Hey paddock people,
Need brake rotors that will last at least a season. Heres the stats on my brakes 1976 911 5-lug 19mm master Hawk pads dtc-70 (front and rear) Zimmerman drilled and rotors I'm getting tiny cracks around the drilled holes of the rotor. I'm sure the Hawk pads are to blame. Under normal driving conditions I bet these rotors will last a good while. AutoX and Sebring is killing them. So....any good rotor ideas? Stoptech and Centric are out there for my 911 set-up. Anyone got anything to say on these or any other advice? (IMG:style_emoticons/default/biggrin.gif) Shane |

Yours are definitely worn. Most drilled rotors will have some chamfering around the holes to reduce cracking. Yours either didn't have those, or it's worn past the chamfering. I'd stick with blank rotors, or if you want to get fancy, use J-hook rotors.
Hawk pads can be tougher on rotors than other pads. I've tried quite a few pads and currently am running PF01 pads. They have good initial bite and are easier on the rotors. They tend to squeal when cold though. |

Without chamfering you end up with a hole with a 90 degree angle to the rotors which cuts pads; this is according to a big time professional mechanic and racer I know. We were going to cut the rotors on my son's MB compressor, but cutting the pads would eliminate the chamfer area. You'd end up with a 90 degree angle which cuts pads. Bought new rotors instead. |
