You can get the new from Ford, i presume you do know that?

 

how much are they? how good are they?

 

I think they are like ching ching £100 kind of money, and i have no idea, same quality as the rest.

To be fair a failed master cylinder is a rare occurence on a MK4

 

true, I meant how is it gona get on with my cossie stoppers? will i notice a big difference in braking/stopping distances or is it something that will be "feel"?

sorry to jack the other guys thread, but I'm doing my brakes too...

 

In theory it should reduce pedal travel, make the brakes more responsive and also a lot more powerful in stopping, a bigger master cylinder means more force

Edited to clarify

 

bigger pistons make for more pedal travell thats a fact.
but they will work better so you wont have to press them as hard as the standard ones so they will be just a bit spongey.

 

I meant bigger pistons inside the master cylinder........so that reduces travel

 

rightio then. and the 25mm one has only 2 outlets instead of 4?

 

I believe so, i did think there was such a thing as an RS without ABS but i was wrong so a 2 outlet item is all you will find i think

 

split the pipes like this;
