Howdy,

Vehicle is a 1990 full size blazer on 35s

Brakes are new, but it still won't stop worth a crap.

The only symptom it has is a "tssss" every time I press the brakes. (other than not stopping well) It doesn't keep "tsssing" if I hold the pedal down, but will do it every time the pedal is pressed. Does anyone know if this is a symptom of a bad booster? If not, could somebody point me to some other tests to determine if it is bad?

The calipers work just fine as do the wheel cylinders, and they are adjusted correctly.

Thanks,
Dan
