Brake problem driving me crazy!, UPDATE PG2!!!!!!!!!!!! Options

[Justin]

Ok, I recently decided to replace my master cylinder in my car because A. There was a lack of pedal pressure and B. I could not get any fluid to bleed out of the front right or left rear brakes. After I replaced the master cylinder with a reman I am still having the same problem. I made sure to reinstall all gaskets and O-rings, and to properly bleed the master cylinder before install. I have gone as far as removing the proportioning valve to make sure it still worked properly and it did and had no clogs. So as it sits right now I have good pressure to the front left and right rear brakes but no pressure to the right front or left rear brakes.

The master cylinder is providing pressure to the proportioning valve as proved by removing the line at the prop valve. I also sprayed all of the lines with windex and tried to find a leak but have not been able to find one. also checked the lines for any kinks but found nothing. Any ideas?

AC Delco is a Toyota supplier now....

I don't know whether to be scared or glad.

LOL its better than autozone (Fenco) atleast. My brake pedal still goes to far down. I've tried bleeding the brakes (properly) but that didnt really do anything. It seems as if when you first step on the pedal the front brakes bite but the rear doesn't engage until about halfway down. I think it could be that the rear shoes are worn so far that the brake cylinder has to travel so far. So I am going to have a look at that tomorrow. Is it also a possibility that the front calipers may not be good? I did get them from a junkyard when my stock ones were sticking. I think they are from a GT and I dont know if that makes a difference. They fit perfect and don't leak or stick. Any suggestions?

adjust out your rear shoes. Even a little bit of clearence can make a big difference.
