75% of ALL rotors thrown away are salvageable by turning/resurfacing. BMW reccomends resurfacing using a Pro-Cut on car lathe. Infact most OEMs require it for warranty brake work.
Thank you for this video, very detailed and educational.
Super helpful, thank you.
Question…is the .03 thickness deviation a universal number or only for BMW? Great video!
Did a brake job when I was about 25 years old on a Olds Cutlass. I’m 60 now. This was back in the early 1990’s. When I put it back together. One of the pins was stripped. It wouldn’t tighten up. Called a friend and he drilled it out and re-tapped it and put a healy coil. Worked great! Cost me a 12 pk of Bud. I didn’t know what to do at the time. Being youg and inexperienced. Buddy said he’d healy coiled head bolts with no problems and that it would hold. You know how a customer can be… they would assume you broke it and blame you and make you pay for it. I was already going to replace the caliper. Always something to learn. Luckily I had multiple friends that were professional mechanics. This friend of mine worked at Southwest Research here in San Antonio at the automotive division building engines. And still works there today as of 2026. All though now he’s a wheel. (Big) A manager in his department. Still have lots of friends that I can ask for advice or just send people to them if its too much for me or I don’t have the time.
Great video, I’m looking at replacing my brake pads and I always replaced the rotos. I might save some $$. No issues with vented rotors right?
