Wilwood’s MC4 Mechanical Parking Brake Caliper is a multi-use, cable operated brake caliper that combines high output performance with simplicity in design and construction, and is the perfect solution for vehicle applications requiring a separate, mechanically actuated parking brake caliper. Built to accept rotors that are .810″ thick, with 11.00″ – 12.88″ diameter range, the MC4 combines an efficient die cast body with a forged billet anvil for superior strength under load, yet is lightweight at only 3.30 (2.95 without pads) pounds. Supplied with each caliper are our Composite Metallic (CM) high-friction, high static-hold brake pads, and are pre-fitted with noise cancelling shields.
This group of FDL Pro-Series rear disc kits provides a complete solution for popular muscle car rear axles that require a parking brake. Forged billet Dynalite four piston calipers, 12.19″ one-piece drum/rotors, and high friction pads provide optimized and balanced braking for all types of custom performance street/strip and show machines. The neatly hidden internal shoe system provides a clean installation with superior static holding power for parking. Optional caliper finishes and rotor designs enable the builder to personalize the style and optimize brake performance for every individual application.
FDL Pro-Series Front Hub Kits offer complete disc brake upgrade solutions for traditional non-ABS spindle applications on American muscle cars, vintage rods, and heavy weight drag cars. Based on the venerable forged billet Dynalite caliper, these versatile kits are easily optioned to suit the braking requirements and style preferences for a daily driver, serious competition, or the most discriminating show enthusiast. Most kits require no modifications for installation, and provide plenty of clearance inside popular 15″ wheels. FDL Pro-Series kits can be used with either manual or power boost master cylinders.
Wilwood’s Aero4 / Aero6 bracket mounts the Aero series of radial mount calipers to a 6.00” center to center lug mount. Brackets include studs, shim and the mounting hardware.
AERO6 calipers were designed for the specific purpose of providing big capacity braking with large diameter rotors for heavy weight and extreme duty vehicles. For cars, it’s the biggest of the big providing big brake performance for show and dual purpose street and track vehicles. For trucks and SUV’s, it provides big stopping power for towing, off-road, and enhanced braking with wheel and tire upgrades. Kits listed for specific vehicles are fully compatible with OE master cylinder output and ABS function. Directional staggered vane 14.00″ to 14.25″rotors provide maximum cooling for sustained high heat durability.
Wilwood’s HD Series Fixed Mount Rotor Hats have a long standing reputation for fit, performance, and durability. HD Series hats are manufactured from premium grade aluminum alloys offering high strength, low weight, and show quality appeal. HD hats have not only been a mainstay in many of Wilwood’s racing disc brake conversion kits, but they can cover a range of applications from an OE four lug axle shaft to a Grand-National stock car racing hub. HD hats feature a straight bell construction with a flanged rotor mount ring, Threaded-hole mounts for use with through hole rotors. When used with matching Wilwood rotor hardware, these hats provide solid mounting for a wide range of custom and competition disc brake applications.These features combine to provide maximum radial clearance between the caliper body and the hat. This can be a critical factor when trying to squeeze a large caliper inside a small wheel. Many hats offer multi-lug wheel patterns for added versatility. Some hats can be ordered blank for custom axle building and other unique applications.
Wilwood’s Rear Disc / Drum brackets kits (less caliper brackets) are manufactured from high strength aluminum alloy and use steel 5/16-24 clinch nuts for caliper bracket or accessory mounting. Fully populated with drum parking brake shoes, springs and adjusters. Will require additional caliper brackets to mount with 12.88” to 14.00” hat mount rotors.
Wilwood’s GP310 motorcycle disc brake caliper has been designed and engineered for use on 1984 to 1999 Harley-Davidson Motorcycles. Built around a 4-piston, high performance powerhouse, this billet aluminum caliper brings distinctive, bolt-on styling: Direct leg-mounted calipers are available for all single and dual disc models (except Springer and 4-speed FL models), as well as the 1983 XR 1000.
Rotor and Hat Register Adapters are used to locate 1 piece iron rotors and aluminum hat assemblies to vehicle specific hub or axle registers. Available in size ranges from 2.00” to 2.88” internal diameter. Requires 3.06” center hole with counter bore for installation into hat or rotor.
GT Series Big Brake Short Offset hats are precision machined from premium aluminum alloys for high strength and attention to minimized weight. Hats in this category feature threaded rotor mount holes for use with standard through-hole mount rotors. Threaded hole hats may also be used with T-Nuts or bobbins designed for use with specially machined slotted hole dynamic mount rotors. When used in conjunction with matched Wilwood rotor hardware kits, GT hats provide solid, reliable performance in the most demanding conditions. Short Offset Hats are for narrow space applications with offsets often less than 1.00″. They are available for most rotor bolt patterns in a variety of four and five lug wheel patterns.
Forged Dynapro Low-Profile Pro-Series rear disc brake kits provide a complete solution for popular muscle car rear axles on applications that require a parking brake assembly and extra clearance for 14.00″ to 15.00″ rim applications. Forged billet Dynapro Low-Profile four-piston calipers 11.00″ one-piece hat and rotor assemblies, and high friction pads provide optimized and balanced braking for all types of custom performance street/strip and show machines. The neatly hidden internal shoe system provides a clean installation with superior static holding power for parking. Optional caliper finishes and rotor designs enable the builder to personalize the style and optimize brake performance for every individual application.
Combination hydro-mechanical Parking Brake calipers use hydraulic pressure from the master cylinder for stopping power, and an internal mechanical lock within the caliper for a parking brake. CPB kits are built primarily for front wheel drive vehicles, and select rear wheel drive axles that are not well suited for internal shoe style parking brakes. The calipers are coupled with oversized two-piece rotor assemblies with aluminum hats and high friction BP-10 compound pads. CPB kits provide the correct balanced brake performance and matching style to compliment front big brake upgrade kits.
Wilwood’s GT 72 Curved Vane Spec-37 rotors are manufactured from a proprietary iron alloy developed to withstand extreme temperatures with the highest possible degree of resistance against distortion, warping, cracking, and wear. The formulation for this alloy is a derivative of technology and materials that were significant in the development of the extreme duty military spec rotors that are manufactured by Wilwood. Every Spec 37 rotor is precision machined to less than .001″ run-out, flatness, and parallelism. Combined with our proven GT Series asymmetrical face slot pattern and individual dynamic balancing, you are assured the smoothest braking available.
