Most-not all- times that I stop, the ABS kicks in. HELP!!
When I stop at a light, or pull into a parking space, the ABS system kicks in and the van won't stop. There are no dash lights that come on when this happens, and it is happening more frequently, I can almost count on it every time I stop now. When I feel it start to happen, if I let go of the brake and then reapply it, the brakes will work normally. Lately it has been getting so bad that the brakes won't release sometimes and kind of lock up and I go an extra 10 feet -- very dangerous! I have had about 4 different people look at it and some say it's the ABS module, but they aren't so sure because of the light not coming on, and the ABS still works. I have also heard it could do with the individual sensors on the wheels, and one person even said something about the power steering pump being involved. A tire place hooked up their computer when they were driving it, and their computer did not register a problem. I really need to get this fixed, and I don't mind paying for the problem, as long as it's the right thing.

Something is wrong with your statement
it is a 99 caravan 3.3 no abs , then you are on about abs light pump etc
the abs pump only works when the master cylinder is under pressure and that pressure is suddenly reduced by the sensor reading a locked wheel and a valve is opened to release line pressure to that wheel As soon as that wheel starts to turn, the valve closes
while the wheel is stopped and that valve is open , the abs pump kicks in to maintain line pressure otherwise the brake pedal would go to the floor
master cylinders work through a. abs unit and not because of it so if the master cylinder becomes faulty, the abs pump will not operate until a wheel stops turning as there is no line pressure to stop a wheel turning
the abs light may not be on because there is nothing to operate the system to put it on
yes your right it's abs kicking in , if you look on control moudule next to or just below master cylinder there will be a 2-3 wire plug ,pull it off and see how brakes react DONT TEST THIS ON ROAD ,try it in a safe place at controlled safe speeds if they seam to work fine your abs control module has problems when you do this your ABS light will come on .hope I helped .
Well, it could mean that the emergency brake has not been fully released.The ABS system light is on if something has occurred within the ABS system. Something faulty may have happened there, get it checked out!
First thing with brakes is to check the lining thickness. You can usually see the fronts through the wheel, or look underneath. If you have drum brakes in the back there may be a rubber inspection plug.
But if linings are ok, another risk is wheel bearings. You would then feel it as a vibration in pedal, and through steering wheel if a front bearing.
With the light, have the ABS code read with a ODBCII module. Autozone can do this for free.
Hello there: There is a abs wheel sensor that is on the hubs on these vehicals that should be changed if the light that you are getting comes and goes this happens when the signal from the sensor to the abs system has been interupted you can take it to autozone and have them clear the code for you till you can get this repaired these sensors can cost around 150 to replace ok
