    Need help with brakes

    Hello everyone, I'm relatively new on the forum and I'm writing from Serbia. Recently (well not so recently, in the autumn :) ) I came into possession of an CB750 C (R6) and I have been slowly rebuilding it. So far everything went well, however I can't identify the brake pads. I have contacted...

    Can't Lock Front Brakes

    Hi everyone, I recently got a newer sport bike, and it made me realize how truly awful my front brake is on my '78 CB750F. Only squeezing with my index and middle finger, I can barely build any brake pressure. Using all four fingers, I can stop, but I can't lock the front brake. And since I can...

    Steel braided brake line

    I'm looking into replacing the original front brake line on my '79 and I figure I'm gonna go braided stainless steel while I'm at it. I've found a couple options online but I figured I'd make a post to get some opinions on them. 1. Carpy's cafe racers. This one seems good and it's the one I'm...

    low brake pressure - bleeding the brakes wrong?

    obligatory 1978 cb750k I got this bike about a year ago and finally got it up and running this spring. I’ve been riding it around town and to work and such, no apparent problems with the brakes. About a week ago I found out the brakes weren’t in tip top shape when I needed to stop very...

    hello CB750 friends - in the proces of resto-modifying ( into a race replica ) my CB750F s/s, like most of the bike ... the rear brake's master cylinder is completely gone -- I had to cut it off from the footpeg brackets, since it was welded by years of galvanic corrosion so my question is...

    1995 Rear Brake Pedal replacement

    Hello all, I have done a little searching, but as of yet, I obviously haven't found the info I was looking for. I am a new rider, and make a mistake while changing the oil. Needless to say, I dropped the bike, and bent the rear brake pedal. It's still operable, but the pad is angled at an...

    Master Cylinder

    I am trying to get the master cylinder reservoir off the base. It is the plastic one with the 4 screws to hold it in place. I removed the 4 screws and tried to pull it out. It will rotate quite freely but it refuses to come out. It looks like there is two rubber "O" rings or seals that is...

    CB750F1 Torque Link Hardware and Other Questions

    Hello everyone, I recently bought a 76 CB750F that is, unfortunately, missing some important hardware. I am missing parts 48, 28, 63, and 62 in the first attachment. These parts are the mounting hardware for the rear caliper torque link. I'm missing that hardware for the front mount and I can...

    Help with front caliper

    Just purchased a 1977 CB750k. It's in pretty good condition other than the fact it has been sitting man years. I've got it running pretty well but the front brake was not functional. Rather than chase the problem down part by part i replaced everything from the master to the hoses to the...

    Rear Master Cylinder Hose

    Hello all, I'm a fairly new wrencher and am trying to replace all the rubber seals and hoses on my 1980 CB750F. The one that's causing the most grief in finding is the reservoir hose for the rear master cylinder...I'd like to replace it with braided stainless. I can't find specs for the proper...

    1979 CB750F front and rear calipers

    Does anyone know if any other model calipers will work with existing mounting holes on front forks? or existing caliper brackets? like perhaps the 900C from the 1982?

    Rear master cylinder

    Hi all! I have a 1972 Rickman. I’m the second owner. When I got the bike a few months back, both the front and rear brakes did not work. In fact, they were both dry as the bike had sat for about 7 years. I rebuilt the front master, and cleaned the calipers. The front now works as it should. I...

    73 CB750 caliper MC help!!

    Rebuilding the MC as it was original. Ordered a rebuild kit. Then a second one because I thought I made a mistake. Both came in with a smaller diameter kit than what is on the bike. Plunger was about 1MM smaller. Could this be because the MC came from an older model and used anyway at the...

    Front Brake Lever Piston / New Brake Lines

    I'm getting closer to to road ready on a '82 CB750 Custom. The previous owner had let the bike sit, but his brother installed a new plastic brake reservoir on the brake lever and gave me all new front brake lines (all the way down to the calipers). Installed those, but their full of air at the...

    1980 cb750k drum brake problem

    Replaced the brake shoes on my rear drum as part of rear wheel service, (all new bearings to) all went together fine. This is on a bike I have been restoring for the last 2 months. Finally took it out for a short ride, motor still needs some tuning but all in all it ran pretty good. Had to...

    1982 F2C brake rotor upgrades

    So I'm looking to do a few upgrades to the brakes on my F2C. The current rotors have seen better days (as you would expect for an 30+ year old chunk of metal) and rather than just opting for some OEM replacements that will also be used, i was wondering - does anyone have any...

    Hello everyone! I have just got myself a CB750F Boldor 1982 that I will try to give a scrambler look. To do that I would like to fit a knobly rear tire. But how large (wide) can i go?

    Recommend a brake disc drilling service?

    Considering having all three rotors on my 81 750F drilled and want to see if there is a recommended machinist/shop that performs this service. I did a minor build on a 900F in the late '80's and sent the rotors out for drilling and really enjoyed the looks and performance. I recall back then it...

    Front brake pads make scraping sound

    This is a 1980 750C. I removed my front wheel in order to take off the fender so I could paint it. When I removed the front wheel, I did not remove the brake unit as I just needed enough clearance so I could get my wrench on the fender bolts. I just removed the axle holders. After putting...
