Just had the guys at the shop pull my drums. Only one brake was working the other 3 covered in grease. Said I put to much in this spring. Metal on metal so don't over do it with grease
We had a wheel come off in Biloxi, Ms and broke the drum. That was after having brakes and backing plates replaced six months prior. Would have thought they took care of the bearings at that time. Unless you do it yourself, having a mechanic inspect the brakes and bearings every year sounds like a good idea whether you pack on the mileage or leave the rig sit for long periods of time in one place where condensation can get in.
