Z1R Front brake reservoir

Postby ianp » Mon Dec 05, 2016 5:40 pm

Hi guys,
I have a leaky front brake reservoir - seems to be leaking through the join.
Anyone know what I can use instead - these seem to be extremely rare items - I've been looking for a while...
Been looking at these - maybe they can be made to fit somehow? Is the hose that goes to the master cylinder 5mm (3/16) or 6mm (1/4)? Assume this one takes the 6mm hose.

Cheers,

Heh Ian, What do you mean "join" ?

If the outlet is larger (9mm lip) you could look for a reducer to your hose size. Can you measure it?
I have an '77 Z1R too so am interested in how it goes.

Cheers, Rossco

Sorry Rossco66 - I hadn't spotted your response...

Anyway, I managed to score another fluid reservoir which stopped the leak.

I also scored another set of calipers, master, cable and lever from what must be a later model Z1R.

There are 2 differences - firstly the pistons are 42mm rather than 38mm (a 22% increase in piston area by my maths) and secondly the master cyclinder actuating lever is different - the later one has an offest pivot point (the earlier one being in the centre).

I've yet to test properly but it early signs are that these brakes are a huge improvement over the earlier ones!
