Re: 1987 BMW 325E Brake Pressure Build Up

Brake master cylinder would not cause this.

What are the EXACT symptoms you experienced? 'Brakes lock up' is a pretty vague description.

Going by your current symptoms, it's nothing more that a seized caliper.

I am experiencing a problem where the brakes lock up after about four
to five miles of travel. I was told that the problem could be
resolved by replacing the master cylinder. I did, but the problem
continues. The only way to get going, is to release the pressure via
the bleeding valves. This works sometimes for an eighth of a mile or
sometimes up to ten miles. I removed all the relays from the ABS unit
with no luck.

Is there someone who has experience this problem? How was it resolved?
