Thanks you for your help. I'm getting another one tomorrow to replace it all and see how I go. Thanks

I know buddy, I just have no glue when it comes to brake masters or booster. Is there a way I can find out if it's the booster or if it's the master? The vacuum line going to the booster isn't kinked or blocked. The fluid seems fine as it was flushed out before the car was put on the road a month ago. All the brake lines are in good condition, calipers all seem good and the pads are new and rotors are fine. Could it be that I boost my car and there is too much pressure going into the vacuum like into the booster? Before they started locking up I have it a boot a block earlier?

Thanks everyone even the funny comments haha. It has only happened twice and when I leave it for half hour it's all good again. I don't think it would be piston because all brake calipers lock up, not just one. I'm going to get another brake master cylinder and see how it goes. Someone said it could be air in the master?

I don't know if the brake booster is helping or not. Is there anyway to test it and see if it the booster or the master?

Hey everyone, I was driving home today and all of a sudden my car started to pull back like the brake pedal was pressed but it wasn't. I continued to drive till I could drive till it was safe to pull over. I got out and checked the brakes and the front rotors were smoking on both sides and rear. The pedal is hard to press and stays the same when car is off or running. It has been sitting for half hour and now it's gone. A month ago the same thing happened but not as bad and I thought it was low fuel so out more in and it was fine. Does anyone have any idea what the problem is? It doesn't happen all the time.
