Hydraulic Emergency Brake Install (in line) DIY
« on: 12:12:46 AM / 20-Oct-10 »
new OEM (yea oem, ones that fit, and last) s12 brake cables are hard to get, sometimes expensive if so, and never last if your into drifting, and need lots of adjustment, especially if you drive on the e brake alot by accident


PROS OF HYDRO BRAKE

no stretching cables,
solution to those who cant use a e brake
longer life
consistent lock

CONS OF HYDRO E BRAKE

they cost money
you cant press the brake pedal while pulling the lever
you cant modulate lock
 


heres a quick writeup

tools needed.

FLARE WRENCH 10 MILL


use that wrench, and that type of wrench ONLY for removing those old brake lines. get a pair of good vice grips if you strip them out



i purchased a CNC series 412 staging brake. you have to call to order, shipped to me. [va] it was around 180 American dollars
http://www.cncbrakes.com/hsb.asp?grp=hsb&subgrp=all&series=412&subseries=


why staging brake?
because i want a IN LINE setup, which means were using my stock rear calipers to lock my 15 inch steelies up mid drift

if your installing separate calipers (probally better, but cost more/more fabrication) youd need a hand brake, which cnc sells also. which just has 1 exiting port from the cylinder



heres the brake


its got 2 ports, comes with SAE fittings that have PIPE thread on them, do NOT try to hook up a flared brake line to the cylinder, itself, use the pipe thread adapters it comes with.

i dunno if you can buy metric ones, mine was SAE, 3/8th's by -24           3/16th brake line (which is our stock brake line size)

get 2 4 foot sections or so of brake line, and flare 2 SAE fittings onto the fitting on the cylinder, and make sure the line you buy has metric, (probally 1.0 mm) so the opposite end will go into the master

you can rent a double flare tool at your local autozone for free. just pay collateral and you get your money back afterwards.
if your a pussy and you do not want to learn how to flare brake lines, try to source a adapter.

results should look like this once its all done.



you will need a union fitting, i believe 1.0mm 3/16th line


and 2 4 foot sections of 3/16ths line, longer if you want, w/e you can always cut them to your desired length. INVERTED FLARE NOT BUBBLE FLARE


what your going to do, is disconnect the 3rd, or last brake line that goes into the master, add the union fitting, then place a line from the fitting, INTO the back of the hydro brake,

then run the FRONT (should be labeled) right back up into the master cylinder

picture for reference




heres how it looks in real life. i removed my dash because i have it held in by 2 zip ties. you can try to go around it



i bolted mine down on the trans tunnel. you can do w/e you want


bleed your brakes good

put everything back, and BAM go rip that shit down the freeway it 75 mph. its awesome

sick! so the rear brakes still function normally?

we've been trying to come up with a cheap solution for the socaltwelve, could we just use something like a clutch master cyl? or something else? $180 is kinda a lot

clutch master will work, if you can find one that has a brake like fitting for the inlet.

I stickied this because i love it...and i sticky the things i love.

The only thing i dont like is that you cant use the brakes while engaging the hydro brake...but other than that, its pure win.

no wonder ive been waking up in washington with sticky stuff all over me.

hmm, dont most? could i put a clutch line fitting on a master? wait, how would fluid go in, i imagine we'd need a tee of some kind? and perhaps a check ball?

For the outlet yea, but the way it needs to work, is the brake line IN to the small master cylinder is the fluid feed (from the brake master) then the fluid out from the small master goes to the rear brakes.
So instead of a fluid reservoir, you need a brake line fitting (and has to be able to hold brake line pressure, so like 1000PSI)

I did this . . .



Not allowed verticle hand brakes as of next rally season  :grumpy:

Now on the MOT the cables will still move the caliper arms (just - to pass MOT), but are slacked off so under bugger all strain. Super cheapo hydraulic hand brake.  :angel:
