HYDRAULIC BRAKE SYSTEM OPERATION Typical Hydraulic Brake System Must be clear to allow proper diaphragm movement Compensating
friction reduces brake disc and vehicle speedAs the lever pressure is increased, the braking affect is also increasedThe
friction applied to the brake pads will cause the pads to wearAs these pads wear, the piston within the caliper moves further
outward and becomes self adjustingFluid from the reservoir fills the additional area created when the caliper piston moves
outwardBrake fluid level is critical to proper system operationToo little fluid will allow air to enter the system and cause
the brakes to feel spongyToo much fluid could cause brakes to drag due to fluid expansionLocated within the master cylinder
is the compensating port (C) which is opened and closed by the master cylinder piston assemblyThe port is open when the lever
is released and the master cylinder piston is outwardAs the temperature within the hydraulic system changes, this port compensates
for fluid expansion (heated fluid) or contraction (cooled fluid)During system service, be sure this port is openDue to the
