THE A.B.S-MODULE IS A NICE ROBUST UNIT,, BUILT TO TAKE GOOD PUNISHMENT,,, AND FOR THE PRICE,, IT IS A ALL AROUND WINNER!!,,, I TRIED IT ON MY ELECTRIC SCOOTER FOR MY REAR DISK BRAKE,, IN DRY WEATHER IT SEEM'S NO-DIFFERENT,,, "BUT",,, IN WET WEATHER IT WILL PULSATE UNDER HEAVY BRAKING,,, AND PREVENT'S WHEEL LOCK-UP,,,, I HAVE YET TO GIVE IT A REAL TRUE TEST ON HILL'S,,, AND EMERGENCY STOP'S ETC~!!,,, THE REAL TEST WILL COME IN THE WINTER. FOR THE SHORT TIME I USED IT IN WET CONDITION'S,,, I LIKE-IT!!!!
