A simple screwdriver or anything with a point on it works fine to pry them out. I wouldn't worry about damaging them, as piston rings shouldn't be reused and are relatively cheap anyway.
i find the polished rings do not seal for a long time if at all. i use conventional straight lip rings.

If the piston rings are worn out you are probably looking at an engine rebuild. Without the proper tools and knowledge this would more than the average person could handle. Better off considering a new, reman or good used engine replacement.
Typically, especially in the early days of internal combustion engines, piston rings were made using specially hardened cast iron. Nowadays various alloys of hardened nickel/chrome steel are also used.
1. Tire iron to remove wheel 2. 17mm wrench to remove caliper 3. C-clamp or large pliers to compress caliper piston That's all :)
the tool you are looking for is called a piston remover, sold at every local auto zone As the rings in the piston wear on the wall of the cylinder, a ridge forms at the top of the cylinder. This has to be removed with a Ridge Reamer. It cuts the ridge down until the cylinder is smooth otherwise the rings in the piston would catch on it and the piston cannot be removed. Once the cylinder is smooth, you can tap the piston out using the handle of a wooden handled hammer. To install the piston back in, you use a Ring Compressor that squeezes the rings into the grooves of the piston. Put lengths of plastic tubing over the Rod Bolts so that you don't nick the crankshaft and tap the piston into the cylinder with the same wooden hammer handle.
19mm deep socket for wheelnuts, 7mm Allen wrench to remove caliper bolts, 8" c clamp to push piston back into caliper housing
You dont compress a piston with a C clamp, you use a piston ring compressor to compress the rings and tap the top with a hammer to sit it back in to the cylinder bore. The C clamp is used for compressing valve springs. *AArOn*
cast iron, grey iron. so its depend on u taht what strength u wants.
Worn piston rings allows the oil that is used to lubricate the cylinder walls to enter the combustion chamber.
On the outside of a piston near its top are two or more grooves that hold steel piston rings. The piston rings are used to form a seal between the piston and the cylinder. The material between the ring grooves is often called the ring lands.
I used a pair of wire cutters to remove mine.
