| Post subject: | Disc caliper sliding bracket machining question |
I am in the process of rebuilding my front end with disc brakes and the junk yard spindle and caliper brackets I got are pretty corroded. The spindle is ok but the bracket sliding surfaces are corroded to the point where I have to machine the surface. How much can I machine off before destroying the geometry? 1974 Scamp. Thanks |

If you remove any material, you should use shims to correct the installation. I don't know any exact tolerance, nor do I have experience, but it's a textbook answer to your question. I can't actually say I've even heard of your problem before, although I can see your point. You wouldn't want your brakes binding. Perhaps, see what shims you can find and machine to fit if possible. Similiar to fitting overbored pistons. |

I've done that operation a bunch. I used to re-machine sliders and then have them nickel plated for wear. I had a fixture that held the caliper adapter square in the mill and then I just took a skim cut to get the suface nice and smooth. There is a lot of slop in the factory tolerances so no problem as long as you only take 0.015 or so off. I really recommend having the adapters plated when finished. Nickel should work the best for that application. They should last a long time once they're plated! |
