LONG STORY SHORT:

can I take a shimano lever (designed for a disk brake) and put it on a magura front rim brake?

SHORT STORY LONG:

So I recently bought my first trials bike, I've been having lots of fun, but for the most part I've had no front brake because my step dad had a shot and ended up in a&e with half a brake lever inside his thigh :S I still have the callipers for the front rim brake but the lever is finished.

My local bike shop doesn't have any magura levers in stock at the moment so I was wondering if I could take a shimano lever and magura callipers as a set for a front rim brake?

short answer: no.

long one: disc and rim brakes have totally different hydraulic systems,disc is high pressure,low volume movement,rim brake the other way round.disc is semi-open,rimbrake closed circuit.

you'd end up with having virtually no lever travel and pad clearance,squishy pressure point.

i have a 2011 magura lever laying around you could use,not the best levers ever built but they work

thought it'd be the other way around? Disk brake levers use smaller diameter piston, so if you used it on magura slaves, you'd have lots of lever travel before it bit?

no,because its an open system you would pump the lever and refill the reservoir repatedly until your pads hit the rim,from there they would travel back just a mm when you release the lever.through the transmission the system and lever have the feedback on the lever blade would be what i described
