hello everyone,
I posted earlier and forgot to mention this problem.
after 4 years of non operational, started the car and went for a spin.
in the highway, the wheel started to shake a bit, when exited tried the brake and didn't brake, I had to pump the brake few times, still didn't brake very good at all.
the next day when I started the car, the brake was fine.

has anyone encountered sucha problem?

thanks for help.

I suspect a locked up caliper or calipers. Three weeks ago, my right front caliper was siezed semi-applied. The car started to shake from the rotor getting hot and warping. By the time I got home and into my parking spot, I had a very poor brake pedal, nearly hitting the floor and the odor of burning brake pads was obvious. Brake fluid boiled. Next morning I had a pedal again since it cooled overnight. The car would barely roll in neutral from the caliper doing what it was. Replaced the right caliper, all 4 rubber brake lines and flushed the brake fluid. All is ONE with the universe.

Well after sitting for 4 years anything could be wrong.

You need to either remove the wheels and inspect the brakes along with all the lines for leaks, or have it towed to someone who can. Sounds like you have a leak, and probably a few other problems.

Tires may have flat spots from sitting too long. I am guilty of doing this myself sometimes.

yes, took it to tha shop, and placed in on jack, the wheels were locked up. I imagine the high gas millage is also a reason for this, right?

You have a sticky caliper. Just have one (preferably both) calipers either rebuilt or replaced and you should be fine.

I had the same problem on my Subaru. I took both front calipers off the car and disassembled them. I cleaned up the pistons and lubed them. I put everything back together and the shimmy went away.
