I have that first set. One Saturday I was replacing my rears, and literally got so frustrated with the little cube version you get from Pep Boys, that I tossed it into some woods. The little nubs could not grip into the piston face and kept slipping. It was impossible to turn it AND put pressure. (I've changed my rear pads about 3 times in the 8 years and 124k miles I've had the car. The amount of pressure required to turn and push that rear piston is never the exact same. Sometimes it turns and compresses easy, other times it takes a LOT of pressure and force. When it's the latter? YOu'll be SO glad you have the kit from HF or one like it.). A trip to Harbor Freight (4 miles away) just before they closed turned up the first set. Motor Trend/Car and Driver has a 20% off coupon in every issue every month, so used that. I've used the set above twice since then on different vehicles and it's a GREAT investment.
