Have a box of Wilwood brake calipers in my garage I forgot I had. 6 calipers in total not sure if they're all have a match, I think at least 2 set are a pair maybe all 3 sets. They're pretty light and seem to missing parts here and there.
First one: JT-120-6816
Second one: BE-120-1053
Third: AD-120-1053
Fourth: ??-120-1053
The smaller ones:
AE-120-1055
DE-120-1051
Anyone familiar with these part numbers?
Your part numbers are coming up in google if you drop the letters and just use the hyphenated numbers
In reply to Patrick :
Oh snaps. Thanks!
Wilwoods website is great about part numbers (at least current ones) and often has drawings with dimensions and the formulas to design caliper carriers based on rotor size.
Been doing a lot with the tiny dynalites lately
Common run of the mil dynalite calipers used on just about every brake kit. The ones with the larger 1.75" pistons are for front kits. They all look like they have the GM 5.25 mount spacing. The ones with the external crossover tubes are at least 10 years old. The ones you buy now have internal passageways. The part number will differentiate the Dynalite in three ways; mount spacing, piston diameter, and rotor thickness. The halves are the same no matter what the rotor thickness is, there are just different spacers in between the halves.

Thanks!
Some of them are missing a tab at the bottom (you can see in the pics). Does that render them useless or what?
The Pads have a Pin Holding them in Place, the center hole up top. the tabs keep them from Falling down to the Hub When Changing them when they are red Hot during a Race. Still Good Stuff, Aka 4 piston Caliper.
I wouldn't use them with a missing tab, but they would probably be OK. Brand new ones are $134 a piece from Summit racing delivered for free to your door. Thats almost throw away money when your talking about really good brakes. If you have one good one and need a mate, keep an eye on ebay for a match. Used Wilwood stuff comes up cheap all the time. Just search Wilwood and narrow the search down to used parts. I probably have 3 sets of new Dynalite and Dynapro calipers in various sizes and at least that many used sets sitting in the garage now. I'd be willing to bet there are a bunch of guys here that have similar collections. Racers tend to go thru brake calipers like they are consumables. Not worth the hassle of rebuilding them when they cost about half the price of one Hoosier race tire. Its a perspective thing.
