Brakes locking me out...
My 2000 250SD is having some braking issues. Whenever there is the slightest bit of snow or ice on the road and i apply the brakes, no matter how slightly, the pedal will only move about a quarter inch, and the pedal shudders and makes a metallic "clink"ing noise but the wheels won't stop turning. I've slid through several stop lights and signs because of this. Its like the brakes reject the pressure i'm applying to the pedal. If this is ABS, they absolutely suck. Is there any way i can disconnect the ABS or override it??

i suppose you could remove the fuse for the ABS pump...
but i WOULD CERTAINLY NOT DRIVE IT until you can fix it or take it straight to the dealer... you don't want to be responsible for hurting or killing someone.

the calipers have nothing to do with the abs system what you need to do is take it to a place that can monitor the wheel speed sensors and determine if they are reading at different speeds, and then go from there, however you say your driving on snow well did you think that maybe your wheels are actually slipping? does it do it on dry ground? let me guess your extra vehicle was your winter car? these trucks are heavy and they need extra stopping space especialliy when the ground is slick

The extra vehicle was just for better mileage purposes. The truck is my main vehicle. The wheels could absolutely be slipping, but the problem is that if the pedal won't depress then i can't pump the brakes because they won't work. The ABS system is almost completely ineffective on icy roads, it 'pumps' the brakes too rapidly and will not stop the truck. I always give plenty of room when i stop on slippery roads because, like you said, its heavy and stops like poo anyway. I usually have this problem when i'm navigating tightly blocked back streets with stop signs and there's not enough room anyway. Its just that when the ABS kicks in, its like the truck starts sliding even less controlledly, and i'm now helpless. I like to be able to pump the brakes myself, and the ABS hinders that when it thinks there's an issue...so i was wondering if there's a way around them....Short of buying an older or ****tier truck or course.

OK, this may or may not have relovence to your braking problem. I use to own a 2000 Chevy Silverado when I was stationed in Anchorage, AK. During the wintertime the downtown area would often resemble an ice rink so studded tires where a common fixture. A few times I would come to a stop sign or light and whilst applying brake pressure from a good distance, the pedal would only travel a short span and the wheels would pulsate. I was quite literaly standing on my pedal with both feet. Come to find out the VSS senors tend to get dirty and would send the ABS a faulty signal hence the erratic operation. Took everything off and gently cleaned the bits with a brass brush. It helped with my problem, hope it brings you closer to resolving yours.

You could have a caliper sticking, when was the last time the brakes were done, and did you or whoever did them clean the slide pins and relube them. All it takes for the abs to kick in is for one wheel to lock or slow faster than the others. So on snow and ice it's amplified on how soon that wheel will lock up.
