    Fixing up a friend's 1992 CB750

    Hi all, I'm a Suzi/Yamaha guy but am repairing my friend's '92 CB750. Its the usual sort of thing; he bought the bike in good shape, parks outside uncovered all the time, infrequent maintenance, rides it only the good weather etc. I rescued the bike when it wouldn't start and left him...

    1980 CB750F Brake parts

    Hi all, I just acquired a handsome 1980 CB750F. The rear brake was seized which I had assumed was the piston. Turns out the piston is fine and I'm ready to rebuild with just new seals; easily obtained. What is of concern is that it was missing the brake pad shim and brake pad spring. Both of...

    Bleeding the twin piston, twin caliper front brakes. CB750 F 1983.

    Having reached the stage in my rebuild of fitting the front brakes I ran into problems bleeding the air out. Rebuilt calipers, new pads and new braided brake lines. Following the manual(s) resulted in a very soft brake lever, several attempts at bleeding produced no improvement, the lever almost...

    Emptied master cylinder, still need piston out, next steps

    N00b here when it comes to brakes. I have a caliper that seems to misbehave after braking once or twice - piston gets jammed, have to wait until it slowly goes back in. I figured a rebuild would be a good idea after asking around and would be interesting. Long story short, master cylinder is...

    Hi I'm Tommy. I live in the Lehigh Valley in PA. I recently acquired a 1978 CB750F with 30K miles on the engine. The bike hasn't been registered since 1984 and the engine turns over with the kick start without a problem. My friend was saying "just do a compression test and if it's good then go...

    Remove front master cylinder Oil Cup 45511-463-006

    Hey, How does this come off? Is it just an O ring holding it on after removing the 4 cap screws? I can't see any other fasteners down inside the cup. The part drawing at Ron Ayers doesn't show any other screws. What am I missing? Confused, Al

    Front Brake Help

    Hey everyone, So my front brakes to my 1978 Honda cb750k need to be redone, due to the piston ceizing itself within the caliper. I have tried everything to get it out but it won't budge, so I'm moving on. Brake calipers are very pricey if they're original, even used. I was curious if there was a...

    Looking for help replacing front brake pads

    Dual Disk Upgrade

    First post from a new member here. I thought this may be the obvious, best place to get advice on a first time Cafe build I am starting with a 1980 CB750 Custom. This came with a single disk front brake. I prefer the look of the dual disk, so I went on eBay and bought a set of forks, c/w triple...

    A call for help here.

    I'm in Oaxaca, Mexico with my 2003 CB 750. Brake pads were new in Chicago and okay in San Francisco. Now they look shot. Did have presence of mind to bring a spare front set. Question: What tools do I need to make this happen? Pop off the plug and a screwdriver enough?? The whole story is...

    80 cb750c caliper mounting bolts

    I have a 1980 cb750c that the front caliper locked up on the po, so they just removed it from the rotor and ziptied it to the top of the fork. Lol. I have pulled the caliper apart and I am rebuilding it. But, the two mounting bolts that hold it to the fork are missing. Can someone point me in...

    Replacement brake rotors

    Doing some quick reading, seems a lot of people blame the dreaded brake squeal on the stock rotors, the material they are made from and the fact that they are not slotted. Has anyone actually just replaced the brake rotors as a method of remedy? I found these on Amazon, but only have one...
