I have a little more time. The problem with the spf design is it utilizes three cables. One cable from the ebrake hadle, and then one cable to each brake caliper back to the ebrake handle bracket for lack of a better term. 99% of designs use one cable which goes from one brake caliper to the other brake caliper via the ebrake bracket. This ensure you are always pulling evenly between the two calipers. It is possilbe and very very likely most spf are pulling harder on one caliper than the other. Once the pads contact the rotor on one side you cannot pull any harder and if the other cable is not adjusted properly it will not pull on the caliper brakcet to ratchet it out and therefore it never adjusts and before long as the pad wears you get less braking. Obviously if the ebrake handle cable bracket is loose all bets are off.

I have a 4 post lift so i could easily work under mine why the wife held the brake pedal down. I loosened the cable up to each caliper and manually pushed the caliper bracket back and forth. Intially it would rotate about 2.5 inches, by the time it ratched it out it rotated .5". The driver side only rotated .5" the whole time because the cable always pulled tight on it so it kept in in adjustment.
