Front brake master ,,, ??

Front brake is bled and solid ,, but lever is almost coming back to bars before brakes work ,, the brakes work ok ish but something is not right ,, NEW pads all round , all pistons working ok ,, its almost as if the brake piston rod is not enough travel or too short ...

Master cylinder not leaking or losing air ??? it is 24 year old so might benefit from a rebuild kit or a replacement ,, what is cheapest replacement ?????

Both unobtainable in Thailand unless I buy some Chinese after market one ????

OK problem solved bought a Brembo RCS radial kit ,,its probably a Chinese Fake but it looks well made and now the front brake is perfect ,, the old Master was 16mm and new one is 19mm but all is working well.. Had to mount throttle cable outlet on top to clear the RCS as it sits closer to the twistgrip so really need a throttle cable about 3 inches longer ???? but I have got the old one working for now

cant fit mirrors to RCS so may have to look at using bar end type ???? or no Mirrors



what other makes use throttle cables with 8mm thread into twist grip , ??Honda, yamaha ??? as im looking around here ...

also now I will get a matching Radial clutch master of same type will send some photos soon

I have an RCS brake master on my Guzzi, with a mirror;







You just need the replacement clamp that sits around the bar, like this;

Aftermarket; https://www.carpimoto.com/en-GB/4817...r-Cylinder.htm

That looks a dead ringer for the standard vertically split clamp for a coffin master. I bet one would fit.
Not sure if they are any more plentiful or as cheap as the ones you linked to though?
You must have those on your M750 Jerry? Worth a look to see if they would fit.
(SS would not have mirror bosses.)

Not familiar with the coffin master but I think most Brembo stuff is likely to be compatible so they should be widely available.

Do you have a link for the RCS masters Jerry? Been considering some but for the cost. Thanks

This is for the S4 in Thailand not M750 type coffins

I know.
I was suggesting that coffin clamps would fit your RGS GTI Fandango radiant pumps so you could mount a mirror. If you have any spares.
