Dont feal bad. I generaly go and replace all that stuff anyways. Thats why my cars never break. They have all new parts on them.

 

This is true.

 

There's a hard plastic one-way check valve in the line from the intake manifold to the brake master cylinder. If it's not there you can blow out the seals in the brake master cylider, then it's kaput, needs replacement.

Here's something to check- are those original brake lines? I've heard of old rubber lines rotting and actually having flaps rot away inside so that when you press the brakes it locks pressure in the line which slowly seeps away. Something to check before you throw more parts at it.

Also, very sorry about the edit. I'm tired and not familiar with the new mod buttons, and I thought I hit "quote" . I put the post back to the way it was, minus my comments .

 

Ill be sure to look in to the lines. If the master doesnt fix it or the proportioning valve I guess Ill be moving on to SS lines next. Oh well at least I wont have to worry about the brakes for a while!

 

Im replacing the master cylinder tonight. Ill let you know how it went in a few hours...

 

Make sure you bleed the cylinder also.

 

How do I bleed the clyinder? I already have it on there and started to bleed the brakes... I went through about 7 bleeding sessions and every time the back left and front right kept having air come out, yet the back left and front right had nothing come out not even fluid...

Did I already fuck something up from not bleeding the cylinder to start? or is there still hope...
