Crown Brake Master Cylinder – BP-1424

Crown built this brake master cylinder for its lift truck line, where it converts the force of the operator's brake pedal into the hydraulic pressure that actuates the wheel brakes. The master cylinder is the heart of a hydraulic braking circuit: its internal piston and seals pressurize the brake fluid, and worn seals or a scored bore show up as a soft, sinking, or fading pedal.

Weighing 5.5 pounds, it mounts as a direct replacement for the failed unit on the Crown truck and restores firm, consistent pedal feel once the system is bled. A master cylinder that leaks internally or loses its seal lets pressure bleed off under a held pedal, the classic sign the unit has reached the end of its service life rather than a fault elsewhere in the lines. Because bore size sets the pressure and fluid volume the cylinder delivers, match the bore of the replacement to the cylinder coming off the truck before installing it.
