Discussion Overview

The discussion revolves around the issue of an unusually hot back left rim on a 2004 Honda Accord, accompanied by a smell of burning rubber. Participants explore potential causes related to the brake system, wheel bearings, and other mechanical components.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests that a dragging drum brake could be the cause and inquires about the last brake service.
  • Another participant recommends checking if the brakes are stuck and inspecting the tire for any unusual conditions.
  • A different viewpoint raises the possibility of a rusted parking brake cable preventing proper release.
  • Some participants propose that the brake system is likely the issue but also consider the potential for a bad wheel bearing or U-joint affecting the situation.
  • Concerns are raised about the tire possibly rubbing against another component, which could explain the burning rubber smell and heat.
  • One participant elaborates on various mechanical issues, including the possibility of a pinched brake line or stuck brake components, emphasizing that heat indicates a friction condition that requires inspection.

Areas of Agreement / Disagreement

Participants generally agree that the brake system is a likely source of the problem, but multiple competing views regarding the exact cause remain unresolved. There is no consensus on a single definitive explanation.

Contextual Notes

Participants mention various mechanical components and conditions that could contribute to the overheating issue, but the discussion does not resolve the specific cause or the necessary steps for inspection.

I've noticed on my 2004 Honda Accord that my back left rim gets unusually hot (hard to touch and can feel the radiation) and there is some smell of burning rubber. Any ideas?

Drum brake maybe dragging? When was the last time the brakes were serviced?
 
Jack up the rear, check if the brakes are stuck on. Check the tyre for anything unusual too.

Is there a noticeable noise?
 
park brake not releasing due to rusted cable?
 
As the other have said, my first thought is the brake system. I would not, however, rule out the possibility of a bad wheel bearing or U-joint.
Is there any unusual sound in your car? The smell of burning rubber, along with the heat, could indicate that your tire is rubbing on something.
 
hot rear wheel

there is a finite number of possibilities
car body rubbing on tire may cause rubber smell but not likely

running brake shoes or pads down to metal will do this but you would have heard the brake noise way before it welded in...hopefully...that is why disc brakes have wear tabs..

all rear wheels have wheel bearings which have a rubber bearing seal..should road salt or acid rain eat into t he seal and the bearing rusts we have friction,,easy to check
stuck parking brake or brake actuating cable may be rusted to the extent it freezes in the position where it will not properly release.
same may happen with rear disc brake pads if piston sticks in actuated position because the rubber brake hose is pinched closed..not likely as both rear caliper pistons would be effected..but..each rear caliber has steel brake lines that plumb to each caliber from the Tee fitting that the brake hose is connected to,,,.you may have a pinched brake line caused by running over some road hazard, thus locking a caliper piston in the actuated position
same can occur with brake shoe piston on non disc brake systems.
in all cases - heat is not a good sign and points to a friction condition. Some thing is causing this and inspection is in order..if car is rear wheel drive,,same as above can occur..if rear differential fluid is too low or not present you will hear major gear noise and bearing whine..

hope this helped
