FDL calipers are the newest and strongest in the class. Stress-flow forged billet bodies and a highly efficent radial transition design are key elements contributing to the superior strength and performance of the FDL. This innovative caliper incorporates proven performance features from other Wilwood designs. FDL calipers generate high clamping force without deflection from four stainless steel pistons. Stainless is used to resist corrosion and reduce heat transfer from the pads. Square faced o-rings provide long service and positive piston retraction on release. FDL calipers feature Wilwood's SRS stainless steel bridge plates to eliminate the bridge wear caused by pad gouging and extend the service life of the caliper. The spring-loaded action of the SRS plates also eliminates pad rattle and dampens the vibration harmonics that contribute to pad squeal. The 1/8" NPT fluid inlet is easily adapted to all types of flexlines. Internal fluid passages evenly distribute pressure to both sides of the caliper. Four corner bleed screws assure simple and effective bleeding regardless of caliper location. The top loaded brake pads can be easily inspected and serviced without caliper removal. Standard kits include calipers with Wilwood's signature and a black anodized finish. These kits are guaranteed to catch the eye and win the favor of the most discriminating enthusiast.
