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 high temperatures created within the system during heavy braking, it is very important
that the master cylinder reservoir has adequate space to allow for fluid expansionNever overfill the reservoir! Fill to 14,516,
