Adjustable brake proportioning valve Q's
I have 11" Fastbrakes Front Kit w/Drum Brakes in the rear on my EG 4-dr. Because of that setup, my fronts are very easy to lock up, especially in the wet. In the other words, I have a heavy front biased brakes. Since I CAN'T afford the rear disk brake swap, it seems logical to install the adjustable brake proportioning valve & get the brake force distributed more to my liking. Here's some links:

Has anyone TRIED it? How difficult is it to adapt the valve to Honda's brake lines? How's the threads?
I'd greatly appreciate any knowledgable replies!!!
Thanx in advance,
Yuri K

Re: Adjustable brake proportioning valve Q's (Civic1992DX)
Based upon what you stated I suspect the adjustable valves won't really help you. The proportioning is probably not the problem, rather a lack of traction under the full load conditions. Unless the tires are up to the task of maintaining the friction levels necessary to grip the road under those conditions, the tires will always slide.

To: fastbrakes (Brian H)
Brian, your front kit is awesome! Just because of the larger calipers in the front + larger rotor diameter even with the same master cylinder & proportioning valve Front brakes are much stronger. This just emphisizes how weak the drum brakes are in the rear.
Tires: 205/50R15 Pirelli 7000 mounted on 11lbs rims. They have around 5k miles. Spring rates: 380F, 250R, therefore the car doesn't have any noticable dive under the braking, especially with Bilstein shocks.
So, I don't think it's the tires that create the problem. Because the front brakes have so much clamping force then the rears, I need to limit the flow of the brake fluid to the fronts with adjustable proportioning valve. The flow to the rear brakes would be untouched. The PROBLEM IS (pintointed by Mista Bone!) that the front flow is split in two, meaning that I'd need 2 proportioning valves. Now, how possible is it to adjust the flow to the LEFT & RIGHT brakes? Some tandem proportioning valve? ANy ideas? Is this the first time someone thought of this?
Thanx, fellows!

Re: To: fastbrakes (Civic1992DX)
I'm with you on this... I have the same kit on my EJ Civic. I've been interested in getting the prop valve too, but haven't a clue who would know how to put one(or two?) in! Brakes are one thing I just won't touch anymore (save for changing pads).
Anyone have any ideas? Help us!

Re: To: fastbrakes (PyroVTEC)
Ok guys here ya go :-
Honda manufactures setup up their brake system ( the diagonal system ) so that if one line fails there will still be front and rear pressure .
what i did was to route the front line together tru the stock proportional valve (top)and block off the other lines ( tap and plug ) .
Then run the rear line that comes from the master cylinder ( i bought new line and bent it to my specs ) tru the aftermarket proportional valve and from there the out line "Ts" off to each rear wheel .
the car should be driven fairly slowly to feel in the brakes then adjust the bias (rear wheel bias) to your needs . mine is set a little more to the rear so that i can approach a corner and brake and the back steps out of line a little .
I got help doin this from an engineer from one of the Rally teams here , so he knows his stuff .
