Cavalier 95 ABS/Brakes parking and lights no ON!

[kikemx]

I have Cavalier 95 2.2L VIN4 , I bought this car 5 years a go.

When I turn on the car in the instruments panel the ABS light and the red light parking brake didn´t turn on (this is from 5 years a go), the other light are ok (Engine, oil, battery and check gages)

Whe I turn on the car the brake pad vibrate and this is a signal that the ABS system is on, I guess that!.

For 5 years ago the ABS light and parking light didn´t turn on.

2 weaks a go the mechanical check the brakes and he founded that the wheels rear does not break, the fluid for breakes rear does´t appear but in the front brakes the fluid is ok, he purge the brakes and repair the modulator ABS y he said that fluid in wheels rear and front are ok.

I have some doubts about this system, because now when I turn on my car I hear the vibration (signal that ABS system is on ) but in sometimes when I turn right or turn left on road I again hear the vibration, what happend? is a problem in a sensor?.

Also the mechanical check the Electronic Brake control module and the ABS Control Module and he did not found any problem, I am very worried.

Please help me!

My brake pedal doesnt vibrate when i start the car...

The vibrating might be a suspension issue.
