How-To: Hydraulic Ebrake
« on: 10:49:44 PM / 18-Feb-09 »
I got tired of searching through endless websites on the topic and after all that shit i came up with the following conclusions and wrote this article:

THE QUICK AND DIRTY DIY HYDRAULIC EBRAKE THREAD:

-Mount your hydraulic brake

-Drill 2 holes for your inlet and outlet lines

-Locate your rear brake line

-Bring your brake line to the inlet on the ebrake

-From your outlet, goto your main brake master cylinder

-Do not "T" inline with your brakes

-Just install the hydro brake inline between your master cylinder and rear brakes

-Make sure you don't have the inlet and outlet lines on the hydro brake backwards (check with the manufacturer) and be careful that some hydro brakes also have a reservoir outlet for bleeding.

-Do not use long braided hoses or add extra length to your lines, try to keep it as
 close to oem length as possible or your pedals might feel more "mushy"

-Do not pull on the ebrake handle or "play with it" until there is fluid in it or you will damage the seals

-Bleed from the rear brakes only


A couple quick and effective ways of bleeding the brake/hydro lines:

  1) Pump the brake pedal several times then hold it down... once you do that immediately pull the e-brake then open the bleeder on one of the rear brakes

  2) When I bleed them, I hook up a line to the rear brakes, that line goes into a container full of brake fluid. I open the bleeder, I then smoothly and slowly pump the brake pedal and the e-brake, however MAKE SURE the brake MC reservoir stays full. I alternate how I do the brake and e-brake and try and do them together some times.

  3) I do bleed the handbrake itself after I bleed the brakes as normal, I bleed a fair bit of fluid through the system in the normal way and then I bleed the handbrake itself just as you would the normal brakes. Pull up on the lever and crack the nipple, close it before releasing the lever and keep repeating this a lot. Keep doing this until no air comes out and then go back to a normal bleed to finish.

  4) pump pump pump, open, pedal to the floor, staging brake to the bottom (aka pulled all the way), hold stageing brake down, pump pedal back up, keep tension on the staging brake handle till at the top. Couple times of that and we were done.


Also Here's the link for CNC's suggestion on How-To bleed the brake lines:

Products that are out there:

Its a matter of opinon or price your after but you should do some research on what suits your needs. The CNC one is the cheapest route of the bunch but seems to have the most problems. The problem with it is when you pull the hydraulic ebrake and touch the brake pedal the same time (by accident in mid drift for example) the handle might not release and you might have to pump the pedal several times to get it free. CNC uses a check valve when pulled. When you hit the (2) brakes it gets stuck shut because of pressure from the wrong side. Upgrade you master cylinder on the hydraulic brake to a Wilwood one (who have already solved this problem), Or just buy a brake with one already installed. I haven't seen a single complaint about the Wilwood yet. Some setups (like Ksport, D2) come with an adjustable lever so you can mount the lever either horizontal or verticle. It also has a lock to keep it *up* like the stock handbrake. Cheap way to go is buy a conversion kit and buy the lever seperate - some guys like using the aluminum handle that come with floor floor jacks, they're cheap and they already have a grip on them!

If your thinking about installing a hyraulic ebrake, you should also think about leaving the stock ebrake in place in case of emergency you have a brake failure in one of your lines you still have that last resort available to you (which is what it was intended for), it might not be worth shaving off that 3-5lbs off your car in the end. Also check your region to make sure its even legal to remove your existing ebrake.

i got tired of reading a hundred different opinions on 20 somethin websites with no real answer. After all that reading at least now if you want a answer - there it is. If anyone wants to add to it, i'll be happy to edit and add it to the post. What it needs is someone with some good photoshop skillz for a diagram or some sort of picture...

All in all u can probably do it all in one evening, the longest part is taking ur time cutting ur lines, bending them and flaring the ends, followed by bleeding ur lines, makin sure u don't have any air trapped. The length of time depends on ur experience  with bending and flaring ur brake lines and how good u want it to look...

Optionally you can use a clutch master cylinder and essentially do the exact same thing if you are handy. The larger the cylinder the less travel needed to lock it up.


Clutch pedal + hack saw + grinder + spray paint + duct tape = handle

excellent source of info for those wanting to do hydro ebrakes

oh, and i moved this thread to handling tech and sticked it, as suggested by Sterling. nice job


"like people, every car possesses a unique character, with its own DNA, talents, and idiosyncrasies. push it too hard and it'll turn on you, as a person would. if its worth anything, it gets more interesting the more you get to know it"

luck is earned through hard work and determination, not to mention the willingness to take risks and to see bad luck and setbacks as opportunities for growth and a new direction.
