<P> The most common vehicle uses of master cylinders are in brake and clutch systems . In brake systems , the operated devices are cylinders inside brake calipers and / or drum brakes ; these cylinders may be called wheel cylinders or slave cylinders , and they push the brake pads towards a surface that rotates with the wheel ( this surface is typically either a drum , or a disc , a.k.a. a rotor ) until the stationary brake pad ( s ) create friction against that rotating surface ( typically the rotating surface is metal or ceramic / carbon , for their ability to withstand heat and friction without wearing - down rapidly ) . In the clutch system , the device which the master cylinder operates is called the slave cylinder ; it moves the throw out bearing until the high - friction material on the transmission 's clutch disengages from the engine 's metal ( or ceramic / carbon ) flywheel . For hydraulic brakes or clutches alike , flexible high - pressure hoses or inflexible hard - walled metal tubing may be used ; but the flexible variety of tubing is needed for at least a short length adjacent to each wheel , whenever the wheel can move relative to the car 's chassis ( this is the case on any car with steering and other suspension movements ; some drag racers and go - karts have no rear suspension , as the rear axle is welded to the chassis , and some antique cars also have no rear suspension movement ) . </P>
