Reproduction Front Brake Caliper Piston - 45107-300-003 - Honda CB450K CB750K

Reproduction piston for the front brake caliper. These fit 2 years of the CB450K and CB750K's from 1969-1976. Replace your piston if it has pitting. Brake effectively and ride safe with a new piston! Sometimes even after cleaning the piston and caliper the piston doesn't retract properly, make sure that the pads aren't rubbing after installing new brake parts. This piston fits into the stock caliper or a replica caliper. Make sure your caliper is extremely clean and smooth before installing a new piston.

The hollow side faces the brake pad.

We suggest replacing the seal at the same time.
