TC 6R CALIPER
Caliper Highlights:
The TC 6R radial mount, six piston truck
caliper represents a complete new generation
from Wilwood. An extensive design,
development, and testing program resulted in
an extreme high strength caliper capable of
generating the clamping force and durability
necessary to handle the heavy loads of custom
and performance modified pickup trucks and
sport utility vehicles.
The foundation of the TC 6R is the FEA structural
analysis designed forged billet body. Premium
billet aluminum alloy blanks are stress flow forged
to produce a caliper that minimizes weight while providing
an extremely rigid and deflection resistant body. The bridge radius has been increased to accommodate rotors up to
a full sixteen inches in diameter. The bodies are joined and heavily reinforced with six high strength steel cross bridge
bolts. Cross bridge bolts give added strength against deflection and body separation at the high pressures and heavy
loads generated by the power brake systems on late model trucks and SUV's. Steel bridge insert plates provide
maximum load bearing protection against wear and gouging from the pad edges at all levels of brake force.
The TC 6R generates unmatched pad clamping efficiency through six thick walled stainless steel pistons. The heavy
piston wall adds one more measure of strength under heavy loads while the stainless steel resists corrosion and
reduces heat transfer into the caliper body, seals, and fluid from the pads. The differential piston bore design, taken
from Wilwood racing caliper technology, provides balanced pad loading with even wear properties at all temperatures
and loads. Piston bore volumes are matched for complete compatibility with the output volumes and pressures of the
OE master cylinders.
The total TC 6R package is capped off with rubber dampened fluid transfer tubes, recessed two-piece bleed screws,
and bridge mounted pad load springs. The pad load springs eliminate vibration and rattle while providing additional
dampening against the engagement harmonics that can contribute to squeal and other harsh brake noise. Choices of
either a signature high luster anodized Wilwood black, or a special multi-process gloss red coating, enhance the pure
stopping power of the TC 6R with a high tech style and custom look inside the wheel.
Radial Mount Caliper Adapter Brackets
Radial mount caliper adapter brackets provide a secure and accurate method of attaching the caliper to the mount
bosses on the original spindle. The brackets can be shimmed in two directions to compensate for production variances
in the OE spindles and hubs, to precisely locate the caliper over the rotor at the correct height for proper pad to rotor
radial alignment. The brackets are illustrated on the opposite page with a listing of availability for popular vehicles.
