Complete Honda front brake caliper assembly. This caliper assembly does not come pre-assembled, it includes all the parts shown in the photo.

This presents a solution to these questions...."what do I do if my piston is heavily pitted and so is the inside of my caliper?" or "my pads are toast, my bleeder valve is seized and so is my piston!" Yes, some of us just start cleaning, soaking and scrubbing all the parts and replace individual parts such as the piston, seal and bleeder valve but if you want your caliper looking and working like new and you want to save a lot of time, get the complete caliper. Finish the job in minutes rather than hours!

Complete Caliper Assembly Includes:

2 - Mounting Bolts - 90165-323-000
2 - Washers (for mounting bolts) - 94102-10000
1 - Cotter Pin - 94201-16220
1 - Rubber Cap for bleeder valve - 45225-579-013
1 - Piston - 45107-323-020
1 - Bleeder Valve - 45224-579-013
1 - Piston Seal - 45108-300-003
1 - Pad A - 45105-390-305
1 - Pad B - 45106-390-305
1 - Caliper A - 45101-323-013
1 - Caliper B - 45102-323-003

Honda OEM Part Number: 45100-390-405 Installation Note: If there is any black paint over-spray inside the caliper it should be removed with brake fluid or an equivalent solvent prior to installing. Some steel wool will clean it up easily.

    Easy swap, went from stuck front slave cylinder and sketchy brake to great stopping power and smooth operation. Nice quality piece.

    Great sub for OEM

    Posted by Gene on 28th May 2018

    This brake caliper kit was the perfect replacement for my rider-quality CB350F restoration. I tried cleaning, rebuilding & painting my original caliper bur sadly it was too far gone and ended up leaking around the piston and line fitting. This kit from 4 into 1 works great and looks period correct.
