Bigman Posted January 22, 2007 Report Share Posted January 22, 2007 Right, this is abot of research for one of my college projects, we are planning on using a disc brake on the rear of a 4 wheeled human powered offroad vehicle, becuase of this we have certian calculations which we need to produce.For these i need the piston sizes (master and slave diameters) which are used on the most common discs, ie magura, hope etcIf you could list the maufacturer and then the diameters it would be greatly appriciated.ThanksAdam Quote Link to comment Share on other sites More sharing options...
Waddy Posted January 22, 2007 Report Share Posted January 22, 2007 ha ha sounds cool adam , i think a hope mono trial has 25/20mm slave piston and a 10mm master cylinder Quote Link to comment Share on other sites More sharing options...

Greetings Posted January 23, 2007 Report Share Posted January 23, 2007 Very interesting topic if you get some replies. This would allow for a brake with loads of mechanical advantage to be put together without having to spend hundreds of pounds on Hope's. What was about 4 years ago named a Giant MPH3 is essentially a C2 with a Pro lever? If so, one could get a Hope Mini lever and increase the mechanical advantage by 60%, resulting in at least 40% increase in power. Anybody tried that? The MP3 are stupidly cheap.
