My '91 4Runner supposedly has Rear ABS.
Whenever I start it up the little Rear ABS light flashes on then turns off, which I assume means they are functioning...
How can I tell if the ABS is working?
I've never felt them pulsating, even when braking hard.
My brakes seem to lock up very easily in wet weather conditions.
Part of this is due to my very worn tires, but shouldn't I at least feel some sort of brake pedal pulsing or something if ABS is working and brakes are locking up?
