1998 Plymouth Breeze 6 cyl Two Wheel Drive Automatic 207000 miles
Brakes were spongy and master cylinder dirty. So I changed master cylinder (used old resevoir) - bench bled. Brakes were more spongy (but worked some) and front brakes bleeder screws frozen. So I changed front calipers and bled all 4 brakes (in proper order). Brakes don't work at all now! Can't even risk putting in gear now because can't stop.
When engine off there is initial resistance with pedal depression (but goes all the way down easily). With engine on no resistance at all. In vehicle bleeding of master cylinder hasn't helped.
