Your hypocricy is showing. Backpedaling doesn't change what you wrote.

 

 

Out of respect to the OP I will not respond to any more of your verbal bashing here. You seem to have an attitude problem towards me. If you like we can discuss it like civilized adults in a PM.

 

Glad i could help you. Dont p.m. me please its a nice offer thanks though.

I don't see any room for argument here...no need to. Heres what I did. http://i177.photobucket.com/albums/w239/johnboy9788/IMAG0803.jpg

Still trying to decide on how I want the handle.

Have not been on in a while. Little update. Handbrake worked fantastic. I did originally install the lines backwards. From what you would believe to be the correct way is incorrect. Regardless. All plumed and bled. No leaks. Have fantastic pedal feel. Locks up the rears with little effort. 15mph to 50mph have been my test thus far. Normally around 50-75 degrees F. These are my tires

Overall I am very happy with this mod. Lost little pedal when handbrake is engaged and foot braking. All in all, totally worth it.

The worst part is that I've yet to figure out how to attach the sensor for the brake lights in a clean manner

 

Have you looked into brake light pressure switches? http://www.summitracing.com/parts/PRF-80171/

 

It comes down to mechanical advantage, friction and application of force. Bearing those in mind can the hydrolic system apply more force to the rear pads. If so how much more? A significant amount or just a little more?

Don't forget that you can adjust you mechanical advantage by selecting certain bore sizes on the master cylinder. You are trading force for distance: http://science.howstuffworks.com/transport/engines-equipment/hydraulic1.htm

Working on a similar inline hand brake setup on my Toyota....

 

I found that 10mm banjo to M10x1 inverted flare adapters off of junkyard Mazda Miata master cylinders work great on the outlet of the Wilwood master cylinder(10mm and 3/8" banjos are interchangeable).

Only other part needed is a 3/8" - 24 banjo bolt w/washers. I used a Russel 640650 banjo bolt. It was slightly too long, so I trimmed it down a bit.

Also running an adjustable proportioning valve in line before the hand brake master cylinder. Joining the two with a -3 an to 7/16" banjo braided line.

All built with 16ga steel from Lowes, a 1986 Mazda Protege shift lever welded to an inverted Toyota Corolla clutch pedal, and topped off with an Isuzu Trooper 4WD transfer case shift knob :P

(For newbs)

 

This is great for the track not really that great for a DD since parking brakes are just that, for parking.

Even if you use the click stop lever, the fail safe is a cable doesn't have the posibility of leaking fluid while engaged.

 

These modifications are also only applicable if the Anti-lock system is disabled or removed.

 

(for everyone else)

 

On an off topic note I would like to know if anyone has modified the anti-lock modulator as an air pump,

for other applications like air lockers or air suspensions????

SFBMX, that's the trickest hydro ebrake I've seen in a non-megabuck car. Also, great info on the fittings and small stuff that make you take five trips to the hardware store or Pep Boys trying to figure out.

 

Anybody running dual rear calpiers with a hydro setup? That's the way I want to go.
