Reproduction front brake caliper rebuild kit for the Honda CB750. Replace the piston seal when replacing your piston or after cleaning the stock piston. Forms a tight seal to prevent brake fluid from seeping past the piston.
Note: This fits on the stock caliper with 50mm (2") spacing between the mounting bolts (measured center to center). There is another very similar looking caliper that was used on earlier models from early 70's.
Kit Includes:
Piston: 45107-392-003 - Diameter 43mm / Height 34mm
Piston Seal: 45215-533-004
Bleeder Valve: 45224-579-013
Bleeder Valve Cap
Installation Tips:
Make sure to thoroughly clean the channel in the caliper that holds the seal, if there is any built up grease or dirt it will not allow the seal to sit properly which will affect the pistons ability to engage and retract.
The darker side of the piston with the indented ridge faces the brake pad.
Use brake grease between the piston and the pad but do not allow any grease or brake fluid to come in contact with brake pads. (this kit does not come with pads)
Fits Honda:
CB750A - 1976-1978
CB750F Super Sport - 1975-1976
CB750K - 1977-1978

I ordered this for a different make of bike. The piston is what I needed but the bleed screw isn't compatible with my model.
