Forged Billet Dynalite 4 Piston Calipers
FDL calipers are the newest and strongest in the class. Stress-flow
forging and a highly efficient radial transition body design are
key elements contributing to the superior strength and performance
of the FDL. The superior strength of this innovative caliper is
combined with proven performance features from other Wilwood designs.
FDL calipers are a fixed lug mount, opposed piston configuration
that generates high clamping force without deflection from four
stainless steel pistons. Stainless is used to resist corrosion and
reduce heat transfer. Square faced o-rings provide long service
life and decreased drag from positive piston retraction. Each caliper
uses Wilwood's SRS stainless steel bridge plates to eliminate 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.
Internal fluid ports eliminate all potential problems associated
with external tubes. Four corner bleed screws assure simple and
effective air evacuation from both sides regardless of mounting
position. The top loaded brake pads can be easily serviced without
caliper removal. Standard kits include calipers with Wilwood's signature
and a high luster black anodized finish. For custom show machines,
fully polished calipers are also available and guaranteed to catch
the eye and win the favor of the most discriminating enthusiast.
SRP or HP Series 12.19" Vented Iron
Rotors
Wilwood rotors are manufactured from premium
grade, long grain carbon iron to provide long wear with high thermal
stability and resistance to distortion. The superior heat absorption
and dissipation qualities of a vented iron rotor are essential to
preventing heat fade and realizing the longest service life from
the rotors and pads. For custom, show, and performance sport driving
applications, SRP rotor kits offer the enhanced look and performance
of a specially engineered directional cross-drill and face slot
pattern. The venting and cleaning action of the holes and slots
will reduce pad glaze, dissipate surface heat, and minimize irregular
friction compound build-up on the rotor faces. The results are smoother
engagement with an overall improvement in consistency and response
from the pads. Each SRP rotor is treated with a silver zinc wash
to prevent rust on the areas of the rotor not kept clean by pad
contact. HP rotor kits include precision machined smooth face rotors.
The additional mass of the non-drilled HP rotor will extend rotor
life on competition and other vehicles subject to higher sustained
and peak operating temperatures.
PolyMatrix Brake Pads
PolyMatrix
brake pads give fast response, high resistance to fade, long wear,
and the low rotor abrasion that PolyMatrix is so well known for.
Pad compounds are specifically selected for each application and
are listed in the service parts guide for each kit.
Internal Parking Brake Assemblies
Mechanically actuated twin shoe systems are neatly hidden inside
the hat section of the rotor. This method provides the best holding
power without clutter or rattle. Parking brake cables are relocated
close to the axle tube adding wheel clearance and reducing visual
impact. Parking brake assemblies shipped with kits are pre-assembled
for easy installation. Some noted kits will retain the original
equipment parking brake assembly from the vehicle.
Important Ordering Information
Custom built or narrowed rear axles may use axle bearings and flange
offsets that are different from the original make and model of the
center section. All kits must be ordered based on the housing end
flange and axle offset. Fittings and flex lines to install these
brake systems must be ordered separately. Some OE parking brake
cables may not be compatible with Wilwood kits. Custom cables and
hand brake kits can be ordered directly from Hot Rods USA at 1-888-875-6666.
