Steph and Dud B Posted September 3, 2022 Share Posted September 3, 2022 This is odd. I lost my little IR thermometer when we picked up our Ollie and recently replaced it. I'm in the habit of checking the brake drum temps when we reach our destinations. On the last 2 trips my passenger side brake drums were registering 20-30 degrees higher than the driver's side drums (as measured through the wheel spoke openings). Here's the weird part. The driver's side and passenger side drums are different from each other, but consistent with their partner on the other axle on that side - within just a few degrees. For example, the driver's side drums might be 120 and 124 degrees, while the passenger side are 149 and 146. The first time I thought it was because the passenger side was in the sun for most of the trip, but that wasn't the case last time. TPMS reports all tires running about the same temp. We just had axle service due to a recall and I watched the tech do it. No inconsistencies there. The brakes are auto-adjusting Dexter. Steph has walked alongside the trailer while I'm moving it, listening for odd sounds, but nothing. The only thing I can think of, and this is a real reach: the passenger side airflow might be affected by the step box and those drums cool slower???? On our last trailer there was one drum that always ran a bit hotter than the other 3. Figured that one brake adjusted itself a little tighter than the others, but I've never seen this happen in pairs on different axles before. Very strange.
