Special O-Rings inside Calipers????????
Rookie mistake...I broke the seal in my brake caliper, instead of removing it 
, and after bleeding the brakes I developed air in the line. I never messed with the piston rings so my guess is the small o-ring that seals the two caliper halves isn't sealing any longer. I have a bunch of generic o-rings in the barn but I don't know if DOT4 brake fluid will dissolve them. I really don't want to buy a whole rebuild kit just to get one small o-ring. Does anyone know if brake fluid is likely to dissolve this ring? Going to go 
myself in the head now!
