Hydro handbrake install...

Post by Talkiet » Mon Oct 22, 2018 11:16 am

So so so many conflicting bits of info on the Internet... I have a hydro handbrake that I'd like to put in to my car. I will leave the existing cable parking brake there as well. The brake system is dual circuit, discs front and back.

Current:

And here's my initial take at how to stick the brake in...

And here's the Aliexpress special brake (I'm prepared to change the cylinder if necessary)

Am I ok with my proposed install? Anything to watch for? Completely wrong?

Cheers - N

My only thought is - is there flow to the rear brakes when you press the foot brake! Or will your hydro brake just treat everything upstream of it as a reservoir?

Can you make provisions for seperate Calipers and have an independant system altogether ? This is the only way I have found for a good set up other wise you can get mutable issues , spongey pedal , hydro leaver that moves when pedal is depressed , caliper that doesn’t release from the disc well , the list can go on and on.
I do note I havent set one up on a car with twin reservoirs but can’t se that changing any of the above

I believe that's the best way to do it and if a simple approach doesn't work well enough then yes I'd consider it, but it's a lot more work and expense. I will make sure there's good spring pressure to ensure the hand brake retracts fully.

Installed inline last night and tested today. Works brilliantly. Prepared to replace the Chinese master cylinder if it gives any issues. Bleeding was a pain, even with a vacuum bleeder. I resorted to running a line from the bleed nipples at the rear to the master cyl reservoir at the front and just pumping through (foot and handbrake) in a circuit until it ran perfectly clear with no bubbles. That always works best for me.

Cheers N
