Kit Features
• 12.19" Smooth Rotors
• Forged Billet 4-Piston Calipers
• Engineered to fit your rear end

Built by Wilwood for Just Suspension, Dynalite Pro Series Rear Parking Brake Kits combine high performance braking, high-tech style, and functional simplicity for rear axle disc brake conversions that require a parking brake. Pro Series rear kits use Forged Billet Dynalite calipers, PolyMatrix brake pads, and iron rotors with integral mounting hats to engage the parking brake assembly hidden neatly inside. Whether it's a simple conversion from drum brakes, or an upgrade to compliment wheels, tires, or suspension equipment, these kits have it all. Check out the performance features and the options available in this new generation of rear axle kits from Wilwood.

Forged Billet 4 Piston Calipers
Available in Black or Red finish, our calipers are the newest and strongest in the class. Stress-flow forged billet bodies and a highly efficient radial transition design are key elements contributing to the superior strength and efficiency of the caliper. This innovative caliper incorporates proven performance features from other Wilwood designs. Our 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 life and positive piston retraction on release. Our 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 can 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 high luster black anodized finish. For custom show machines, fully polished calipers are guaranteed to catch the eye and win the favor of the most discriminating enthusiast.

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.

Vented Iron Rotors
12.19" vented iron rotors add stopping power and cooling capacity over smaller diameter OE rotors. Our 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 pads and rotors. In addition to their aesthetic appeal, the venting and cleaning action of the holes and slots will reduce pad glaze, dissipate surface heat, and minimize irregular pad build-up on the rotor faces. The results are smoother engagement with improved consistency and response at the pedal. Our rotors are treated with a silver zinc wash to reduce corrosion on the areas of the rotor not kept clean by pad contact.

PolyMatrix Brake Pads
PolyMatrix 7112 "T" compound pads are a low dust, low noise improved friction formula. "T" has fast response, high resistance to fade, long wear, and the low rotor abrasion that PolyMatrix is so well known for.

Caliper Brackets and Hardware
Aluminum caliper mount brackets with threaded steel inserts are lightweight and strong. The brackets are CNC machined for precise fit on each specific installation. Grade 8 quality or higher fasteners, washers, and alignment shims are included in each kit.

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.

Plumbing
Fittings and flexlines to install these brake systems must be ordered separately. You may add a braided stainless hoses to your order for just $50 extra.
