Hydraulic handbrake
Discussion
Yep, it's solely an hydraulic system that causes issues.
Drifters tend to keep the original and have a hydro fitted for skids.
(remember, call it a "hydro" and "skids")
The newer push button stuff on cars that don't have a lever are electro-mechanical I believe, they use a solenoid or motor to clamp the rear discs.

That's kind of what I mean, like could you fit a hydraulic override system onto a electrical handbrake so you have mechanical for parking and the hydro for skidsDrifters tend to keep the original and have a hydro fitted for skids.

I think how it works is the hydro cuts into the rear brake lines, so (depending on the car type) your original handbrake will work on shoes inside the brake disc hub, and the hydro will pump up the normal hydraulic lines for the rear calipers, so it's like stamping on the brake pedal, but it only works on the rear wheels.

My car just has drum brakes and will be converted to discs so idk how that will work. They disc kit comes with a cable for the handbrake but I'd like a hydraulic one for skids and stuffMaxRothery said:

So just fit a hydraulic handbrake. Why are you trying to complicate it ? You dont need two calipers
As long as the caliper has a hydraulic line, the hydraulic handbrake will work in conjunction with the normal braking system.
I presume this is for the Triumph Spitfire you have started other threads about?
I fitted a hydraulic handbrake to my Triumph Vitesse, by putting a master cylinder in the line to the rear brakes, modifying the lever to actuate it and retaining the cable (as above).
The MoT man said he couldn't tell if the handbrake was actuated by hydraulics or cable, so passed it, annually!
If you do this as I did, reinforce the hump of the transmission tunnel where the M/cylinders sits behind the lever - it needs it.

Having owned a Spitfire many decades ago and still having nightmares from the liftoff oversteer and the huge camber change WHY O WHY would you want to lock the rears up???
As I remember if pushing on hard round the lanes if mates in Fords lifted off I had to press on regardless or suffer uncontrolled oversteer as the back came up and the wheels tried to tuck under.

Paul,
You are not supposed to lift off in corners!
The problem is inherent to the swing axle design, not just the Triumph Spitfire.
See VWs, early Porsches and Mercedes, Chevvie Corvair, etc.etc.
Triumph overcame the problem with their swing spring design, which AFAIK was unique to the marque.
Have to say, though, that I fitted the hydraulic version because I couldn't get Triumph's cable version to work very well!

its a 1500TC dolomite so it doesn't have swing arm suspension, just a solid axleI fitted a hydraulic handbrake to my Triumph Vitesse, by putting a master cylinder in the line to the rear brakes, modifying the lever to actuate it and retaining the cable (as above).
