Yes...the pistons just pulled out but you need to be careful to make sure they come out straight. If they tilt slightly, then they can get pinched. Again, patience! I did not have access to compessed air, but to me that might be easier and ensure even piston travel.
The new pistons and seals did push right in. I helped to use new brake fluid as a lube. the inner seals are shaped sort of like a "V". The point of the "V" is towards the top of the piston (the brake pad end). When you insert them, you have to "tuck" the outer end of the "V" into the cylinder. If this get folded up, the fluid will shoot right past. This is the part I mentioned before. The skirt is designed to be pressed outward to the cylinder walls and upward toward pads/rotor as pressure is added. The outer seals, for the corvette, had a metal ring on the outer diamter that was pressed (a hammer worked) into a groove in the caliper and the inner diameter slips over the piston.
In a world of constant change, it is the learners that shall inherit the future. For the learned soon find themselves capable of living in a world that no longer exists.
