I had a similar problem once with my Audi. All four wheels would lock
after about 20 minutes of travel. It seems that a problem was that my
"mechanic" filled up brake reservoir with wrong type of brake fluid,
that caused problem with rubber seals, and return spring was not able
to return cylinder back. I changed master cylinder and problem went
away.

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?
