Simple. For the rear brakes. Start at the Front. Bleed at the bolt holding your hose on the master,,then bleed at the bolt holding the hose in the caliper.. Then bleed at the bleeder. Fr to back,,she'll firm right up. I haven't done any res swapping,,but I think alot use the 400EX fronts.

According to a member here named 3 legged dog, he says a Suzuki z 400 quad rear master cylinder is a direct bolt on for the 85-86 250R.
I have not tried it myself though, but I believe his info to be good.
