I did a search, might not be using correct word search, and this might have been answered already.
I will start by checking my check valves and abs relays. But for now, id like to go ahead and see if it could be something else.
Got my truck hm today from a job site about 20 miles away. I did my post trip, checked my tires, axles, fluids and so on. I didnt notice/feel it when i got hm, but i needed to get fuel and tobacco products, so i drove it to the local buc-ees, went in for water and cigs, came out and noticed a brake/clutch smell from the L/F steer tire. I checked the hub flange and rim and they were very hot to the touch, so i decided to check the drum and steer knuckle, even hotter at the drum. I proceeded to check the remaining 5 hubs and the R/F steer, both intermediate axle hubs/drums were warm, but nothing more than normal usage warmth. The rear axle hubs/drums were much warmer than the intermediate hubs, but nothing like the L/F steer hub.
I poured a couple bottles of ambient temp water on the steer drum and it steamed and boiled. I limped it home and when i shut it down to check the drums, the l/f was lightly smoking, so as a precautionary, i got the water hose and proceeded to cool the hub down first for about 5 min, then moved to the srum and i could hear the water boiling and steam was so thick, i could see the tire bc of it. After i got it cooled down to the touch, i moved to the rear axle and repeated. Steam didnt roll out like on the front, but there was a small amout of steam, even at the 3rd member.
Im gonna check diff levels tomorrow too, but i know 100%, there was ample gear and lucas oil in all 3 axles but i did notice a weep starting at the output flange seal the faces rearward on the 3rd member. My vent might be clogged, but it was working just fine several months ago when changed over from greased to oil bath bearings on the drive axles.
Thoughts, theories, causes on the service brakes sticking? Maybe need to pull the wedges out and lube them, or maybe a broken return spring?
