Q: Do I need to bleed the brakes after fitting these lines, and can your shop handle that?

You do. The page describes it as a simple installation, but swapping lines means opening the hydraulic system, so a full brake bleed afterward is not optional. That part is best left to someone confident working with brake fluid. If you are local to Los Angeles, our Hawthorne shop can fit the lines and bleed the system through the install request on the product page. A clean bleed is what actually delivers the firm pedal.
