system, however some brakes may allow the rider to better modulate or control the braking forces than others.  Brake Lines Hydraulic brake lines or hoses play the important role of connecting the two main working parts of the brake, i.e. the master cylinder and slave cylinder. We've already mentioned that hydraulic systems can be very versatile in that their lines or hoses can be routed almost anywhere so let's take a closer look.  Hose Construction Hydraulic hoses are multi-layered in their construction and usually consist of 3 layers: 1. Inner Tube: - This layer of tubing is designed to hold the fluid. Teflon is usually the material of choice here as it does not react or corrode with brake fluid. 2. Aramid (Kevlar) Layer: - Provides the strength and structure of the hose this woven layer is flexible and handles the high pressures of the hydraulic system efficiently in that it should not expand. Kevlar is also very light, which is a desirable attribute for any cycle component, and also it can be cut easily and re-assembled using standard hose fittings. 3. Outer Casing: - Serves as a protection layer for both the Kevlar layer and the bike frame to reduce
