If those are the original 20 year old Toyota calipers, they may be binding.Ok, so I have a 1994 S4 that I bought in September [snip] get nothing for a little while and then it slows, but I gotta keep my foot in it, almost like the rotors are glazed maybe? The pedal is firm and not soft. Oh and the car already has ss brake hoses front and rear.
My 88 has what I believe are the original 26 year old Toyota calipers (BTW I'm using EBC Yellow pads on a daily driver Esprit - they seem fine). The braking feel on my car is just fine - hard pedal, good modulation, etc. But the brake system was also flushed heavily in 2011 and converted to SS lines (when I bought it) and flushed again in 2013 ( (18 months later). The difference at the 2013 flush was very dramatic; much harder and better feel - I may have an air leak in the brake system.
