I know Matt, It's called Sarcasm. Perhaps you're familiar with the concept?

for True Professional Jackassery I usually stick them with a fixed piston caliper and a hydraulic hand brake. Remember I come from the world of rally, where E braking is not only condoned, but often required.

 

Why not just run multipiston calipers, split the circuit into separate halves, and have the outside of the caliper activate the foot brake, and the inside of the caliper activate the handbrake ?

 

most of them have internal crossovers, so that's a bit of an issue.

but in addition to that, I can see putting full caliper pressure on one side of the disc, and none on the other. being a stress issue, but I'm a couple beers into the night, and not taking this too seriously. remember with a fixed piston caliper you might be deflecting the disc .3" or more if only using 1/2 of a fixed caliper. a sure recipe for fail.

 

i know that's how alot of drift cars do it, and it's surely easier than adding an additional caliper out back.

I personally want to replace my cable activated drums with wheel cylinder activated drums so i can run the hydro e brake as well

 

I don't know about the "dorifto" cars, but when we install a hydraulic handbrake in the rally cars, it just installs in-line with the rear calipers (Really it's just a master cylinder with a handle attached) when in the "rest" position it allows the fluid a clear flow through the piston, only when activated does it add pressure. to the line and closes all four rear pistons on the fixed calipers.

I don't want to say the drift way is wrong, but that seems like it can cause issues, and perhaps that was just one car you saw? I can't imagine a professional drift team setting up their calipers as dual channel. Maybe because I don't see the logic in doing it.

I like your Idea of swapping the cable for a wheel cylinder, and it should be a pretty easy modification. once again, overkill since a Hyd. handbrake can just activate your standard calipers without the extra work. and no need to run a second line and revisiour.

K-sport sells a nice hydraulic handbrake assembly for $250, (Street price is $187) thyey also sell a line kit with an fittings, but for $135 street price you can do better just buying the inverted flare couplings, some hard line and a bender.

Remember Matt, I'm a Brake and suspension geek.. I learned early that anyone can make a car go by throwing power at the problem, but it's the true geeks that can make a car stop and turn that hold my highest regard.
