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.
