It seems that every year PFC Brakes is releasing a new rotor or caliper, and this year was no exception. Every time they come out with something new, its not just a color or slight design change-they’re actually improvements that make a difference while racing and out at the track. This time around, PFC showed us their new ZR94 and ZR24 calipers.
Based on the already successful ZR34, PFC took that as a starting point and made some huge changes to it. The biggest visual change was the removal of the external crossover tube on the caliper since the new ZR94 now features all internal fluid passages. This means your brakes are more protected from debris and even wheel changes since you no longer need to worry about damaging the crossover tube when removing or installing wheels.
Of course the ZR24 was show as well and although it uses a smaller rotor, it still has the same braking force as the ZR94 but has an advantage of being lighter since the caliper and rotor are slightly smaller. The ZR24 caliper also features internal fluid passages. While talking with Chris Dilbeck from PFC about the new calipers, he said, “It’s been winning a lot of races, and it’s gonna win a lot more now that the other racers see what these guys are running. The secret is out.”
The new calipers also feature insulators on the internal pistons which help reduce temps-results that have been proven in real world applications during their testing. There are also two finishes available for the ZR94, nickel plating and standard anodized. The ZR24 is only available with the anodized finish. Both calipers still utilized the existing V3 rotor design, which requires no bolts or safety wire which increases reliability and reduces upkeep and service all while keeping weight to a minimum.
The ZR94 and ZR24 also have increased the bleeder valve sizes to reduce breaking or stripping making these calipers easy to service. PFC remains focused on not only stopping power of their brake systems, but the release of the system as well. Power is precious, and PFC Brakes try to remain as efficient as possible.
