| 150 psi would launch that puck thru a wall, be glad it didn't come out! block the hose inlet with a plug and use the bleeder valve as a grease zerk |

So even with that kind of pressure and no luck I should still try with a grease gun? What do you mean by grease zerk and what would I use to plug the hole with?
Anyone know about the 750 caliper? |

| find a plug or bolt to match the threads in the hose fitting hole screw it in gently doesn't need to be real tight but as many threads in as possible, a zerk (grease nipple) is what you put a grease gun on, the tip of the bleeder valve acts just like a zerk, pumping it out with a grease gun it won't pop out since you can't actually build up pressure with grease it will either move the piston or you won't be able to pump the grease gun |

Au contrere, mon frere. If you've got it sealed tight and you're squeezing like hell on the grease gun handle, you can put more than 1,000 pounds of pressure into that thing if the puck doesn't move first. Air is compressible, grease isn't. Use caution with the grease method.

Sorry to bring this back up but I have an update...
Just got a caliper from a guy who said that it was working on a bike before he took it off to send to me. well I got it and there is still brake fluid in there but I couldnt get this one to budge either. I put about 100psi into with a rubber nozzle and nothing. Tried the grease gun method but it just leaked out the plug and was making a mess.
My question is how long at 100psi should it take for it to move, I only held it on there for 10 seconds tops with no results. There doesnt appear to be any rust around the edge of the brake pad like in the others I have that are locked up. Would hooking it up and trying it do any good or if 100psi doesnt move it it is stuck?
Thanks for all your help with this, this is the 2nd "working" caliper I have gotten and they are stopping me from having a road worthy 350 which is making me a little frustrated. |

Try Grease method but put several wraps of teflon tape on the plug first... that will stop it from leaking
Don't feel left out either, I will be doing this myself next week as I just bought a "working" assembly off ebay that I am sure is not going to "work" when I get it. I will let you know if I have to do anything special or figure out any new tricks. |

Does anyone know if a 78 cb750 caliper assembly is compatible? |
Who knows??
You never told us what year/model you have. Should have been in your first post, dude.........
In general, any single-disk Honda master should work, but there are exceptions.
Without knowing what bike you speak of, it's impossible to say.........
Most Honda calipers are specific to the forks/wheel/fender setup......

Sorry its for a 73 350.
Anyway used the grease gun method today with some teflon tape worked like a charm and I got two unstuck and will probably try the third one I have in the next couple days.
So if anyone needs a 350 front brake caliper let me know now.
Thanks everyone for your help and patience. |

Thank goodness I work at a camp that pretty much has its own shop in it complete with clean up sink that made cleaning them a breeze.
Let me know if you want one, it looks like ill have one or maybe two to sell depending on if I want to hold onto one or not. |
