Did they replace the brake hoses to the front discs?
If so, and if they forget to install new banjo washers, that's your problem.
Not that far front. It looked like a hair past the mid-point of the wheelbase where they flared it.
Took it back to the shop today. The tech said the brakes did not feel soft to him---and to be fair it was better since I did the "yank the parking brake a zillion times" thing. They cleaned, lubed and allegedly adjusted the rear drums. That improved things a bit more---but the pedal is still not _quite_ as firm as it was before the brake line replacement.
Will keep an eye and foot on it, but good enough for now.
