Hydraulic e-brake install

G37Sam

Has anyone attempted this on their Z's?

Do the rear brake lines join at some point?

My installer is saying they exit the ABS unit and each makes its way to the caliper on its own. Guess the only way to do this would be to tap into them with a T-connector.

Any help on this would be appreciated.

Cheers,
Sam

I'm not 100% certain on this, but I think the front left and right rear are one circuit and front right and real left are another. Thats the way most cars are now in case of a line rupture.

This was my understanding as well for traditional cars.

That said, we do have EBD with a big EBD block with 4 lines come out of it.

I'm thinking our cars probably have a single line per wheel, can't fathom how else EBD would work.

Yeah that's what I noticed under the hood.



Where do you reckon the best place to tap into that would be? Could I utilize the OEM e-brake lines?

The OEM e-brake, like basically every (normal) car ever, isn't hydraulic. It uses cables.

You'd have to tap into the brake line, probably at the rear wheel, at the hard line's end point.

Not worth the effort in the least.

Edit: Unless you're building a drift car. In which case, go for it.

The problem is, I deleted my OEM foot e-brake to make room for my clutch pedal. That left me with two options:

a) buy an MT center console and have it shipped from the US, with the oem handbrake assembly

b) pick up a hydraulic e-brake locally that I can use to both park my car and drift it

b sounded like more fun and less downtime

All the brakes I've worked on (none very new) had the front and rear on separate circuits.
If you just have rear brakes, you don't have much traction, but one front brake can cause the car to pull in the direction of the functioning brake - often pretty hard.

A lot of modern cars control each wheel separately as part of the traction/stability function.


In any case, the OPs question sounds like one of those "if you have to ask, you shouldn't be messing with it" things.

Trust me, I wouldn't be messing it if I had another choice. And I'm getting a professional shop to do it, won't be attempting this myself.
