Just put in a set of new front brake pads on my 2000 5TH GEN. No leaks or crimped lines. Problem is that there is absolutely NO pressure at the brake lever, even after minutes of pumping trying to get pressure back. Brake worked perfectly prior to starting the pad replacement. Other than pushing back the the old pads and calipers to allow room for the new pads and sliding the pads into place nothing else was touched. I've done this job before on this bike, not to mention at least a dozen pad changes on various cars, and never run into this problem before. Anyone have an idea what might be wrong?
