Brake Caliper Rebuild Kit - Honda CB450K 1970-1971 - CB750K 1969-1976

Reproduction brake caliper rebuild kit for the CB450K 70-71 and CB750K 69-76. This is a great kit if your piston is pitted and needs to be replaced. Brake effectively and ride safe with a new piston!

Kit Includes:

Piston: 45107-300-003 - Diameter 38.13mm / Height 34.15mm
Piston Seal: 45108-300-003
Bleeder Valve: 45109-300-003

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 hollow side of the piston 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)

We also carry a version of this kit with the caliper. Make sure your caliper is stock, the CB450 changed it's caliper in 1972 and the CB750 changed in 1977.

Fits Honda:

CB450K - 1970-1971
CB750K - 1969-1976
