Assembling Wilwood DynaPro 6 Disc Brakes: Threads, Bearings & Rotors

In a recent project, we watched as a Total Cost Involved Pro-Touring IFS was installed. Onto the clip went a complete Wilwood DynaPro 6 big brake front brake kit. The Wilwood brakes are an add-on that can be ordered direct from TCI when you purchase a Pro-Touring clip. We recommend that you do so, as the Wilwood brakes are quality units that are designed to work with the TCI unit.
Since they come from TCI, the Wilwood brakes are assembled and ready to bolt on via the dropped spindle, but we will show you how they are actually assembled. The units in question are Wilwood’s DynaPro 6 forged billet calipers that are combined with 12 19-inch-diameter drilled and slotted rotors. They have been designed for traditional non-ABS-equipped American muscle cars and vintage rods. The units have six pistons to put the clamp on the rotor, and according to Wilwood, offer enhanced brake capacity and pad performance of the six-piston calipers, providing an intermediate level alternative to the bigger six-piston kits. Wilwood offers a full range of caliper finishes and rotor designs to enable the builder to personalize the style and optimize the brake performance for each individual application.
The assembly process is easy. The only difficult part is the safety wiring aspect. To properly safety wire a series of bolts, a set of safety wiring pliers is necessary. A good torque wrench is also useful because many of the bolts on the assembly must be torqued to spec. Other than that, it simply takes a little knowledge and grease…lots of grease.
Follow along as Jim Sleeper assembles the Wilwood DynaPro 6 disc brakes the right way.
Wilwood DynaPro 6 disc brakes are some of the finest on the market. They are made from high quality components and are designed for competition use.
Made from billet aluminum, the hub is a work of art. The outer flange section has multiple holes, allowing it to be used on a wide variety of vehicles.
High temp/strength thread lock is used on the threads of the wheel studs.
One trick when torquing the studs is to use the wheel itself to hold the hub. This not only ensures that the studs are in the right holes and fits the wheel, it keeps the hub steady during the process.
The bearings are liberally greased using high temp grease.
More grease is applied to the hub.
A flat punch is used to set the seal in place.
High heat-resistant thread lock is applied to the threads of the bolts that will affix the rotor adaptor to the hub.
The rotor adaptor bolts are tightened using a pneumatic gun. They will be torqued to 55 ft-lbs. Note that the Wilwood rotors are directional, and must be positioned correctly for them to work correctly.
