I plan on taking my calipers off during storage thru the winter and having them powder coated. My question is how do I take the calipers of and keep my brake fluid from draining and not damage the lines by crimping them. I know I will have to bleed them regardless but dont want to do any damage to the lines and master cylinder if the fluid drains out completely. Also, would like to keep as much of the fluid in while they are off. As complicated as these cars are I would hate to do this wrong and cost more than just having them powder coated and a little bit of brake fluid.
A large hardware store has a selection of small rubber plugs in the drawers where screws and nuts are...I would think a plug in the opening would be good to stop the brake fluid from dripping out. There's no pressure there, only gravity.
I've had good success on all sorts of fluid lines by using a short section of hose slipped over the line and an appropriate sized bolt stuffed in the other end. If there is the possibility of leakage, I put a hose clamp on the hose.
In the case of brake lines, I use a very short piece of hose, so the bolt touches the steel line. That limits the amount of rubber deterioration from the brake fluid. When you get your calipers back, let a little fluid drain from the line to flush a bit before re-attaching.
