'77 CB750K caliper question

Hey guys...

I'm looking for the caliper rebuild kit. I found a ton of them for the '77 750F but none for the K model. I know the F is different from the K but why is the K so hard to find?

Was it the same exact brake for the '75 and/or '76, ie, can I just use that?

Thanks guys!

Is there a reason for the rebuild kit? Is your piston really corroded and pitted? If not, the square o-ring is all you really need and honda should still have those. That is about all you need to the caliper. If you need a piston, you can find them on ebay. Get the phenolic style if you can.

I have rebuilt several, and never needed to replace the O-ring. I just clean the grove, and the inside of the caliper with a brass wire wheel on my dremel tool. Do not use a hone on these. Also I have only once replaced a piston. Got it from ebay. Was pricy, but a very nice product.

I replaced mine as it was the original and almost 30 years old at the time. The new one was under $3 when I got it so it didn't hurt the wallet too much.

Thanks guys! I actually just got the bike a few weeks ago. My dear old Dad was nice enough to go pick it up for me (in Toronto). I live in Montreal so I actually haven't even seen her in person yet. I'll likely just take the caliper apart and hope a good cleaning will work. It just seized apparently, most likely cause it's been sitting for a while.

When you go to remove the piston, take off the caliper and squeeze the lever to pop it out into a bunch of paper towels.

But that is not as much fum as using an air compressor, and blowing it through the garage window.

Well this is true but window replacement sucks!
