Bad Brake Booster?

[bigcurt]

When I drive my DA after about 15 mins the brakes lock up and I have to sit and wait until they unlock before i can move again..Is this a sign of a bad Brake booster?

Sounds like your brake lines need to be flushed.
Have you ever had your brake system bled?

Ive only bled the system at each wheel and thats it as far as bleeding goes.

I put new calipers on (used) and new steel braided brake hoses

I had the same problem, replaced all the lines and calipers and pads but it still happened. turned out the break master and slave were bad. After that I haven't had them lock up once.
