Topic: What other year front brakes caliper/rotor will work on a Cb750K3???

[mylittleho]

The junk yard bike I have is almost 100% complete.. it was missing a headlight (which I now have) and the front brake caliper, bracket, rotor, and brake like.. Are there any other year brake caliper, bracket, rotor and like that will work??? I have been looking on Ebay and I see brakes for sale (god they are going for some major $$$$$) but I never see any for a 73 was wondering if any other years were direct replacements...

I am pretty sure that the k3-k6 front brakes are the same and will bolt on your fork legs and work. Better to get the whole setup than piecemeal it. Have you called local bike shops and asked what they wanted for calipers? Have you called clancy's and see if he isn't flodded out and what he may want for one?  If it isn't a resto, you don't have to use a stock master cylinder (a more modern one might improve your braking slightly), you just need one that takes the same banjo bolt.  The rotors should be the same for k0-k6 but I think the caliper is different for earlier bikes.

Hey guys I do know that 69 on up to 76 caliper will work in 77 they chamged them only down where the puck goes into the caliper cant see it not apart its the little peton that screws into the left puck side of the caliper (sitting on bike) that little thing slides in a groove after 78 they chamged them they have a groove on the puck not on the caliper now ;ike someone else posted use the whole thing off a 77  78 and that will work  make sure to center the caliper  when all bled  good luck 750 four ever

The 750 calipers are all the same for the K0-K6, but the forks, and mounting bracket (referred to as the caliper holder joint in the parts manual) changed in 1973. If you have the early forks you must use the early bracket. If you have the later forks you can use the F/F1 bracket, arm(referred to as caliper holder in the parts book) and caliper. The F1 has a slightly larger piston and hence slightly better braking.
An F1 caliper will not fit on a K3-K6 arm, so you will need to buy the arm as well.
The early brackets are often referred to as the 'C' type and the later brackets as the 'T' type.
The K7 and K8 are the same as the F/F1, but the F2 are very different
Post a photo of your forks if you want definite identification
Hope this helps
