I've pulled off the wheels and the dust cover to find some sort of pin holding the drum on, how do you take this off to get to the brakes? Also I've read there are two adjustment bolts that I might be able to adjust them back, but I'm not sure where these are? And the air bleeders are mostly round from the previous owner and seized up. I'm thinking I need to pull the drums, get to the brake cylinder and work on the air bleeder... | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy KMeagher, welcome, once the wheels are off there should be three slotted head screws in the drum face which you have to remove to remove the drum from the hub. You will probably have to back off the brake adjustment quite a bit to get the drums off, to back off the adjustment move the adjustment tool outer end from the center of the backing plate to the outside of the backing plate. You don't have to remove the hub to get the drums off, so you can re-install the "dust cover", hope that helps. | | | | | Joined: Nov 2006 Posts: 173 Shop Shark | | Shop Shark Joined: Nov 2006 Posts: 173 | If your drums are like mine, at least one of the three screws were frozen in the hub. I ended up pulling the axles to get the hub and brake drum off as one unit, one very heavy unit. This also gives you a good reason to repack the bearings.

I mention this because my dually's brake drum is one piece, it seems I have to take the axel dust cover off to get the brake drum off to access the brakes? I did find two brake adjustment bolts on the back side that seemded to release the brakes some, but I still need to get the air bled out, I like the idea of the dremel and flatening the sides some. Thank you | | |
