I recently purchased some backing plates for my rear disc brake setup that I'm going to bolt on here in a few weeks. I've now go to go buy a master cylinder. My question is: Is it okay to powdercoat the M/C? I don't want to have to take it apart to bake it in the oven. What is inside them that I could damage? I know if I want to powdercoat the booster I'll have to split the case and have it rebuilt after I'm done, but I was wondering what your guys thoughts were and if anyone has done this. Any thoughts???

Powdercoating generally is cured at 350-450 degrees.I think thats to hot for a master cylinder.I think it would melt the rubber inside.

Ditto for the booster. The heat will kill the diaphragm inside. It will have to come apart as will the master cylinder.

Is it hard to take these apart and put back together? Anyone done it?

Master cylinder you can take apart yourself ( I did it 8 years ago, so don't ask me how, but it was easy ). Have a pro do the brake booster. You may damage it otherwise.

The 2 halves untwist apart. There is a little hole in the wall place here in OKC, run by 2 men who have been around, doing rebuilding since the Civil War days. I have watched them seperate boosters for me and they have a press-like machine that the booster is placed in and then they twist it apart. By just watching them, it appears as though it would be very difficult to seperate the halves at home on the workbench.
From my point of view, for what they do, for the price (about $69.00), it is worth it to me to take one in and have it rebuilt. Of course, if you want the 2 halves re-plated, that is extra, about $40-50.

I've taken mine apart. It's fairly simple but a little time consuming. I clamped the bracket in a vice and tapped the tangs with a hardwood block and a hammer. Work your way around the diameter a little at a time.
