OEM brake specs?
OK, just trying to figure out where my pads and rotors are at. Can someone tell me:
1) What's the minimum recommended pad thickness front and rear (Z4M) 2) Maximum "lip" on the rotors before I should be looking to replace them. Front rotors have a 0.019 lip at present. Thx |

It's not a 'lip' spec, but a overall rotor thickness specification.
As stated above, the minimum rotor thickness is stamped on the edge of the rotor. Normally, for the Z4M OEM rotors (ATE), the minimum front thickness is 26.4mm and the rear thickness is 18.4mm OEM rotors start out at 27.2mm and 19.6, respectively. |

I know the wear sensors would let you know when they are toast but I was wondering how close I am getting to that point. I have the wheels off now and just bled the brakes but wondering if now is a good time to do the brakes or if I am good for a while. For the rotors, funny...I wasn't thinking of thickness, I was more concerned about the lip. I should have thought of that...brain fart. Thanks for the reminder. |

That is entirely possible. They might be making them a little thicker now??
The new Zimerman fronts I received have exactly the same dimensions of the ATE's |

Funny though, the numbers that are stamped on the rotor hats do not match up to anything relevant to these numbers. |

Interesting.... I always went by the specs on the hats.

You'd be surprised how many USED BBK's I show up on classifieds, you could easily snag one for half price. Check m3forum and bimmerforum (race parts and brake classifieds).

Now I have a question.
If you buy a used BBK, how do you know they are good? Do you have to search for a rebuild kit? Do you have to rebuild it? I am not adverse to using a 'second hand' brake system, but how do I KNOW it's good? |

The only parts I'd get new when buying a bbk is stuff like new crush washers, new bolts for brackets, etc but all that stuff is relatively cheap. |
