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 pas-
sages 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 cali-
pers 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, rear, left or right position. Use 7812 type pads.

Superlite Thearmlock T1 Caliper Pistons
Thermlock technology, widely used in NASCAR competition, is now offered on the Superlite Caliper Piston. Multi-piece piston
manages heat to reduce thermal transfer under the most severe racing conditions. Use as a service replacement or an upgrade
for stainless steel equipped or older calipers.
