Brake pulse
I have a 97 Expy, 4WD 4.6. 130K. I am getting an intermittent (usually within first five minutes of driving) brake pedal pulsation, feels like the ABS system kicking in. Later, the ABS light comes on. When the pulse hits, you can hear that ABS sound, but the pedal is very tough to push down. Like the ABS is trying to work but it is not engaging. This is not during panic stops- it is just after like pulling out of the driveway. I have read some of these threads and notice a lot of talk about the rear speed sensor on top of the pinion - could this cause this problem?
