My 76 40 felt like it was pre loaded i.e. like the emergency brake was on. Checked e brake. Fine. Put the cruiser on jacks and found that the passenger rear and the driver's front wheel is very difficult to turn by hand. Other two wheels turn very easily with the correct drag one would expect. I do not have my manuals yet (due in this week) so I did not know how to adjust the drum. I found the inspection hole but could not really see anything. I have rebuilt drum brakes before so, I know the concept of the adjusting mechanism. I just cannot see in there/get a good position to see better (my head ends up between the spings. The disc brake looks operable from the outside, pads are good, little rust, no signs of leakage. I assume that if the calipers go, it is better to find a good used one as opposed to rebuild? If so, any cross references for them i.e. used on mini trucks or used up until year X? I have got to get pics up of this thing. It is not the best looking 40 by far but pretty amazing in that it is totally stock down to the H78-8 Dunlop snow mudders. And damn is it strong.
