Cable Operated Disc Front Brake

#1 PostAuthor: MikeP » Tue Sep 10, 2019 3:43 pm

Gents,

Whilst chatting with Mikey "the mighty polishing god" yesterday I got to look at his hydraulic clutch conversion on his Z1000. It was so smooth and easy and this got me thinking, yet again, to converting the Kwaki triples to a hydraulic clutch mechanism. My only requirement is that the look of the handlebar has to be as per original, ie with a cable lever with the master cylinder hidden under the tank or seat area.

Mikey mentioned that one of the Z1000 had a similar thing with the front brake, which was cable operated but had disc brakes. The question being: which model was it? If you've got a model number and/or have some photos too that'd be grand, and I can get my fag box sketches going. I appreciate I'll have to design and machine the actaul hydraulic mechanism but that's where the fun begins.

Thanks, Mike

Z1r was cable operated to a master cylinder which was in the cockpit fairing :)

the bmw boxers up to 1980 also used a cable operated front master cylinder which was fitted under the fuel tan & clamped to the frame

It was shite, was then, still is, the set up on mine has a neat cut out on the fairing, yes i've toyed with the idea of buying the original bits, Christ knows why though, I can remember my mates one R, it was awful, but back then, back when stuff was plentiful, and Geepeezed stuff was grafted on, it's the red one I put a picture of on here, I still like to stop though, it does help, :D and my setup is simpler, and better than original, why change?

never did rate the braking efficiency of this type of set up on the z1r it was a backward step for kawasaki if they had changed the design of the fairing they could have used a conventional type handlebar mounted master cylinder & probably sold more units

Mike, i think you're onto a good idea, go for it, however shitty the z1r brake set up was; is irrelevant if you're using the M/C for a cable/ hydraulic clutch conversion. i have details of an easy-fit actuator for the push-rod end, and a suitable, modern suzuki remote reservoir stashed in my files if you need any encouragement,just accrued knowledge for when I get round to it, but I'll be using a regular clutch M/C.

Just to throw another option in the ring, Kustom Tech make a quite neat remote mountable master cylinder, which is cable operated.
The unit is quite small & I'm guessing could easily fit under a tank. Obviously you'd have to get a suitable cable made up, but someone like Venhill would be able & willing to help with that.

Thanks to all, Bill, Mark, z1bman and CAT3,

I've started by ordering a master cylinder similar to the Z1R so I can look at the size of actuator cylinder required (as it'll need to be a special design). In tandem I'll also check out the Kustom Tech one as they may have solved problems I have yet to come across.

Wish me luck, and I'll keep you posted.
