Oldsmobile/Buick Repair: Fluid leaks and Brakes, fluid leaks, cylinder replacement

Question
I drive a G.M. 1995 Olds, 4 dr. Special Ed. 98'
I am Not original owner - and don't know all the history. Found the car shifts hard between 45 to 55 wonder what can be done there; and Most importantly, Right front Leaking Brake fluid (driver frontside) light comes on to tell me brake issues; I fill container with brake fluid and it empties on driveway when parked in a few days; Note: I had right front caliper replaced a month ago and new pads; mechanic from Italy not really knowledgeable, I would guess He may have forgotten something at the time of the change to new caliper or that maybe a different issue here with the leak. What are reasonable charges this and what if something like a line or cylinder replacement is needed -just adding to the question -What is fair and reasonable to charge for parts and time?
If it's not the Right front caliper - May I ask what it could be ?

Thank you.
