Has anyone fitted there handbrake to the front wheels? I have a hydraulic handbrake that I want to plumb into my front breaks so I can lock them up without locking the rears like a line lock I have twin cylinders on an obp pedal box so I am unsure how a conventional line lock would work

Don't know if you are aware but a hydraulic hand brake will not pas an MOT test let alone an IVA test. So for a road car it's a no no

sorry didnt think to put that its foor a track car

Why would you want a handbrake on a track car?
I have never had one on any of mine.

i want to be able to lock the fronts but be able to spin the rears when im at santapod

plumb it into which ever cylinder is for the fronts - assuming the cylinders are 1 for front and 1 for back.
