Hey Guys this the first time I have posted here but I do read a lot of threads.
I could really use some advice on My 98 gt non-abs brake system.
I recently replaced all the Calipers and bled all the brakes in proper order and also bled the Master Cylinder. After 9 rounds of bleeding and 64 ounces of Brake fluid I still couldn't get any pressure, never ran the MC low.
I had it towed to a garage so they could inspect everything and give it a another bleeding just in case I missed something.
So the shop has had My car for 9 days and called Me yesterday to tow it out of there.
They replaced the Master Cylinder with 2 new ones thinking the 1st replacement was bad. They bled the brakes until no bubbles came out of the lines several times.
Now I'm not sure what to do.
The Mechanic mentioned it might be the Proportioning Valve or the Booster. When I changed out Calipers for an upgrade all these things worked fine.
Any help is appreciated.
I have read most of the Brake threads which address things I have already done.
Thank You in advance! Joe

I was hoping for a simple fix ,a friend had them switched left to right and that put the bleeders on the bottom and they wouldn't bleed .sorry that's all I have.

No worries thanks for the reply anyway!
I am leaning towards a small leak in one of the brake hoses.

Small leak, you should still have pedal.

Does pedal firm up hard as a rock with engine off?

+1 a small leak you should still get pedal. And a steady stream of brake fluid dripping out from under the car somewhere. Fluid level has not dropped at all?
