Thanks to my knowledge gained in practice with various aftermarket parts I easily saw the superior quality of this Automotive part over competitors. The Cardone 53 2720 Remanufactured Power Booster was installed on a Performance Car and has greatly improved the car`s braking power. No more hesitation when I need to stop quickly .The only con is that it's a bit pricey, but it's worth the investment for the added safety and confidence on the road..
