I hve a mazda b3000 1999 80,000 mi 6cyl 3 litre I replaced calipers and rotors. When the car is not running I hve break pressure with a couple of pumps. As soon as I turn trk on I loose break peddle pressure and peddle travels to floor where I can get break pressure but only in that position with peddle at the floor there dosent seem to be any leeks and the master cylinder fluid stays good. Abs and break warning LTS are operating normally. Whats going on

If the pedal was good b4 u started, it's airbound and you need to bleed the calipers of all air! Open the bleeders and let fluid drip out for a minute, don't run out of fluid in the Master cylinder. After you get fluid out of the bleederclose it then pump up the brake pedal. Let me know how you make out. The other thing to check is as you look at the bleeders they are on top? If not you have them mounted on the wrong sides!
