Thanks for the advice. I will bleed the brakes. I have been using the recommended SRAM DOT 5.1 brake fluid. I switched from SwissStop Exotherm2 brake pads to DiscoBrakes sintered steel pads after a pair of SwissStops wore out in about 500 miles last Fall. The Exotherms have heat sinks and may help preventing the pads/caliper/line/fluid from overheating. I just ordered another couple pair and hope that the pair that gave out so quickly were a one off.
