teched 30 Posted August 3, 2020 Share Posted August 3, 2020 This is not my truck, but it looks like the "can" on my truck. Looks kind of like air brakes but could it be hydraulic? Quote Link to post Share on other sites

mackaholic 55 Posted August 3, 2020 Share Posted August 3, 2020 Not hydraulic, definitely early s-cam air brakes. With Wedge brakes the air pot bolts right to the backing plate. None of the operating mechanism is visible. 2 Quote Link to post Share on other sites

mackaholic 55 Posted August 3, 2020 Share Posted August 3, 2020 Those don't have spring brakes so the shoes might not be stuck to the drums, maybe. Back off the slack adjusters and see what happens! If they are stuck and you can get the slack adjusters backed off sometimes you can break the stuck shoes loose by hammering on the drums. Might need to use a large drift punch to get to them. Best of luck! Quote Link to post Share on other sites

teched 30 Posted August 4, 2020 Author Share Posted August 4, 2020 I believe they dragged it to its resting place with a tractor... So maybe it will roll. By the size of the tree I say she's been sitting for 20 years or so. Quote Link to post Share on other sites
