I'm at odds with my bike tech. Usually he's right, but this time I think he's wrong. Got a WR450 with a Revloc clutch and want a hydraulic left-hand brake with a T-Joint/Check Ball steel braided in to my rear caliper. I say a good juice clutch like a Magura "Jack" will do the job of actuating the rear brake calipers. He says it has to be a beefier juice clutch off a street bike (yuk !). Who do you think is right ?
