Hi,
I changed caliper two years ago. it works fine until 3 months ago. it start to leak even if I park the car. I plan to replace the caliper, but I notice the oily section on the rubber line (red mark). is it a sign maybe the line itself has some issue?

Thank you very much!

That whole caliper looks damp, hose everything off with some brake cleaner and see if you can pinpoint the source of the leak

Thank you for your reply. yes, it is damp. I didn't drive it in last 3 weeks, and by measure the brake fluid level, I can tell it's constantly leak.

is it how it should be done: remove caliper bolt, remove break pad, clean it up? Do I need to push the pedal couple of time maybe it will show leakage?

Thank you again!

Leave everything assembled for now. Hose it down with brake cleaner. Let it dry and then pump the pedal a couple times. Have a look and see if you can tell where it's leaking from.

2 years old and the caliper looks like that? In the future I would recommend going to RockAuto (or similar) and finding coated calipers to prevent rust.

You don't need salt to get that rusty, just un-coated parts
