I recently had something really wierd happen with my '99 4-door, 4
wheel drive S10 Blazer. I was navigating the second, right-hand turn
in a pair of sharp, left-then-right turns while entering the driveway
to one of my local grocery stores when my brake pedal became extremely
soft and nearly traveled to the floor. Simultaneously, the red brake
light on the dash turned on. Immediately following the turn I had to
straighten out the steering wheel, and the brake pedal returned to
normal, and the brake warning light went out. Since then all has
worked properly whenever I've used the brakes.
The wierd part is that this has never happened before, and I have not
been able to duplicate the problem since. I have examined both front
calipers and hoses and all appears to be well. No cracks, pinch
marks, leaks, worn pads, etc. This truck only has 28K on the clock,
so the pads are not excessively worn. The hub assemblies are sound
and have no play, The master cylinder fluid resevoir is filled to the
"MAX" line, and was before this incident. There are no codes stored
in the engine computer (does the braking system do this anyway?).
Also, I do not recall the antilock hardware activating at all during
my final right turn. I know the kind of vibration it makes. Besides
I was on clean, dry pavement anyway.
I'll look a little further when I have some time. I have yet to pulll
the rear wheels and check out the calipers and disks there.
Still, I don't expect to find anything, and there appears to be no
loss of fluid (no leaks on ground, resivoir full). I would assume
that the hydraulics in this truck are cross-connected diagonally for
safety. Is this right?
Anyone ever have something like this happen befofe? What did you
