1981 CB750C Front brake pistons.

The whole gambit, on the dust boots for the slider bolts. The piston seals and dust covers fit perfectly.

I know what you're saying, the rubbers that go on the slider bolts, 1 on each end of the bolt and 1 on each side of the mounting bracket. did you check that site I posted to see if they sell those boots?

[shinyribs]

I didnt check for just the boots alone. I need to do that. Thanks for reminding me

shinyribs: where did you buy your caliper rebuild kit(s)?

[shinyribs]

They came from VintageCb750.com      Trying to remember the brand cuz i have seen that brand on ebay,so you might be able to buy them cheaper that way. Tourpak?...tourkit?...tour-something , i just cant remember right now. I'll be in the shop later and will check.  


Too bad i cant tapatalk a pic of the box right to here

Yeah, I checked them.... Interesting thing... I actually bought rebuild kits from them for my 81/F. Tried to get away without replacing the pistons. Anyways.... If you look up the PN for the 81/F kit vs the 78/F like you described, same PN. So I swapped the guts over. The pistons are also the same diameter, but shorter length. I bring this up because the calipers on my 81/F do in fact only take two rubber boots. On my phone right now so I can't upload pics, but I'll try to get some online later to more clearly show to why I'm talking about.

there is a REAR rebuild kit for my 80k but it only comes with two shaft boots and i need 4 for the front caliper. i don't want to have to buy two rear kits just to get the extra two shaft boots!  :0  but it seems i may unless i come across an 80k front caliper rebuild kit.  

will this piston fit my front caliper ? the other link doesn't send to Canada :(

i also noticed when taking my brake pads out that there was no shim on the piston side pad. is this a big deal ?

In case anyone else comes across this I found some that I installed on my 81' CB750 C that worked a treat:
