FlyingH Junior Member Offline SuzukiSavage.com Rocks! Posts: 55	Hot rear drum 07/20/20 at 10:48:20 After replacing my tire, I noticed (never checked it before) that my rear drum gets hot after several miles of riding with little or no use of the rear brake. Should I be concerned or is this normal? I can spin the wheel with no problem. Please advice.

Re: Hot rear drum Reply #9 - 07/20/20 at 19:54:24 Look at the brake actuation arm on the drum, push the pedal down, let off, make sure everything is working.. Probably not dragging the brake,but look.. I don't know what else to study,, unless the exhaust is blowing on it..

You need to take accurate readings of the temperatures across the drum. If its a bearing, you can find it,, Or, just go in and replace them,, You did keep all the spacers in their correct places,,
Harbor Freight sells an infrared thermometer,, may not be Exact,, but itll show if some area is hotter than another,
and youve Watched the rear brake actuator arm move freely away from the Brake Engaged position as you let off the pedal?

No heat problem on short rides, only on longer rides or with 2 people on it. This could be a bearing problem, but with only 5K on the bike that would be much to soon.

5K is low,, but,, theres a reason for warranties,, even new stuff fails sometimes,, I think youve covered about everything it could be, except a bearing,, Is it HOt on one side, more than the other? Left side/right side?

Have you made SURE the spacers are in the correct locations,, and the bearings have a spacer between them inside the hub?

No Extra Parts after having the wheel out?

Did YOU do the install or did you let someone else do it?
