Reproduction brake caliper rebuild kit with a stainless steel piston for many of the 70's Honda CB's from the 350-550. 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:
Stainless Steel Piston: 45107-323-020 - Diameter 38.14mm / Height 34mm
Piston Seal: 45108-300-003
Bleeder Valve: 45224-579-013
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 side of the piston with the 2mm outer lip, faces the brake pad. Some pads come with a plastic ring that goes between the pad and the piston, it helps the prevent brake squealing.
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.

Great
My 77 CB550K had brakes that were dragging really bad. Popped the old piston out, cleaned the sludge and used this kit. Now my brakes work great. Took me about 30 minutes with no prior experience. Highly recommended!
