Viper Caliper kit
The Feb 03 edition of Mopar Action had an article on the Green Brick, the AR Engineering kit to convert older Mopars to Viper Calipers and brakes was included. Tried to contact Hershberger on the net to get some prices, no answer on the E-mail. Anyone have any idea on the cost of the entire kit or can it be purchased in seperate parts?

well the racing brake pads in the mopar book run about 330.00 for the front oh.. wait.. the rear are cheaper 295.00... I think the whole thing may be quite costly ... but I cant say for sure.. comparing to the pads though... may be less expensive pads but it dont list them..

George,
The Viper conversion kit is $175 suggested retail. Then you'll need a set of hoses which is about $100 with adapters. You'll also need '73 to '76 A body drum brake knuckles ($50 swap meet parts) and of course the 11.75 rotors + bearings, seals, etc. The expensive part is the calipers at $500 each new. But, Viper guys sell used calipers all the time for about $300 a pair. Log onto a Viper web page and check out the for sale ads. I'm not sure if the Hershberger guys do a lot of e-mail volume. Call them, 1-800-311-3945. Ask for Ken or Chris in the parts department. Any other questions just log onto our website at www.ARengineering.com and read the Viper kit instructions. Andy F. |

I'll put this back to the top in case George hasn't seen it yet. I talked to the guys at Hershberger today and they have Viper kits in stock.

AndyF, I'm a bit confused. You say here to use the drum brake spindles, but the original unicast rotor conversion uses the disc brake spindles. What is the difference? Does this mean that '73-'74 E body spindles won't work with this swap?

The caliper mounting bracket that holds the Viper caliper needs the square bolt pattern available on the drum brake knuckle. The 11.75 unicast rotor fits on the drum brake knuckle just fine.
So no, E body disc brake knuckles will not work. You need to swap to the '73 to '76 A body drum brake knuckle in order to bolt this kit on. |

viper calipers
Hey out there!
I just e-mailed an inquiry to a junk yard which seems to have a few wrecked vipers to part out. Will let you know if this source pans out. Since Dr. E's brick brake conversion article, I have seen a great deal of interest from others in doing this conversion. What about a group buy for viper/brembo calipers? I'd like a new set for my '65 dart (which, incidentally just got painted!) KenAbody |

Have you though about going to AR Engineering and using the adapters for the wilwood calipers. They come in many sizes and are real race units and are much much cheaper and pads are everywhere and cheaper too. Good enough to slow an 800 hp 3500 lb Nascar racer on the road courses, so I bet it will stop yours and a whole lot cheaper than the Viper conversion. |

I have the 11+ on the car now with sliders and feel the stopping power should be eqyal to the Wildwoods. AndyF, EBooger from Mopar action and others are not comfortable with the Wildwoods for a regular driven car and my 74 Duster is a daily driver. The 74 is also my toy which will never be finished, I have all of the parts except the calipers to do the conversion.

Fair enough.
I dont see why they would not last though. Any reason you know of. I use them on race cars and they hold up fine, so far. |

Really dont know why they would not work except the wear factor is something like a pair of pads in approx 7,000 miles or less. And I trust E-Bergs opinion he usually deliver the facts from personal experience or states it is an opinion, the only other mag writer who doe's this is??????????

some of you guys keep saying "knuckle" while others say "spindle". Which is the part that is most critical to this conversion as I have a complete set of '74 "A" body drum brake assy's with control arms laying around.....

I think what E-berg had trouble with on the Willwoods was the lack of weather seals on the pistons bores, so they could potentially get all gunked up in street duty. He later kind of took that back and also commented that under HARD use, the weather seals on the stock calipers can catch on fire from the heat generated. So, use whatever you want, I say. If I stumble across a good deal on a pair of appropriately sized Willwoods, I'm not going to pass them up. I'd rather have the Viper calipers 'casue they're just neater, but to each his/her own.
I think here the terms spindle and knuckle are being used interchangable, since it's just one forged piece. I think "upright" has also been used, but as long as you're talking about the piece where the brake rotor or drum bolts on, you're talking about the right part. Clair |

The Wilwood kit was designed for drag racing. It uses a very lightweight caliper that has fairly thin pads. They'll wear out quickly on the street and they won't stand up to the abuse that a fast, heavy car can dish out.
I do have at least one customer who road races with the Wilwood conversion kit but he is running a lightweight A body with a /6. It is a nice little car and the brakes work fine on it. Anything heavier and you should really use the Viper caliper. We recommend the Viper caliper for any street driven application since they are fully DOT approved, have weather seals, use the superior banjo bolt connector, have bigger pads and the pads are an over the counter item. The Viper calipers are made by Brembo. Brembo's products are far superior to anything that Wilwood makes, but of course, the price reflects that doesn't it! This info is all on the webpage at www.ARengineering.com if you're interested. We try pretty hard to help people make the right choice, but some people just aren't interested in listening. |

Question for AndyF, I have a set of Mopar braided hose P5249274, can these hoses be used on the Viper brake conversion?

Viper calipers
I have just received a matched set of Viper calipers from an outfit in Florida. The price that I paid is between me and the seller, but I will say that the items are like new (one caliper even came loaded!). This rates as one of the best bargains I ever made. Here is the e-mail address:

Another question for AndyF... are the drum-brake spindles "handed", as in, is there only one part, or do they have to be DS/PS? I'm asking because I tried to snag the only pair of spindles out in the salvage yard a couple weekends ago, and the DS spindle was WASTED. The inner bearing surface was worn down past the chamfer! PS was good, so I snagged it in hopes of finding another one some day. If they're the same side-to-side, I'll have a little more flexibility out in the 'yard.
Thanks, Clair |
