Here is the latest. First, bled the brakes. No good. Next, replaced front left and right flex brake hoses. No good. Replaced both front calipers. No good. Next, did a bench bleed on the master cylinder. This helped a little, the brake did not lock up but the pedal was on the floor and the brakes spongy. That may be why. We bled the brakes again and then again. Still the pedal goes to the bloor and remains spongy. Guess the next step is a new master cylinder. We are not sure of the year or make. Can this be found by the number stamped on the bottom of the master cylinder or is there another way to find out.
