spent 7 hours on the M5 yesterday removing useless wire from old hardwired radar detector and defunct alarm as well as an early 90’s era mobile phone mic. about 30 feet of wire total. also replaced all the parking brake parts except for the cables and backing plates. was finally able to fit the new parking brake shoes Ive had for over a year. I have the cables and backing plates but that would be way too much work for my limited skill.
