I had to rebuild my brakes on my 73 GCBC and could not find the o-ring numbers anywhere including A.C.A. because the Gerdes went out of business, they are model A110-10. I finally found the numbers. Rainbow will sell you a 4 o-ring kit for $10 or you can order them individuallly for 45-90 cents each. Cost me like $7 to rebuild both. Here are the part numbers, X 2 if your doing both.
MS28775-008, MS28775-011, MS28775-014, MS28775-111
