Ok, here's one for you experts out there.
I have a '99 4-door Blazer (4.3L) with just under 30K that seems to
have a squashy brake pedal. I say "seems" because 1) I have nothing
to compare it to, and 2) The brakes still stop the vehicle reliably.
I would just expect a firmer pedal from a vehicle this size.
Today while parking, I noticed something I thought was kind of wierd.
While sittng in any gear, stepping on the brake pedal hard causes the
engine idle to increase about 100 RPMs. If I do it 3 or 4 times, I
can raise the idle speed from around 500 to 900 RPM. Is this a normal
function of a vacuum-assisted brake booster, or do I have some kind of
Thanks for any assistance,
