I HAD A PROBLEM WITH MY BRAKES, I WENT IN TO BRAKE O TO HAVE THEM LOOKED AT. THEY CHARGED ME $25.00 FOR AN INSPECTION. THEY SAID I NEEDED A POWER BOOSTER. THERE ESTIMATE TO REPLACE BOOSTER WAS $529.00. I BOUGHT THE PARTS FOR $65.00, AND HAD A FRIEND DO IT FOR FREE. IT TOOK HIM ALL OF 45 MINUTES TO COMPLETE. MY BRAKES ARE NOW FINE. THEY WORK BEAUTIFULLY. BRAKE O SHOULD BE RUN OUT OF BUSINESS.
