Kustomizer - Excellent explanation! That is just how a line lock works. Mine works just like you described!

darn it, no one anwerd my question
"i dont know if this would work or not but would it work the same if you had one of those proportioning valves on your brakes and just have all the fluid go to the front??? or would that cause problems"

Yes, it would work with a proportioning valve, since as far as your brakes are concerned, there's nothing different with the line-lock off. Additionally, proportioning valves are for front-to-rear setup (and usually you've got a master cylinder with both ports).

With the line-lock off, your brakes work like normal. When you press your foot on the brake pedal, high-pressure fluid (at different pressures because of your proportioning valve) travels to front and rear brakes. When you engage the line-lock (under pedal pressure), the fluid in the fronts isn't allowed to return to the master cylinder, but the rear is. The rear is usually where the proportioning goes anyway... but even if it wasn't, proportioning valves are a 1-way type of valve, restricting flow TO the brakes, not returning to the MC.

As far as your master cylinder, proportioning valve, and rear brakes, they all follow your pedal. Only the last foot of brake-line to your front brakes is affected by this solenoid.

I have a device on my truck that uses only line pressure to hold,no solinoid.You step on the brake and push in the button then release the brake and the front brakes remain locked,rev to optimum RPM and release clutch,with rear tires roasting ,tap brake pedal and it releases. Cool accessory. Says Jomar on it.Got it out of J.C.Whitney 15 years ago.

Kustomizer: You are exactly correct in your explanation of what a line lock does and how it performs. And, your explanation is simple enough so that others can understand it. My line lock works exactly as you've described. I used to foot pedal coming off the line. Now I use my trans lock. Great job on your explanation!

Oh no she's back.

Ghetto, Thanks for the warm welcome. It's nice to be back, but I never left.

I had a race car to build and finish. Then I had to shake MAX down and get some test/tune runs on him. I still have some more shake down runs to do yet. So, in other words, I had other things to do.

And, I wanted to check out this line lock thread as I've got a new LL on MAX -- my '71 Duster that you are very familiar with. Helpful tips and information are always nice.

And I've found that Kustomizer always lends a helpful hand and always provides excellent information. So, if I see a post by Kustomizer, I certainly take a look at it.

You make me blush. I'm not right all the time, I've just probably made more mistakes than everyone else

Cya guys-

Kustomizer

Naaaa, we've all made mistakes and we've, hopefully, learned lessons from our mistakes. But it's true, you have a great deal of knowledge and a wealth of information and I appreciate your sharing it! And, no need to blush. You're a great guy that just happens to possess a brillant mind!

Question??? Does a proportioning valve lower the pressure to the rear brakes or does it just change the rate the pressure is built up to the rear brakes. I have herd both answers Ed ke6bnl

I've heard both, too, and I think it's because both types exist. I've seen proportioning-valves that have spring-regulators in them, and I've seen "valves" that were nothing more than fixed-orfices. Personally, I'd opt for a true spring-type regulator.

The question you ask is the same question everyone asks about paint guns... are you better-off with a regulator right on the gun or with an adjustable flow valve on it? I always opt for a regulator, because you always get the same pressure (as opposed to a flow-valve that is always a percentage-drop).

Cya!

im still confused about the ''1970 Chevelle FWD?''

Ha! I'll bet it had good traction with the weight over the wheels! Look pretty silly doin' burnouts though! Nice fat tires up front, doing backwards donuts, now THAT's the kind of Chevelle I wanna see!

I installed a 1966 front sub frame and transaxle form a Toronado.

I adapted a small block chevy motor to it.

Added a 6-71 blower.

THe car was a hand full to drive under hard throttle. Lots of torque steer and the car tended to follow the road as the front tires smoked.

The car appeared in various magizines of the day. In a video on Super Chevy, in a TV show pilot ( it flopped) as back ground filler in a parking lot
