I was advised heat would be the last option followed by 100 psi to possibly pop them lose or soak everything in tranny oil. Thought diesel or kerosin would be better then replace the seals. What's best?
Use a grease gun, just take the nipple adapter off and you should be able to get a couple threads into the caliper. I've done this with several seized pistons on LCs and it's worked every time, even on heavy rust. I'm just not sure all grease guns have the same end.
