Steph and Dud B Posted April 16 Share Posted April 16 At least that's what my brake drums seem to think. We just returned from a 2300 mile trip to Hohenwald and back. Twice during the trip, after leaving campgrounds with gravel roads, we apparently had small rocks caught inside brake drums. The symptom was loud metallic scraping/squealing when braking. The first time, while trying to diagnose the problem in a parking lot, Steph actually heard the "ping" when the rock popped loose. A subsequent brake/wheel inspection at OTT revealed no damage. The second time it happened, the rock popped free before we were even able to find a place to stop. Now I'm wondering: I put rubber plugs in the 2 "adjustment" holes at the bottom of each of our "Nev-r-Adjust" brake backing plates. Our old brakes had plugs there. But, maybe I should leave those holes open as a path for debris to find its way out of the drum assembly? Any thoughts on that? Stephanie and Dudley from CT. 2022 LE2, Hull #1150: Eggcelsior.
