What's in the Box

Wilwood Dynalite rear brake kits combine high performance braking, high-tech style, and functional simplicity for rear axle disc brake conversions that require a parking brake. Whether its a simple conversion from drum brakes, or an upgrade to compliment wheels, tires or suspension equipment, these kits have it all.  

The emergency brake functions as a drum brake hidden within the mounting hat of the rotor for a clean installation. E-brake cables sold separately. Caliper has a 1/8" npt inlet.

  • Big 12.19" x .810" one-piece vented rotors
  • Rotors drilled to accept 5 on 4-1/2", 5 on 4-3/4" and 5 on 5" bolt patterns
  • Forged billet four-piston calipers
  • BP-10 Smart pads for a quick response and fade resistance
  • Aluminum mounting brackets
  • Includes all hardware

Nice Brake kit, I needed to do some mach

May 08, 2013
Bought this brake kit with emergency brake because an emergency brake is always a good thing. And because Pennsylvania requires it in a street rod. My 9inch ford has a 2 1/2" offset and, I double checked it.... Put it all together all went easy and smooth. Last piece i tried installing was the caliper. And it rubs the outside of rotor. There is a spacer under the caliper bracket held on by 3 bolts. I removed it and had 1/8" shaved off of it. Then with using the spacers provided with the kit i got the caliper lined up where it should be. Rotor right in the center. Thanks Speedway and Wilwood Disc Brakes.
Pros:
  • Easy To Install
Cons:
  • needed to machine a spacer
Yes, I recommend this product.
