My '74 2.0's PO put in 320i front calipers. I went to replace the pads and found that one of the calipers was frozen with the piston out (pic 1 below) and I cannot get it to move. Good news, he also gave me another caliper (pic 2). Bad news, the caliper has a spacer (for vented rotor?) and the flanges are not machined down. Good news, I can take the spacer out, bad news, don't I need an o-ring where the two halves meet? If so, where can I get them? I'm hoping with those that I can then put the halves together, get the flanges machined, and I'm back in business?

The piston can be pumped out using a grease ,thread a flexible (rubber)hose on to the grease gun for this procedure ,use a small G clamp to hold the opposite one from popping out.
Take care doing this as I once cracked a caliper half when the piston didn't come out straight (IMG:style_emoticons/default/sad.gif) . Yes you do need small 'o'rings between the caliper halves,a brake repair shop should have the rebuild kits or BMW should stock them. |
