Thanks to all that have responded. I took a look at the seized left caliper. The inside piston was locked. Opened bleed valve and checked lines. All seems fine. Caliper was still locked. Could get piston to move for anything. Finally replaced caliper and now all is well. No noticable play in suspension. Will do better job of cleaning and servicing caliper on regular basis and see how it goes. If I get more heating or other symptoms of dragging, I'll just replace lines a suggested by lenore. Thanks again to everyone. You've been very helpful.

My '92 LS400 has had front brake problems for several years. The problem is intermittent. We'll occasionally notice vibration during driving that seems to be one brake or the other dragging. It goes away and then comes back randomly. Eventually, it gets more frequent and severe so we take it in and get the brake caliper and warped rotor replaced. It seems to help but within 2-4 months, the problem is back. We've now replaced the right caliper/rotor 3 times and the left twice. Tonight, we went for a test drive and the first mile or so was smooth and normal. Then, we noticed the pulsing/vibration. We stopped for 5 minutes and the problem was gone when we started back up. However, within a mile it was doing it again. Once home, I jacked up the front and the left wheel is locked. I'm wondering if we don't have an ABS/Traction Control issue that is the root of these problems. Anyone experienced this type of failure that can point me in the right direction? I thought to troubleshoot by disabling the ABS by pulling the 60A fuse but couldn't pull the thing. Any tricks to pull these monsters? Thanks.
