Designed Specifically For Drag Racing

Evolution Rear Brake Kit
For OEM Large GM 12 Bolt Housing Ends

Requires
• Strange axles with A1031 or A1031Z Eliminator Kit
• 2.832″ brake offset

Evolution S Dynamic Drive Mount (DDM) Stainless Steel Rotors – B2798L / B2798R
• Evolution S Rotor mounts to Billet Aluminum DDM Hat – reducing rotating weight
• DDM system secures the rotor and allows for rotor thermal expansion – drastically reducing warping, coning, and cracking which are common with bolt retention designs
• DDM system design is secured by an internal Spirolox, eliminating heavy bolts and hardware- further reducing rotating weight
• Evolution S rotors are machined and fully ground from Stainless Steel that exhibits 48% greater yield strength at 1,000° F compared to carbon steel- further maintaining rotor integrity
• Stainless steel Evolution S rotors are highly resistant to heat and corrosion
• Unique Aero Slot design reduces rotating weight and promotes even heat dissipation- compared to common round drilled holes
• Scalloped design further reduces rotating weight
• 11.250″ OD / .355″ thickness

Four Piston Billet Evolution 4 Calipers – B1900
• Stainless steel pistons mitigate heat transfer to brake fluid
• Reverse dish pressure vessel piston maximizes stiffness
• High retraction piston and O-ring design to eliminate drag during acceleration
• Computer finite element analysis (FEA) optimized and field-tested calipers- Evolution 4 design improves piston retraction, pedal feel, and stiffness resulting in improved pad wear and exemplary braking efficiency
• All pistons are 1.750″ for increased clamping force

DTC-30 Semi Metallic Brake Pads – B5010
• Provides the best starting-line cold holding power
• Recommended for vehicles going 150 MPH or less in the 1/4 mile

Aluminum Caliper Mounts
• Billet one piece design
• Eliminates bolts, spacers & nuts that require periodic maintenance

Inner C-clip Eliminator Halves
• Modified halves fits both A1031 / A1031Z kits
• Maintains same wheel to wheel width as drum brakes
• No pressing required provides easy installation
• New oil seals installed in halves

Low Profile Caliper Option – OPRB12

Brake Hoses and Lines Are Not Included
Calipers are tapped 1/8″ NPT and supplied with a straight male 3 AN fitting

Use Teflon® tape or liquid on the pipe threads of the fitting
Leave a few threads from the tip uncoated
This will avoid depositing material inside the caliper
Torque fitting to 25 ft lbs
