As a class "A" mechanic i would have to agree xmr and say the rear flex lines could be shot. In my 1970 Plynouth Duster it has drum brakes all around and as I was driving to the track one day i had the lucky experience of brake lock up at a stop sign due to the breke fluid saturated the shoes. As it turns out, because the flex line was so old, it broke down from the inside and swollen up to the point of not letting fluid bak to master cyl. so every time you hit the brakes it keep that fluid in the wheel cyl and POP!! a blown cyl.

just my thought, you can take it or leave it but I hope it helps!!!

 

That sounds like you nailed it.

 

im gonna update all of u so we can close the thread..haha...turns out it was an axle seal and they were soaked in gera oil....the mechanics missed it...i took their word for it and never gave the seal a thought..10$ later its all sealed and i actually have brakes for the first time in a year and a half

 

The mechanics couldn't tell the difference between DOT3 and 90W?

 

correct...goodyear gemini place in buffalo...go figure
