Rear Master Cylinders

Harley-Davidson rear master cylinders are available in model-specific and replacement configurations for a wide range of motorcycle braking systems. The range includes complete Harley-Davidson rear brake master cylinders, remote-mount master cylinders, billet designs, chrome and black assemblies and replacement units for both modern and older Harley-Davidson applications. Harley-Davidson service information identifies the rear master cylinder and reservoir as serviceable components and lists related rebuild kits, reservoir assemblies, gasket kits, push rods, yokes, mounting brackets, banjo hardware and other supporting components.

The product range includes Harley-Davidson rear master cylinder rebuild kits, pistons, O-rings, reservoir gaskets, cover gaskets, rubber boots, filler caps, reservoir assemblies, support brackets, mounting kits and replacement covers. Bore sizes such as 5/8-inch and 3/4-inch are represented alongside remote-mount and traditional master cylinder configurations. Applications cover Sportster, Softail, Dyna, Touring, FL, FX and other Harley-Davidson models, with products from V-Twin, Drag Specialties, Harddrive, Colony and Cycle Pro providing options for replacement, restoration and brake system service.

Correct fitment is especially important for Harley-Davidson rear brake master cylinders because mounting style, bore diameter, reservoir configuration, brake-line connection and model year can vary between applications. Some products are complete assemblies while others are individual rear master cylinder repair parts, allowing specific worn components to be replaced without replacing the entire assembly. Harley-Davidson service documentation also identifies separate reservoir covers, gasket kits, mounting brackets, push rods and rebuild kits, reinforcing the need to match each component to the applicable rear brake system and motorcycle configuration.
