Delco J56 Twin Pin Caliper Assemblies with Titanium Pistons
These are stainless steel sleeved Delco J56 Calipers. The twin pin design keeps the pad from moving around in the caliper housing, and is a good idea, particularly in the front. An additional benefit is the ninety degree bend in the top of the backing plate which adds stiffness to the pad. Our calipers use the tried and true GM lip seal pistons with titanium insulators. They come with either our Gold or our super premium Platinum racing pads. Select Front or Rear. Free Freight

Duntov Big Bore Front Caliper Assemblies

The Duntov Big Bore front calipers are standard Delco single pin Corvette castings that we bore and stainless steel sleeve to 2.0625 inch bore diameter, resulting in 21% greater clamping power. We then install a spacer under tension that acts as a bridge to reinforce the caliper across the center of the pad area. The pistons, lip seals and boots are GM, and the titanium insulators are our own. The pads are special for these calipers, as they are clearanced for the bridge spacer. Free Freight

Duntov Big Bore Wide Front Caliper Assemblies

These are Duntov Big Bore calipers that are spaced out to accommodate thicker pads. The pads are .800 thick vs. the stock .525. The purpose of the thicker pads is heat insulation. Brake pad material is a great insulator, and when combined with our RB164 titanium piston insulators and 5-inch air duct, brake fluid temperature is greatly reduced. The additional thickness is not available for use without using our titanium spacers. The stroke of the caliper pistons determines the amount of pad material you can safely wear away. After we use the normal amount of wear off our .800 pads, we surface them and rotate them to the rear for use in our RB120 Rear Bridge Calipers. Free Freight

Rear Bridge Caliper Assemblies

These calipers have the same bridge bolt and use the same pads as the RB118 Duntov Big Bore Front Caliper Assemblies. They are also perfect for using up the remains of the thick pads from the RB119 calipers once they have been worn down to the stock thickness and resurfaced. Free Freight

Backward Front Caliper Mounts with Air Ducts

Mounting the front calipers behind the spindle is a very good idea. The primary benefit is that it allows a 5 inch air duct to direct unobstructed air into the center of the rotor. Also, the new caliper position equalizes bearing loads, and the weight of the caliper is moved rearward. Free Freight

Please specify standard width calipers or Duntov Wide calipers.

Stock Type Vented Steel Rotors

It is easy to find vented stock rotors, but they are for street cars and they are all plated to prevent rust developing in the grooves. The plating destroyed the rotor for racing use. We cut these vents ourselves and they are ready to install in your racecar. Freight Free

Single Pin Std Thickness Racing Brake Pads

Our Gold racing brake pads were chosen after a lot of testing. We evaluated bedding, cold pad performance, friction coefficient, feel and longevity. We have used these pads for several years, both front and rear, and until we found (and could afford) the Platinum pads, these were the very best. Now we run the Platinum pads. They are obviously more expensive, but they generate much more stopping power. With greater stopping power, more heat is generated.Check out this article before switching to the Platinum Pads.

Duntov Bridge Caliper Thick Racing Pads

These .800 thick pads are designed to work in the RB119 Duntov Big Bore Front Calipers and when worn down to the thickness of the standard pads, can be resurfaced and used in the RB120 Duntov Rear Bridge Calipers.

RB172 Duntov big bore thick racing pads
Caution: On the .800 pads, once wear nears the DO NOT EXCEED LINE, the pads must either be replaced or shimmed using our Part # RB074 titanium spacers. Use beyond the wear limit without adequate shims can result in a piston seal clearing the caliper bore, causing loss of brake fluid and total front brake failure! Stay on top of pad wear and make sure the total pad thickness and spacer thickness is always greater than 360 thousandths.

Duntov Titanium Thick Pad Wear Spacers

These titanium spacers serve two purposes: They are great insulators, and they allow the use of the pad material on the thick pads beyond the DO NOT EXCEED line. The spacers are .125 thick, so to use the extra pad material in the Duntov .800 pads you will need 1 spacer per side, or 4 spacers for the car set. DO NOT ATTEMPT TO RUN THE PADS BEYOND THE DO NOT EXCEED LINE WITHOUT THE SPACERS!

Titanium Racing Piston Assemblies

If you already have your calipers and just want to change to our pistons, you will want these second design improved titanium insulators. We designed them for the road racer who has had enough of brake fade caused by boiling brake fluid. They are expensive, but so is going off the track and hitting a tree. Included are an axle set of seals, dust boots and O rings.
