Brake booster rebuild kits available
Dang, wish I could have saved you some work by posting this a little earlier, but I was on the road.
A couple of guys got preliminary bits and pieces of the rebuild kits earlier this year, and the full kits are available now. ALL of the replaceable interior components for the M31 hydraulic brake booster are available, so you can repair a simple leak or restore all the seals in the entire system. I haven't figured out pricing completely, but everything came in fairly reasonable, after a long wait for the teflon seals from Denmark. A simple seal and o-ring will be $6 plus envelope postage for 2 ounces on your SASE. Will publish full kit prices and rebuild instructions shortly; email inquiries welcome in the meantime. unquote
