Front Brake Master Cylinder/ Reservoir

#1 PostAuthor: Vendetta761 » Sat Jul 13, 2013 7:00 pm

I had my brakes overhauled last year on one of my Sts and the level window in the reservoir has started weeping. I cannot find a replacement kit and even if I could not sure how to fit a new one.
Its a shame as it has leaked brake fluid all over the newly painted master cylinder and clamp.

I think replacing it is the only option but then I saw someone [ possibly a Mk2 project] had fitted a rather trick Brembo (?) front master cylinder with a remote reservoir that looked super small and tidy.
Would this work with standard Z1000 ST brakes and lines, if not what are the other options as if I replace the existing unit with another there is a chance of the very same thing happening again.

Any ideas or spare front brake master /reservoirs handy anyone?

If you want something with a remote reservoir, then a ZX7R master cylinder would work well, should be a 5/8th bore, same as your original........


......... Oddly enough, I might even have one looking for a' new home' :fou

mmm, thanks GB, got any pix? I will do a quick google search to see if I can see what they look like.

I saw a lovely small Brembo unit somewhere, thought it was on the projects forum somewhere but cannot remember for the life of me, is there anyway of saving your favourite threads anywhere /how.

Anyway , interested in the ZX7R one, just had a look on ebay and it looks like just the thing, what would it take to get it to move to a welcoming home, where it will be much loved and used carefully ?

Ok, I've had a good hunt around & all I can find is a m/c with no piston. :roll: You're welcome to that foc, but I can't guarantee it came from a ZX7R.

I have a couple of clutch masters, but no remote reservoir front m/c's. :oops:

ok, Thanks for looking GB, looks like an Ebay hunt for a ZX7 or a GSXR 1000 front master then if I want the small master /remote reservoir look......

Still searching for a spare window seal and method of replacement but I figure the cost of replacement would be the cost of an ebay unit..I will put up a wanted ad just in case, thanks again, V

I will have a look for a gsxr one in the box of bits, it needs the mount I think that attaches the reservoir to the lever. may need the brake lever too but if I can find it you can have it.

Fitted a Suzuki GSXR1000K2 front master cylinder /remote reservoir to my Z1000MK2 works well & looks the part.

ive got a gpz900r which had a crazy / cracked sight glass on the clutch master cylinder, i ended up pushing the plastic one out and getting a piece of watch crystal the correct size to fit in its place, £5.00 of a local market trader in town. I used silicone to seal it in, so far so good about a year on
