Brake Caliper Keeps Seizing Sign In

So, we have a 2002 Hyundai Elantra 2.0L automatic, non-ABS with 70,000 miles on it.

I have never come across this issue before but the front driver side brake caliper keeps locking up about 10-15 minutes into a drive.

I've changed the brake caliper, master cylinder, flex line, of course bled the system, brake pads and rotors and STILL, it seizes. When it locks up, it's extremely difficult to change the transmission out of park. I am stumped on this one.

Any one have any ideas?

Did you twist up flex line into a pig-tail? That would do it. That or if that one gave you a really hard time you may have mashed it up and it might have developed a "Reed" effect letting fluid in but not out?

I didn't think this was available w/o anti-lock brakes? Do you have a yellow warning light for it when key it turned? It should,

You may have the push rod for the master cylinder set up with no free play at all. The pedal needs about a 1/4" of free play so the master can completely release. Otherwise it will build up pressure.

The next time the wheel is locked up try loosening the bolts that hols the master on so you canpull it away about 1/4" and see if that releases the brake. It happens at the left front first because that is the closest to the master.
