Master Cylinder: Disassembly
- Remove master cylinder cover and diaphragm, and drain fluid from reservoirs. Stroke piston to force residual fluid out through outlet ports. Remove piston stop bolt from housing, and remove retainer ring from groove in end of cylinder bore.
- Remove both piston assemblies, then remove any internal parts remaining in cylinder bore. Remove and discard all rubber parts from piston assemblies.
- Enlarge hole in tube seat using 13/64" drill. Tap out seats with a 1/4" x20 tap. Install spare tube nut in outlet hole. Place a flat washer on a one inch long 1/4" x20 screw, and thread screw through tube nut into seat. While holding screw to prevent it from turning, back tube nut out of outlet. Remove residual check valve and spring from outlet.
