<x-charset Windows-1252>Hi, I need to replace the master cylinder in my '65 Type 34. I picked up a couple NOS FAG master cylinders recently: 1. 311 611 021A - Brake master cylinder - 20.64 - single circuit drum brakes - to chassis # 221 974 and 365000001 - 365220883 for models 361-368 (Squareback) 2. 311 611 023 - Brake master cylinder - 19.05 - single circuit disc brakes - '66 or '66-'67 only, depending on the model (Type 34s went to dual circuit in '67, a year earlier than the other Type 3s, unless they had option code M139) My parts books lists my original master cylinder as 311 611 021B - single circuit drum brake - 19.05 Question: 1. Can I use either of these master cylinders? I have been told there is no problem upgrading to the Squareback 20.64 master cylinder by one shop I talked to. They said they actually only sell people the 20.64 one. 2. What's the difference between the 19.05 drum and disc brake master cylinder? There appears to be no physical differences. Internal valves? 3. Should I disassemble and lubricate the NOS master cylinder with brake fluid before installation? Both are in perfect external condition and the pistons moves smoothly when bench-tested..
