Take the pads apart and check for loose wires. Repair any broken solder connections you find. Since they do work sometimes, odds are if the connections are bad, they're just loose.
After checking and repairing the wires, remove the piezo sensors and scrape off all the rubbery glue that holds them in. Replace the rubbery glue with something more rigid like hot glue or epoxy. This will greatly improve the responsiveness of the pads.
