December 26, 2015, 2nd test drive for Sambuca, my 1917 Canopy Express Delivery. I have been working on installing a Ruckstall rear end for over 14 months. On the 24th I conducted the 1st road test and found that the emergence brakes were on, so I have disconnected them and trying out Sambuca again today. Sambuca runs much better, but still having problems with Rocky mountain brake drum on drivers side heating up, after backing off several times. There is also a lack of power, compared to the way Sambuca used to run.
Have you pulled the wheel(s) to make sure something's not broken or loose in the drum, causing the brake shoe to drag?
If the axles and / or hubs are worn the brake drum can pinch the shoe against the backing plate and cause this problem. You can often fix the problem by adding a shim between the axle and the hub(s).
Thanks to Tim & Royce, for helping me with helpful suggestions. I plan on taking that wheel off and doing an inspection later this week.
ps: I can try and post some photos if that would help
Yes, please post photos, thanks!
