Last Sunday
I helped the optometrist put new brakes in his truck, the left brake was dragging. And it was still dragging afterwards, so this sunday we ripped it apart again. The brake line was rusted and nearly collapsed, and the aluminum caliper sticky. So I replaced the rusted line and unstuck the caliper by compressing and expanding it several times, and then I hung out the side of the truck and watched/listened to the brakes, and tweaked until everything stopped and nothing dragged.
I’m probably a little old to be hanging of the side of a pickup bed by one arm and one leg while another guy drives it around, but common sense has not been my milieu for years.

Do you ever wonder if there’s someway to reward your guardian angel for rescues above and beyond the call to duty? Don’t be surprised when you discover you have had more than one.
Heck, my guardian angel quit and filed for disablity decades ago!! Og, it’s nice to know that even at our age we still hold on to some vestages of youth!
I wonder if there’s some way to attach a decent microphone to the exterior of a vehicle with a Go Pro vacuum mount.
I don’t know if there’s an easy way to avoid wind noise, though, or filter out road noise and sound transmitted through the body panels. Which sounds like a job for frequency-specific filtering software.
Exercising the Caliper? 1-2-3-BEND. Haha.
You could have exorcized the offending caliper, but Holy Water in the brake lines prob’ly ain’t a good thing.
