I want to hook up my linelock.All my lines are hooked up the factory way now to the factory proportioning valve.The car is a 68 stang with factory discs in the front and drums in the rear.
Heres what I was thinking of doing.Tell me if it will work or not.
I was going to come out of the port for the front brakes on the master into my linelock then out of the line lock into a "T" fitting then branch out to the calipers.For the rears I am coming out of the master into an aftermarket proportioning valve then out of the valve to the rear brakes.
Will this work?Am I correct in thinking that the front brakes dont need a prop. valve, just a junction or "T" ? I am using all 3/16" hard line.
Any tips? Whats the best way to adjust the valve? Do I need a gauge to test line pressure?
I am eliminating the factory prop. valve all together.

Sounds fine Bob.
A pressure gauge is the only way you can accuratly adjust the F/R biased. Otherwise it will have to be trial and error.
You will need at least a quart or brake fluid for bleeding and stay away from the silicone "racing" stuff. It will give you a very mushy pedal.

Thanks Alex, you dont happen to know the pressures I should be looking for do you.I know they will be different front to rear.If not I'm sure I can call Master power brakes tech line.One more thing is it better to use the valve with the adjustable knob or the type with the click lever?

Well, you'll need at least 1000 PSI for the line lock to be effective and the rear's will be dependant on what type of brakes you have but they will be at least 40% less than the fronts.

the brake bias trial and error can be done by hard stops in a wet parking lot. Minimize the risk of "error" by doing it when cars aren't parked there.

I know I shouldnt even second guess you guys,Especially Alex but I gotta ask.A guy on another board is telling me that the setup I want to use wont be safe.He is saying that I should not eliminate the stock valve because it has some sort of safety feature built into it in case I develop a leak.I say if all my lines are double flared properly and I have no leaks I shouldnt have a problem.He has told me to use the stock valve and block off one of the front ports and to use the other to go into the L.L.then to a T and plumb to the fronts.
I think the way I described to you first Alex seems simpler and makes sense.
Again Not to second guess any one.I just want to be able to do nice smokies and be able to safely stop this Roach!
Thanks
BOB

Let's get a couple things straight here Bob so you don't confuse yourself any further.

The "factory prop. valve" that you call it should really be called a "distribution block". A distribution block is just like your "T-fitting". It distributes brake fluid to your left and right front brakes ('65-'66 had single outlet bowl MC which distributes to ALL brakes).

In theory you can put your line lock between your master cylinder and your distribution block and use a flare plug to plus any open ports in the distribution block (if any). Buy an adjustable proportioning valve that goes in between the rear master cylinder port and the rear main brake line.

Hope this helps.

Erik

What the other guy is trying to say.......

The stock valve does have a sliding valve inside. If one side should fail, it will close off that side and help prevent total brake pedal travel.

But, with that said, There are a number of cars on the road and the race track that do not have this valve installed anymore nor do they have dual mater cylinders like we do today and they stop just fine. The vavle was probably madated by the Fed's or Ralph Nader.

Bob, you don't owe me an appology. I'm pretty thick skinned.
Maybe the rest of the M&M gang here might feel a bit slighted though.
Our tight little fraternity always goes to the highest levels towards trying to help members with aid or advice. They (as maybe I a little) might feel a bit underminded when several offer sound advice and they are second guessed by "another board". Might make some feel like "why ask us if you are going to go elsewhere anyway?"

Just an observation.
