No problem installing. Works fine. CB400F1 1976
Replaced OEM caliper on a Honda CB400F1, 1976 year model. Old caliper was stuck. I had no issues installing the replacement caliper. The OEM brake hose fit perfectly. No problem bleeding the brakes. The pads appear to be good quality and stop the bike just fine. Note: The Clymer service manual says to remove the front wheel to replace the caliper. That's not true. Just takes getting the spokes lined up to get the caliper out and back in.

3 different M Mati calipers for Honda MC leaked
I have ordered three of the M Mati calipers for a 1971 Honda CB500 I'm working on. They all leak at the caliper pipe connection ALL of them. With each attempt I installed new lines. Great care taken to first finger tighten to avoid cross threading. Every time I would attempt to bleed the system once a little pressure was introduced that connection at the caliper would leak.

Perfect fit
Much easier to replace the caliper than trying to free up the old one. Only catch was the cotter pin supplied was a little big. Everything else works perfectly.

Pretty bad casting quality but functional
The casting quality on the caliper itself was pretty bad and I decided against putting it on my bike just because of the numerous visible flaws. That said I’m sure it would work fine in a pinch. It also had a ton of paint drips and overspray that had to be sanded off before the pads would even fit in the caliper which was annoying but not the end of the world. I ended up cleaning up my original caliper and using the piston, O ring, bleed screw, and brake pads from this kit to rebuild mine and all those parts were good quality and have worked great so far. All in all 6/10, it’s about what you would expect for the price and I’m sure is perfectly functional but very much lacking on the quality of imagine you could get from a slightly more expensive kit.

Good caliper, but not OEM quality.
Fits well, and works good. The piston is hollow, which is a bit of a bummer. It means that you can’t use the nylon ring on the brake pad, and they might squeal.

Not a bolt on part and doesn’t sell individual pieces
This caliper has different mounting hole spacing so you will need to buy the complete kit with mounting arm also. Doesn’t line up with any Honda factory parts other than the brake pads.

the flange fitting was not machined properly therefore could not stop from leaking. Throw away
