I don't recognize the looks of those rotor centers, I think they are aftermarket. Not sure if they are EBC though, but they are unfamiliar looking. If they fit the model stated, then they should work.

hi Dan you got any brackets in stock for the brake upgrade? for my 1978 GS750?

Your pictures will not enlarge, not sure how you posted them, but zooming in to the very fuzzy thumbnail pictures, they look like opposed-piston 4-pot calipers, which will not work so well for this because the vintage wheels are wider in the spoke area. Also, those calipers are not the style that the brackets being sold in this thread are designed for.

They must have the reversible steel mounting bracket with the lightening holes drilled into it, and two pistons on one side of the caliper only, one larger than the other. Look up a 1989-1996 or maybe 1999/2001 Suzuki GS500 caliper.... if a caliper looks just like that, then it will fit. The GS500 will only give you one side, you need dual disc. So look for a Concours Kawasaki, some ZX 1100 ninjas, some zx600 Ninja if I recall, or a GSX 1100 G Suzuki. There should be a fairly comprehensive list somewhere in this thread that tells you what donor bikes are good to get the calipers off of. If hunting single calipers, early EX500 ninjas have a left caliper, later EX500 ninjas have a right caliper, or vice versa.

Hi Guys just uprated my engine 1978 GS750 - 840 now i really need to uprate the front brakes so what will i need for the job? I'm in the UK

Good stuff. You can use 6 Stock Suzuki or Kawasaki caliper bolts with a fine thread nut behind. That's generally what I do.

Dan

I looked at that, thought they looked short for the nut, will recheck that.

Does anybody want a full set? Concourse calipers (about as new as you can get) in great shape, silver color.
Need new pads as they are right on the wear limit.

F3 rotors
Can include the additional M10 bolts & nuts needed if required.

[QUOTE=salty_monk;2460016]That's correct. I try to find a flange nut if possible or a thin nut with a washer. You don't want too much thickness back there as that is the closest point to the rotor. Fine thread & blue loctite are a good idea.

I will try to post some better pics on page 1 again but you can see a bunch of them here http://s6.photobucket.com/user/salty...700258&page=11 also on page 2 & page 12.

Cheers,



Thanks.


That's what I figured, but easy to ask first.

So far it all looks good, just have to find some nice bolts now.

Hey Dan

Re your brake kit.

The lower mount/hole on the fork leg , does it get a nut on the inside?
It's not a threaded hole.

Wish the pics on page 1 were still there.

Thanks
