Billet Dynalite Single Calipers
Black anodized aluminum single piston caliper is ideal for open wheel racing. With 3.25" lug spacing, it weighs just 1.4 lbs. and secures a .58" thick, 1.1" cubic inch brake pad with Quick-E-Clip pad retainers. Internal fluid passages and multiple bleed fittings permit right or left, front or rear mounting. Will fit .250" to .380" thick rotors with diameters from 6.00" to 13.00". High-temperature square piston seals control retraction and stainless steel deep-cup pistons reduce heat transfer from pad to brake fluid. Calipers accept 1/8"-27 NPT inlet fittings and use 6812 type pads.

Forged Billet DynaPro Lug-Mount Calipers
Designed for applications that previously used Dynalite model brake calipers. DynaPro 5-1/4" mounting calipers are stress-flow forged for exceptional strength and include a wide array of improvements. Calipers feature Quick-E-Clip pad retainers, which eliminate the need for caliper removal when replacing pads, while the heavy-wall stainless steel pistons slow heat transfer and resist corrosion. Internal fluid passages and four corner bleed screws allow mounting in front or rear, left or right position. Use 7812 type pads.
