![]() My new tires are all the same size and all are Load Range E. The tire shop's work was not a contributor. So, it did it with the old tires, and it did it with the new tires. The original tires went about 102k miles, and this ABS crap started at about 95k. I'm running the same size tires as original, 265/75-R16. There shouldn't be any issues with tire diameter. I like to do the maintenance on my vehicles, but I don't crawl around, notice every detail, or remember any particular thing about it, unless I need to. He may not be 'in the mood' for any more that day. Kind of like a gynecologist when he comes home and his wife is feeling kind of spunky. I'm not an expert by any means, but I understand how they go together, and details about the parts that go on them. meaning, they're not much of a mystery anymore. And see ABS units sitting on the line along with all the I'm responsible for. My problem is, I see several hundred cars everyday. Now, don't assume I'm a dumba55 because I don't remember about seeing the ABS unit on the fender. I think so because a) I think I've noticed the pump / motor under the hood on the left fender, and b) I can hear that pump motor running when mines doing this at 5 mph or less. Gmctd - I'm going to guess that I have 4WABS. RWAL has the aluminum block with two solenoids on the bottom, under the master cylinderĤWABS has the pump\motor assy on the left fender, with all the steel brake pipes attached.Įither case, the CAB is linked to the PCM and ECM, and requires a scan-tool - have it checked for any fail code(s), and to see if the rear wheel tire diameter ratio is correct for your truck. I'm going to PM Infidel to get his input. The vacuum sensor makes sense to me because it seems to related to something electronic that has failed. So I replace the pads and that worked great. The old pads had a large amount of material left, but the squealers (or whatever the small sheet metal backing plates areas are called that start rubbing the rotor) had started making noise. I don't think I or anyone else has managed to get dirt in the sensors or effected them in any way. I didn't replace the rotors, because there was no shimmy indicating rotor warpage. The only thing that's EVER been done besides about 3 rotations & 1 set of new tires, is that I replaced the front brake pads one time at about 85,000 miles. My front end / brakes are about as virgin as they can be. He replaced a vacuum sensor near the fuse box on the driver's side. The only thing I've found so far with the searches that seems the most similar is an old post from Hyper. Seems like INFIDEL is the resident expert. I've been doing searches to try and figure this ABS problem out before I invest money into it. Should I replace the vaccum sensor? Hyper said it was near the fuse box under the hood on the driver's side? Let me know what you guys think and if anyone's truck is doing similar. I mean, the test lights come one whin I'm turning the truck on, and every thing works as normal, but I'm not getting the ABS problem light illuminating like everybody else I have read about. Oh yeah, I DO NOT HAVE ANY LIGHTS coming on the dash. Other than that, it does this about 75% of the time I am gently breaking, but there is no traffic in front of me to hit. ![]() But wound up like 5 feet away with some mild panic. The last 2 instances, I was approaching the red traffic light with traffic and decellerating to the light very gently (which is the only thing that saved those innocents in front of me) and had it timed where I'd be like 15 feet off their bumper once I came to a full stop. One time empty, one time pulling my 33' 5th wheel (and I almost whomped a lady at a traffic light), and one time pulling my enclosed trailer (again at a traffic light). ![]() ![]() Well actually I almost creamed one, the other 2 would've just been pounded. Not only can I hear it and feel it, but it causes the truck to not stop like it should. And the tires went 100k.īut now, when I'm almost to a stop and have slowed very gently and still gently coming to a stop, just before I stop (maybe at like 3 to 5 mph) the ABS unit kicks in (you can actually hear it running under the hood) and I of course can feel the pedal pulsing. I made the first set of front brake pads go 85,000 miles like this. Mainly when towing (because I don't drive it without towing much anymore), I try to anticipate red traffic lights, and slow early and gently at stops signs or basically anywhere. Hyper's problem was as close as I've seen, so I'm wondering if you guys have some guesses, and/or could tell me if you think his fix will work for me. I searched and from what I've seen, nobody has exactly the same problem. Its been a long time, but I'm back!Īs for my ABS issue. Alright - My glitchy computer is now working with DTR again. ![]()
