How Do You Rebuild A Harley Master Cylinder?
Harley-Davidson master cylinders (m/c) are a crucial component to the safe operation of the motorcycle. The m/c houses the piston assembly and the brake fluid reservoir. When actuated by the hand or foot lever, the piston pressurizes the hydraulic system which then acts on the caliper piston, causing it to clamp the brake pads onto the brake rotor. This action converts the rotation force into heat energy, which is dissipated by the rotor. The rubber seals on the piston are prone to failure over time and are considered a critical wear point that must be repaired occasionally. Remove the hydraulic line from the m/c and discard the crush washers. Remove the m/c from the bike. The rear m/c may be simply unbolted from the frame. The front m/c must have the pivot removed from the assembly. Remove the snap-ring from the pivot and draw the pivot from its boss. Remove the hand lever from the m/c. Remove the reservoir cap and dump the brake fluid. Inspect the reservoir for silt or debris and was
