Hi all,
I just bought some calipers from an early 80's BMW 320i for the teener. I've heard that they have to be machined slightly to fit. Does anybody know how much material has to be taken off, or the best way to measure how much to remove? They will be going on to a 74 2.0L. I haven't tried to install them yet, but I'm assuming that the mounting ears need to be machined down a little so that the rotor is perfectly centered in the caliper, correct? |

I machined mine down about 1/8". The exact number can be found with a micrometer.
I used a grinder to grind the ears down, then I used a very large, flat file to finish the job. I ended up with the ears within +/- 0.001". It toook me about an hour to do both. They work great! Good luck. Dave (IMG:style_emoticons/default/beerchug.gif) |
