ok i bought a fd from steve ngan and he said he was removing the abs brakes and he gave me a wilwood thing for the brakes and i have no clue what to do with it...i am tight on money right now so i cant buy the whole abs system at this moment so does anyone know how to hook up the brakes with the wilwood?

 

You want to know how to hook up a "Wilwood thing"??? Folks, this is a solid example of how NOT to post for help.

 

What is the Wilwood thing?

 

My bet is on proportioning valve! Any other clues < this is a fun game>

 

Heh... if the Wilwood thing looks like this, you don't need it and I'll gladly take it off your hands... there should be at least two of them.

 

Sounds like he's using a Wilwood brake balance controller. It should have some brake line fittings and a ****.

It sounds like you may have a proportioning valve (aka balancing bar, bias adjustment). You do NOT want to play with a brake bias valve (balancing, proportioning valve) if you're not sure of what to do with it.

Ask the seller whether the current brake setup is set up for safe driving. If the front and rear bias is currently off, you need to take that valve to a professional and get it installed and adjusted properly. Midas or Meineke won't know what to do - a proportioning valve is a race item so you'll need to call around for a real, serious racing shop and not some ricer or rustang shop.

If the "thing" looks like the one here:


and the ABS has been removed, it would seem that the stock proportioning valve may be missing as well.

It seems very likely that you would not be able to determine if the stock valve is there or not, and I can't seem to find a picture of one.

IAC, the car should probably not be driven until some mechanically competent and 3rd gen knowledgeable person can check it out for you.

 

its a proportioning valve

 

sorry for not being as smart as you guys but what is a proportioning valve? just curious

 

Basically a valve which controls the fluid pressure balance to the front and rear brakes. Ever play Gran Turismo? LOL

 

Its a valve that restricts the fluid to the rear brakes, if its adjustable you can play with the diferential pressure front to rear.

 

I bought Steve's FD that he did a few years back (the one that was in Rotary Tuner and some other mags). He also removed the ABS in this as well. I never really thought FDs need ABS and very very rarely got my abs to kick off on my last FD (I think twice in two years - very bad conditions out).

Anyway, in my car he installed a Summit Racing proportioning value that lets you adjust the rear brake bias. My car was checked out by Dave at KD Rotary. Dave's feedback was that it was done well and he thought they did an excellent job in removing the ABS.

I assume that Steve did the same thing to the FD you purchased. Here is a shot of my engine. You can just make out the Summit value (the brake lines from the fluid reservoir run to the bias valve). The valve allows you to ajust the front to back brake bias to better balance the car.

o ok so it means like you can have more pressure in the front than the rear so they grab more than the rear.. i get it.. and no i dont like Gran Turismo too much.. more of a forza kinda guy,.. but also i never rear anything about a proportioning valve in gt or forza its just brake pressure, more towards the rear or front

 

I was always under the impression that there is already a prop valve in the master cylinder and another external one for the rears isn't necessary. Can anyone confirm this for sure?

 

I can confirm that it's wrong. The stock PV is attached to the ABS unit, even though they're not mechanically related. That's why some people remove the PV when deleting ABS.

ok ive been reading up on the proportional valve install and this is how i see how it goes...the two front lines go into a tee which plumb into the fluid resevior...from the fluid reservior a line goes into the proportional valve then out of the proportional valve to the rear lines..am i correct? the only question i have is which hole on the resevior is for the front brakes the one closest or the one farthest away from the plastic that holds the fluid?

 

The one closest to the resevior is for the fronts. the one furthest is for the rears. you would put the prop valve inline with the rears. here is my setup, with no prop valve (yet)

 

ok thats what i thought but i got confused by ferra picture his looks like its backworks
