Running brake lines from Master C, & Proportioning Valve

Mr_Evil · May 20th, 2007, 06:59 PM

When you run your brake lines. The stock Master Cylinder has three outs... Shouldnt it go like this... two of the lines through proportioning valve then out the p-valve to the front brakes... then one line out the Master Cylinder to the brake line to the rears...?

The proportioning valve regulates the rear brake pressure. The line on the bottom of the master cyilinder should go to the left front brake. The other two go to the proportioning valve. From there one goes to the rear and the other to the right front brake. Are you trying to install a line lock or something?

Yeah, I later figured this out (that the stock valve doesnt work like the aftermarket ones). I should have updated the post...

No, I put on some new front brakes and steel lines. I thought that possibly the lines were wrong, thats why I had some pulling to one side at times. I now know this is a flaw in the stock system.

Plus,... I bought the car with the 5 lug/4 disc conversion done. So I didnt know just a whole lot about it at the time. It still had on the stock master cylinder, and that is too small. So now I am going to replace it and put on a new proportioning valve. No need for the line lock doing it this away.
