lateral runout. your rotors or drums are warped and need to be machined or replaced depending on the thickness. if your slamming the brakes this is normal its your antilock braking system functioning as it should to keep you from sliding.
yes you can of you were asking "can you feel anti lock brakes pulsating" not sure why
Stop the car in a pulsating manner.
Change your brake rotor and brakes. problem solve
A 1998 Jeep Cherokee has disc brakes in the front.
Rotors may be out of "round" (lateral runout) and need to be resurfaced or replaced
A 2000 Jeep Cherokee would have rear drum brakes.
The grand Cherokee does have four wheel disc brakes. The wrangler and Cherokee have rear drum brakes.
Prevents brakes from locking by pulsating the pressure when you apply firmly so they don't grab.
It was an option
common sense Listen for squeaking and feel for pulsating when braking. Too much of either and you should have them looked at.
The ABS motor is pulsating which is applying and releasing the brakes to avoid wheel lock-up. This is normal.
My '96 Cherokee Sport does, so I bet a '98 does.
