Brakes problem
1993 Ford Probe 4 cyl Two Wheel Drive Automatic

hello to all... i own a 93 ford probe i replaced the master cylinder in the rear driver side drum (NEW)... then i began to bleed the brakes and lost pressure in all the lines. i checked the master cylinder under the hood just to find out that that was shot also so i replaced it, now when i bleed the brakes again the lines still didnt build up any kind of pressure what so ever there is also a slight leak coming out from behind the brake power booster, could that may be the problem... but is there any kind of feed back on any other possibilities that it could be so i can get all the pieces i need in one shot. thank you for you time have a wonderful day

HI there,

This leak must be investigated, you should not have any leaks whatsoever, you may have a faulty new master cylinder.
