Abs Not Working

So I put on 33" tires and 17" rims about 10 months ago. This morning, some freak cut me off and I had to do some full pedal-to-the-floor breaking on wet, rainy roads. During this time, there was no pulsing of the ABS system. However, my brakes did not lock up. I know that adding bigger tires can mess with ABS, but I'm just checking. Is that how the ABS should work on my truck, or is the ABS not working at all?

Yeah.. i kinda got the same issue too...ive got 38's on 20's ..and after i drive like a mile or so.. the abs and brake lights kick on.. and when i push the brakes real hard.. they will lock up.

If your tires didn't lock up than there would be no reason for the ABS to activate. If your ABS was inop you would get the happy light in the cluster. Sounds like you should go up to a bigger brake set up...especially if you got 38's on 20's...have you had anything reprogrammed for the bigger wheel & tire combo?

The only thing that has been reprogrammed is i have a hypertech in it.. and ive adjusted the speedometer. I have a dyna trac rear end in it.. with the disc brake setup on the back.... what u suggest... i mean.. the truck stops ok for what it is... but in the rain and stuff... gets a lil iffy.

      OCI, not when but why?

      I imagine the cold winters up here with repeated short runs in town every day for those that live and work in town and given what I have come to learn on this forum with DI engines having fuel dilution issues, and if they don't change the oil until it says to but keep driving it for a while, I bet all that is just lovely on those finicky lifters.

      AWD conversion to Z71

      I just did some reading and Stabilitrak is more than a what I had originally thought. It is more of a vehicle control system to help the driver in precarious situations. I thought it was only the AWD system. Now I know. So I changed the title for this thread to AWD conversion to Z71

      Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.
