Hello Everyone,
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 find?
