E350 Brake Question

Howdy, just a general question about brake performance (2002 Winnebago mini 24foot V10) Noticed on my last outing in wet road conditions, the ABS came on at a couple stop lights. New pads,flex lines, rebuilt calipers up front. Plenty of pad left out back. I even skidded a little when I stopped on a painted crosswalk. Not too strange but has any one else noticed this? I wonder if my proportioning valve is doing its job. I'm planning a brake fluid replacement shortly which will eliminate any air in the system, but I really don't think there is any air in the system. Thanks to all who reply.

    The easy inexpensive upgrade is brakes off a newer E350/450, 2008 or later model.

    Several outfits convert E-Series to 4x4, and the brakes/rotors/hubs/calipers are some of what becomes "take-off's." That, of course, would apply still more braking force to the front wheels. Or maybe I should say the Ability for More. Never do I feel the braking is now unbalanced with too much on the front. Instead, I've gone from "takes a lot of pressure, wish it had more brakes" to "there's always more brakes."
  • Drew - Thanks for your input too! I think you are right-I need to slow down.... No ABS fault light. Just the ABS actuator going on when I stopped too quickly on wet pavement. Appreciate all replies.
  • Thanks for the Input J-D. I now feel that all is ok, however I see why some here have upgraded to Brembo components and newer front end set ups. I may investigate some type of upgrades, but with your input I believe the system is functioning as designed. Thank you again.
  • Are you curious if it's normal for the antilock brakes to work when braking in low traction conditions? If that's it, then yes, that's perfectly normal and expected, and indeed why the system exists. It's doing its job and keeping you from skidding due to locking the wheels. It's also a good indication that you might be well served by slowing down a little in those conditions and giving yourself even more room to brake and maneuver.

    If you mean the ABS idiot light came on, that generally indicates some problem with the system, and diagnosing it pretty much requires as a first step reading the codes recorded with a code reader.

    I know for myself that there are plenty of times when I've thought there was better traction, based on general appearances, than there was and probably should have adjusted my driving a little sooner than I did. Thankfully none of these has ended in any serious trouble as yet. Rain just starting is one case that can make for surprisingly slippery roads, as the water lifts the accumulated oily gunk but hasn't yet washed it all off. Leaves, particularly wet leaves, are another that can readily fool people.

    Ours, will do that on even unpainted pavement if it's raining hard and I brake HARD. That's with nearly new "Rib" tires. That paint is Slippery When Wet.

    If it's not dragging or pulling, I doubt it's anything beyond "normal." Are any of your brakes much hotter than the rest after a drive? I'd suggest trying some hard braking tests on wet surface, out where you won't get in trouble if you skid a little.
