After a year of design, prototyping, and development, a new upgrade to the venerable Delco brake caliper is about to be released. The new pistons and seals are designed to stay in the car for a season of racing at ten-tenths. Even with the superior insulating qualities of Duntov’s titanium racing pistons, the current stock-type seals are generally good for only one race weekend. Changing out the seals involves removing, overhauling, reinstalling and bleeding a car-set of calipers, which typically takes eight man-hours. The new Teflon seals are designed to last a lifetime of street driving, but Duntov is in the process of demonstrating continual use for six race-weekends, which would save forty man-hours of labor, and effectively remove one of the reliability issues Corvette racers have always had to contend with.

The internal friction generated by grease-packed conventional opposed tapered roller bearings is substantial. Duntov’s new bearings reduce this rolling resistance by an astonishing 40%. They are available now and we will have them on the website within thirty days.
