Sometime ago I posted a problem with severe brake squeal following installation of Porterfield R4S pads on my 914-6 conversion car. I'm running Boxster calipers up front and the PMB widened calipers in the rear.
I've been able to trace the problem to the right front caliper. Since the other three calipers don't squeal, I assume that there's some sort of alignment issue between the caliper/pad combo and rotor. However, the caliper didn't squeal before with the Textar pads. The right side also locks up before the left, with lots of tire skreech and smoke, but nothing from the driver's side. Are these two observations related? Any suggestions would be greatly appreciated! |

Another thing you need to be careful about is the orientation of the notch in the piston. I don't think that's an issue with your boxster brakes though.
...another thought; did you replace the master cylinder when you replaced the brakes? Make sure both of your front feeder tubes are on the correct spigot on the cylinder. It is possible to swap a front to a rear tube. |
