mmmmmmmm I reckon that is an odor that you will never forget 🔥
Years ago, when I focused on the parking brake on the '48, I too also had little information to work with other than knowing a local company could reline the practically bare band that I had...I assumed that they knew what they were doing when they asked what application the band was used on, but eventually realized that they riveted a lining that fit that they had on the shelf, which turned out to be too long and too thick [cue masculine punchline here]...with band adjustments out to stop the dragging, the parking brake did not hold, and not having anything available to trim the lining back, I opted to readjust to having a functional parking brake. So for a long while, driving that old truck around was accompanied with the smell of simmering brake lining...YUM...eventually the lining ends wore down enough that the brake worked as it should, but I can still smell those first thousand miles in that old buggy...good times
