I have bigger calipers on my 250ninja than i do on my 180sx rear. I got a pair of R32 calipers and it appears they have a hydrolic line for the handbrake. Can anyone tell me R32's have hydrolic hand break, if the line joins to some sort of master cylinder near the rear, does it go all the way to the engine bay or recommend a good way to go about the swap?

no, the caliper is for rear brakes only, no hydraulic hand brake, the handbrake is cable and is a drum brake that acts on the inner hub of the rotor

Thnx, i'll go to a wreckers and check out what piece i am missing
