PFC pads squeaking - but only at high temps
I've had the PFC Z-rated street pads for a couple months now. They're quiet at normal operating street temps, but they'll squeak when I start to really get some heat into them. It's more of a dull, subdued squeak, rather than a sharp, piercing squeak.
I'm slightly confused because I'm accustomed to pads that behave in the opposite manner to these, i.e. noisy when cold but quiet when hot. Should I ease up when they start making noise, or is it safe to power through? I doubt I'm cooking the pads, since that wasn't a problem for me with the oem C5Z pads that these replaced.

Try bedding in the pads as it might help a bit. Here is a link how to bed them in.

I have used pfc quite a bit and found thier race pads to be pretty street friendly in terms of providing good stopping power when cold and being relatively quiet. Rotor friendly as well. I'd say don't worry about it.

Consider yourself lucky! I didn't think you could GET PFC-Z rated pads any more. Where did you get them? I ran them 15 years ago, but now I run Stoptech Street Performance pads for both the street (excellent cold bite) and light track duty (MSR Cresson, not Road america), they are good for 1300 degrees F.
How do the PFC-Z compare with the StopTech Street?

To ME the Stoptechs work better. The PFC-Z pads were a good street pad however, they were never intended for racetrack usage. I'm sorry I don't know what the max temperature was for the Z rated, but I don't believe it is 1300 degrees F. and my Stoptech Street performance pads do work very well at the temperature, as well as at normal (cold) street ambient temperatures.

Thanks for the info, I may look at trying the stoptech's after these wear out
