When coming to a stop in slick roads the rear wheels contiue to push the car forward even though I have the brakes fully engaged. Over a year ago I replaced the transmission and ever since I have had this problem.
I don't know if it is a problem with the Transmission not disengaging or if it is a problem with the rear brakes not engaging.
In any event it creates a very dangerous situation, as it did this morning when the car pushed itself all the way through a icy intersection.

Re: Braking problem when the road is Slick
I would try first to separate the two potential problem sources by (in a safe place and on a slippery surface or sand) bringing the car to a stop, then pressing firmly on the brake and then following that with pressure on the gas pedal.
With someone watching the rear wheels, see if they are attempting to turn even though the brakes are applied.
No doubt that the transmission should be disengaging but it sounds to me as if the rear wheels are not braking at all.
I don't know if your car is so equipped but it was fairly common before the era of ABS systems that there was a regulator in the line servicing the rear brakes, some sensitive to the level (loading) of the car, others to the applied pressure and still others with both capabilities.
The purpose of this system was to prevent the lock-up of the rear wheels.
This regulator was passive and self-contained and rarely caused problems at all, but since they can control the pressure applied to the rear brakes, they might be capable of malfunctioning.

On vehicles equipped with antilock brakes (ABS), a second warning
light is provided to warn if a problem occurs within the ABS system.
The ABS lamp comes on when the ignition is turned on for a bulb
check, then goes out after the engine starts. If the ABS warning
light remains on or comes on while driving, it indicates a fault
has occurred in the ABS system.
What happens next depends on the nature of the fault. On most
applications, the ABS system disables itself if the ABS warning
light comes on and remains on. This should have no effect on normal
braking. Even so, ABS will NOT be available in an emergency situation
or when braking on a wet or slick surface.
CAUTION: If the brake warning light also comes on and remains
on while the ABS warning light it on, it signals a serious problem.
Your vehicle may not be safe to drive. The brakes and ABS system
should be inspected immediately to determine the nature of the
If the ABS light comes on momentarily then goes out, the nature
of the problem is usually minor and the ABS system usually remains
fully operational. Some vehicle manufacturers call this kind of
fault a "nonlatching" fault (meaning it isn't serious
enough to disable the ABS system).
Regardless of the type of fault that occurred to trigger the ABS
warning lamp, a special "code" is recorded in the ABS
module's memory to aid in diagnosing the problem. On some vehicles
this code can be retrieved by putting the ABS system into a special
diagnostic mode. The code is then flashed out through the ABS
warning lamp. The code number refers to a diagnostic chart in
a service manual that must be followed to pinpoint the faulty
component. On other applications, a special "scan tool"
must be plugged into the vehicle's diagnostic connector to read
out the fault code.
Those are your anti-lock brakes. Either there is a malfunction, or you are applying to much brake for the road conditions, which is causing the anti-lock brakes to activate. If the road conditions are slick and hazardous, slow down and start stopping sooner.
ABS light on likely means that one of the sensors is not sending the right signal to the ABS Brake Module. So, standard braking exists as a consequence. It should be less safe to drive with this condition, but can be driven if you pump your brakes manually on slick roads.
problem with the antilock brake system, this system prevents the wheels from locking up when braking, so you can steer while braking (hard or on slick road), have a mechanic check it out, most likely a sensor on one of the wheels are malfunctioning
you have a abs fault considering the year I of the van I would remove abs fuse or unplug the moduale to disaable it. the humming that you are hearing is the abs dumping pressure due to a false reading from one of the sensors or the moduale if you want to spend the money to make the abs work you will have to take it to a shop and have them hook up a computer to retreive the codes to diagnois the problem. keep in mind that with the abs dissabled the wheels will lock up when braking hard or slick roads let me know how you make out
First of all if your problem is only when it rains, get some tires for wet weather driving. Most cars have anti lock brakes now so you shouldnt have problems sliding to far. Your probably following to close to the car ahead of you. Give it the 2 sec rule. Put the car 2 sec in front of you. Another thing, Kia Rio's are light weight cars so if you slam on the brakes their is not a lot of weight on those tires to stop the car on a dime.
