Believe this is the list of master cylinders from the key manufacturers which are a direct replacement for standard one when fitting 4 pot brakes.

23.8mm bore 4 x 10mm connections.

Cheers Evo. Could come in handy if I ever decide to try changing the master cylinder on mine. Do you have a 23.8 bore one on yours? Have you experimented with any other bore sizes?

Got one from a local factors today (not a big brand name) but should work. Will confirm tomorrow.!!! 19mm one causes a long pedal.

Got the 23.8 in combination with grA 4pots (280mm rotor/bells AP's). Works great, 20mm was like a sponge.

great link btw, thx.

Does anyone know where the thread about 4 pots & master cylinders is :?: The 1 that gives you the equation to work out total piston area of the calipers and the master cylinder, been trying to find it for bloody ages :evil:

Would this be over kill on a standard set up. Cant help but feel the standard set up could feel better, more positive

23.8 ? I'm gonna change the std rears for an AP set (260mm, 4pots), hope that this goes well with the master.

thats normal, needs more volume.
