ABS behavior - impeding stopping distance

I've ran into this scenario several times now in Minnesota. We've received several small snowfalls (and one big one) so the roads have been a mess for over a week now.

 

In several right-hand turning lanes, the left half of the lane is clear.. either dry, or just wet pavement (no snow or ice)... the right half of the lane is still snow-packed. When I get on the brakes, the ABS kicks in right away because of the right side... however, I am not able to provide more brake pressure to the left side wheels that ARE getting traction... Thus it makes the stopping distance much longer than it needs to be, since the left hand wheels aren't anywhere near their maximum braking ability.

 

Are all ABS systems like this? I don't remember anything like this in previous trucks, but it could just be me.

Maybe they're afraid of it throwing the vehicle sideways if you get on
it too hard? Still isn't good though, when you could probably stop in a
normal distance with the side that is dry.

Dunno brother. All I know is that there have been times that I love ABS and other times that I hate it...

What year was your previous truck?

The system is able to tell wheel speed/slip at each wheel but it can't give too much braking power to the tractive side otherwise the truck wouldn't stop straight. ABS is only meant to allow for steering to still work, not reduce stopping distance.

      OEM Trailer Hitch Receiver - Impact tightened by shop

      Great info to have, I printed out what you had in your document as well as Newdudes post as I could see this mistake with the hardware happening very often if not realizing what type of special bolts are being used and just guess on bolt size for torque or the good enough "easy" method as per whack in the used bolts with an impact and send it !.

      Auto start stop disable

      By dennismc · Posted

      I installed the Auto stop eliminator on my 21 Sierra SLT shortly after I got it. They have a detailed video instruction on how, took me about 20-30 minutes to do. I was apprehensive too to start tearing apart a new truck but it was pretty easy install. Like you mentioned get some trim tools. I went to Harbor freight and picked up a set. If you can find some install videos/instructions to give you and idea for a plan of attack you should be fine.

      OCI, not when but why?

      If all oil manufacturers had to meet a higher standard for not just the initial filtering of the oil but that they had to improve on their formulation so that the oil cleaned the engine such as the Valvoline R&P or the new Mobil product ( assuming it works similar of course ), and the oil was changed on an interval based on good UOA data, there shouldn't be any gremlins running around like miniture rats on top of your heads to be washed down into the oil pan below 😁

      A while back on another thread there were comments and thoughts on air filters and I know that can tend to be a bit of a hot topic because of outfits that have a vested interest in selling aftermarket air boxes fitted with the gauze type of oiled elements touting the lower air restriction. However and unfortunately I don't know where I have seen the test results in the past about the amount of dirt through a test procedure that these style of filters do pass more dirt through than a properly designed ( not some cheap Chinese knock off ) paper/synesthetic media filter can do. Lake Speed had a conversation on that topic with one of the employees at Donaldson and there seemed to be a consensus of these oiled filters falling short in the absolute percentage of dirt holdback.    Which all ties back into how good the air filter is on the engine at keeping dirt out as that is going to reflect as a contaminant introduced into the oil as well as cylinder wear even if some of that dirt does find its way out of the exhaust rather then the crank case. Put another way that one can throw the kitchen sink at filtering the oil and using a bypass system which I fully expect will do nothing but good for the oils contamination but if the air filter system isn't doing its job then its preventing the engine from reaching the best wear/lasting case scenario instead.    Now perhaps this topic is or isn't for this particular thread but Grumpy Bear or anyone else for that matter, do you have access to some scientific trust worthy testing on engine air filter types to get some proper comparison data to post up.
