Good point, and similar to the other current post about overheated caliper. Easy enough to check . I'm more sensitive to the hose issue because I also have a 67 BMW, and swollen hoses are not uncommon.Did we rule out the emergency brake out of curiosity? I wonder if in the replacing of the caliper, especially if you got a new rotor, maybe it got adjusted improperly? Just guessing, OP. Hope you figure it out!
