Soft brake pedal

[ricola]

The golf is a bolt on, you may have to use the golf reservoir too as the reservoir ports are a different size and also shorten the pushrod a bit from memory. I'd be very wary about going as big as a 24mm, pedal forces will go up a LOT, remember it's fluid pressure that gives you braking and the area increase going from 19 to 24 is 60% so you will need that much more pedal force for the same braking. It is also harder to modulate the brakes when you have much reduced travel. I'd go for the smallest you can get away with..
