Brakes problem
1999 Ford Escort 4 cyl Front Wheel Drive Automatic

the front brakes are seizing up on this cart. The last time it did it it was the left front that seized up but the right front wasnt completely releasing. I have replaced the master cylinder and both front calipers and have bench bled the master cylinder and then bled all 4 corners of the car. They seize up after driving for maybe a half hour or so. This last time I test drove the car for 30 mins and every thing was fine. The the owner drove the car to work which was 10 min away and barely made it there. The master cylinder was replaced twice and the calipers several times and the brake hoses once. Any ideas help

Does this car have ABS? Has anyone check to see if it applying pressure? Has the hydrolic control unit been checked? Get back to me with what you know and I will do some looking to see where we should go first.

It is a non abs car. It has 4 ports coming off the master cylinder and it has proportioning valves on the two that go to the rear drums. I think I might have to adjust the push rod on the brake booster but I am not sure if this has one. I havent checked to see if the rear brakes have been dragging

I would not adjust the push rod. If it hasn't had a problem before the new master cylinder then I would check the master for problems and the power booster. I would first investigate the master cylinder as there are many options for this car. It is broke down as such there is with and without abs and manual or automatic trans. Now if they gave you the wrong master for the wrong option then that would cause this as the push rod and boosters would also be different sho check into this first with you parts store to make sure you have the right master on it. Then I would check the front brake hoses make sure they are not interenaly cracked and holding fluid pressure to the calipers and then check the power booster to make sure it isn't failing and pushing on the pushrod. Get back to me with what you find

It was an oem master cylinder that was on the caar and we changed to an aftermarket one we also replaced but brake hoses on the front end. The car was experiening similar problems with the old master cylinder but it would change sides after several months and that was after replacing brake calipers. When I checked the pushrod it was all the way back in. When I bolted up the new master cylinder I had to push on it to get if flush with the brake booster

You now have the push rod to tight you need to loosen it a little.
