Rebuilding master cylinder
Does anyone have experience rebuilding master cylinders?
Is this effective or is it a better idea to buy a new or remanufactured unit?

It can be done but a new master cylinder is relatively cheap and this is the perfect time to upgrade to a 19 mm master cylinder if you so desire. I think they are under $100 for the 19 mm unit.
Usually when a master cylinder goes bad it is because of contaminants in the fluid. The rubber seals in the M/C will last almost forever if the fluid is kept clean and dry. If you have crap or water in there then it will probably damage the cylider bore. A hone is only supposed to clean, not take metal off so if the bore is pitted or scored at all throw it away and buy a new one. If is is near perfect and dimentionally correct, you could probably throw some new rubber in and get away with it. |

I think that's good advice-I'd buy a new 19mm unit for around $100. While you're at it I think you must buy new grommets for the reservoir lines as they are not included, but I could be wrong. I rebuilt mine and after I installed it I could never get the thing to work-still not sure what I did wrong, the gaskets were all in the correct orientation. So after that I bought a new 19mm MC and never looked back.
