Ok so does anyone know if fitting a T4 master cylinder would work with running a set of HiSpec 4pots on the front and standard rear brakes?

Reason for this is my master cylinder is dead and I can’t seem to locate a replacement

I've had hispecs run on standard MC with no issues. I used a 25mm VW on 330mm brembos. I have a good standard master I can supply.

Fittings needed for a t4 are m12 Btw, when I ordered mine the website said m10.

the t4 m/c abs version has 2 ports which are M12 fittings as craig has said above. there is a 4 port non-abs version which has M10 fittings and it can be used without messing around with the shape of the fluid reservoir, just plug the holes of the other side.

Yeah I’m not all the worried about the way a T4 master cylinder fits what I’m more interested in is if it would work with the 4 pot calipers and what the peddle would be like

the m/c should work fine with the calipers. the pedal should be firmer with less travel i believe.

Perfect thank you 👍🏻 I’ve managed to get hold of a standard second hand item but if that doesn’t work I’ll go with the T4 one. Thanks for your help

Bit late to the party but I run the VW one on mine and the pedal is pretty solid, that's with the 310mm kit. I used the 2 port version which required a bit of flexing the reservoir but nothing drastic

As far I understood the easiest way to delete the ABS is with 7D0611019A.Can I attach the original reservoir?
