Re: 71 911 weak brakes

Ed, thanks for the reply. The S calipers have not been rebuilt. Brakes have deteriorated over time. They did get worse with a set of ceramic pads, and new rotors (the old rotors were a set of S aluminum rotors with Ferodo race pads.) Changed the Ceramic pads for Hawk Blues. Braking improved a little, but the pedal seemed soft and it needed a lot of travel to stop the car, and the pads ate up the discs. A new master cylinder seems to have fixed that, but I now have to put in a LOT of pedal force to get any braking effect. The calipers have been checked over by a Porsche race shop, but were not rebuilt, although they recently replaced one that had a pinhole, but it made no difference to the braking performance. The car does not pull. The changes to the car during this time were the RSR body mods, a 3.6 engine upgrade, and addition of the 17" Lindsey's that weigh a lot more than the 15" Fuch's. Any ideas, or if I upgrade, which direction should I go? I don't have any overheating issues with the brakes, they get hot, but I never boil the fluid.
