I have a 96 4x4 and the brakes work good if I step on the pedal normally. If
I do a "panic" stop or hit the pedal quickly, it's hard as a rock and they
don't work right away. Sorta feels like the engine is off and there is no
vacuum asssist but, no matter how hard I hit the pedal the brakes won't come
on for about a 1/2 second. Have vacuum at the booster and holds vacuum (how
much?). Replaced the brakes and fluid this weekend but, only because it
needed it. The problem was before that. I was thinking the booster, because
the engine changes when I press the pedal and the pedal will drop if I speed
up the engine. After reading Doc's trouble I started getting worried, except
that once the brakes come on I can stand on it and it stops like it should.
Thanks for any advice.
