Brake Options for 1968-79 Chevy Nova and Pontiac Ventura
The 1968-79 Nova and Ventura range splits naturally around what happens at the spindle. Keep it, replace it, lower it, or use it as the foundation for a larger brake package, and each choice sends the front end in a different direction.
For 1968-74 cars, the original spindle can remain in place with an OEM-style disc conversion. Changing to a 2-inch drop spindle adds stance to the project, while 13-inch systems step beyond both approaches with C4 Corvette-style rotors, aluminum hubs, and dual-piston calipers. The 1975-79 cars then branch into their own drop-spindle and 13-inch configurations rather than sharing the earlier hardware.
The rear of the car is less tied to that front-end decision. GM 10- and 12-bolt or Ford 9-inch rear ends can lead to separate 11- and 12-inch disc systems, including BlackOut and Wilwood parking-brake configurations.
Complete four-wheel packages bring those otherwise independent choices together, with stock-height and lowered versions available for earlier X-body applications. This makes the collection unusual because front ride height, front brake size, and rear axle type can each be changed independently before coming together in one complete braking system.
FAQ
How do I choose brake parts for my 1968-79 Chevy Nova or Pontiac Ventura?
Start with the exact year because the collection includes different conversion systems for 1968-74 and 1975-79 applications. Then check the existing spindles, front and rear brakes, rear axle, wheel size, master cylinder, and manual or power assist. If the car has already been modified, select components around what is currently installed rather than relying only on original specifications.
Can I convert a 1968-74 Nova to front disc brakes without changing the ride height?
Yes. POL offers a 1968-74 front disc conversion designed for OEM spindles. A complete front-and-rear power disc package is also available that retains the original stock ride height. Separate stock-height disc brake spindles provide another option when the existing spindle arrangement also needs attention.
What is the difference between stock-height and 2-inch drop-spindle brake conversions?
A stock-height setup allows the brakes to be changed without using the spindle to lower the front of the car. The 2-inch drop-spindle systems combine the brake conversion with a lower front stance. POL offers standard and BlackOut drop-spindle configurations for 1968-74 cars, while later 1975-79 Novas have their own drop-spindle conversion.
Are 13-inch big brake kits available for these Novas?
Yes. POL offers a 13-inch system for 1968-74 GM X-body cars using C4 Corvette-style rotors and dual-piston aluminum calipers. A separate 13-inch conversion with 2-inch drop spindles is listed for 1975-79 Novas. Larger brake packages require careful wheel-clearance checks before ordering.
Can I convert my 1968-74 Nova to four-wheel power disc brakes?
Yes. Complete front-and-rear power disc packages are available in both stock-height and 2-inch drop-spindle configurations. POL also offers different booster sizes and options such as drilled and slotted rotors, powder-coated calipers, and stainless hoses on selected systems.
Which rear disc brake kit should I choose for my Nova or Ventura?
Choose according to the rear axle actually installed. POL carries rear conversions for compatible GM 10- and 12-bolt rear ends and Ford 9-inch configurations, including 11-inch, 12-inch, BlackOut, and Wilwood options. Confirm the axle housing, flange and bearing configuration, offset, bolt pattern, parking-brake requirements, and wheel clearance before selecting a kit.
Will these disc brake conversions work with my existing wheels?
Wheel requirements vary by conversion. POL states that its 1968-74 OEM-spindle system works with 15-inch and some 14-inch wheels, while the 2-inch drop-spindle system works with 15-inch and most 14-inch wheels. Larger 13-inch brake packages need considerably more clearance. Always check wheel diameter, offset, spoke profile, and inner-barrel clearance against the exact kit rather than wheel diameter alone.
