Finished my brake rotor machining setup
With 3 of these cars all using expensive brake rotors, and two of them with thick, but pulsating rotors, I've been working on a setup for the milling machine in my garage for turning the rotors. I finally got the last piece done and cut a pair of rotors today.
Like the phrase when all you have is a hammer, everything is a nail, when all you have is a vertical milling machine, every lathe job gets done on the inverted vertical spindle lathe. It's nice to have smooth brakes again. |

Taking appointments? Lol
Brakes are fine but stupid vibrations are annoying (and confirmed from rotors)

This would be cool to have in a dream garage, but in reality who's got the space.
My solution for vibrating / warp-prone rotors: cryogenically treated, high-carbon rotors. Tried it on my truck and it's solved my problem for the past 2 years. Granted, they are more expensive than cheap offshore made rotors (actually, I think my cryo rotors were made offshore!), but to me it's been well worth it. And I use no garage space |

Yeah, I understand the leverage, which is why I keep the cuts relatively light. I don't think the spindle bearings are in top shape to begin with. I got the machine used from a railway maintenance shop for $400, so I can't really complain. |

Bearings aren't even that hard to swap on those anyways. Easier than an x-drive oil pan. Ask me how I know. |

I've done a RWD pan gasket. Have to do the wife's soon too. Glad I don't have that axle and transfer case to deal with. |
