Rear piston seal leak

[nova197]

2007 gt mustang with powerstop z23 evolution brake kit. Passenger rear was leaking bad from the ebrake bolt on the caliper so i replaced it with an oem one and both rear rotors and pads. Bled the whole system and made sure there were no bubbles in the hose. Went for a little test drive and immediately checked if there were any leaks.... and now the driver rear piston seal is leaking all over. I had to compress the pistons after changing pads but it wasnt leaking before at all. While compressing it i just kept twisting because i didnt know it had to be compressed at the same time. Would that destroy the caliper?.i just bought a new caliper but its gonna take a while to arrive. any advice or ways to fix this short term and safely?

Replace the caliper. If the seal is compromised then braking can suffer.

I have always replace calipers in pairs.

That's a given for hydraulics. The thought is that if one is failing the opposite side won't be too far behind.

Yeah i meant to and when all my parts arrived i was suprised to see only one caliper and realised the other one was never added. Thought i could get by until the other one showed up but NOPE
