Hello there,
I was going through the last summit catalog and I found wilwood was making these dynalite calipers for about 125$ each which is the price for rebuilt ones but these ones are brand new forged ones!
Did anyone adapted these on a disc brake spindle? I have to change my calipers but I'd like to buy something new, I'm a bit worried about the quality of a rebuilt caliper...
The distance between the two mounting holes is said to be 5'25". Does anyone know how much is there between stock 4pistons Mopar calipers?
Thanks for your help

Marc

And by the way, if I have to resolve to go the reman way, what's the best, Raybestos or A1-Cardone. Does anyone has some feedback to give?
Thanks again

Marc

I believe this is what you are looking for:

If you want to add the Wilwood calipers, try this:

Here's a link on the Wilwood conversion:

Keep in mind that Wilwood calipers do not have external seals. They are not really made for all weather or the dirt of full time street use. If they are put in the real street environment they will need extra service to keep them safe. It really depends on how you use your car, they may be perfect for you.

If you go the rebuilt route I would try the Raybestos parts before the A-1 Cardone. Another option would be to order new Raybestos pistons and kits from Rockauto and do it yourself. Your pistons might be fine but new are not expensive and it is easier and more of a sure thing. I bought rebuilts locally but ended up tearing them down and putting new kits in them anyway so I could put a nice finish on them.

We make the Wilwood adapter kit that hanges the Dynalite calipers directly on a Mopar disc brake knuckle. I have kits for the big 11.75 rotors as well as a kit that hangs the radial mount caliper on an 11 inch rotor.

These are really drag race type kits but some people have had success with the Wilwood calipers on lighter cars. (A body with slant six would probably be okay to run Wilwood calipers)

The Wilwood calipers save about 20 lbs of unsprung weight so it is a worthwhile swap for some applications. Wilwood isn't a super high quality vendor though so I don't like to sell these things for a daily driver. Their ideal use is on a drag race car.

I have used these calipers with Andy's kits on my 64 Dart (street and road course) and my 66 Valiant (road course). They are light cars, but these work very well and are extremely light... Thanks again Andy!!!

Hi Lou, long time no see.

You're the one guy who I know has had good success with the WW calipers on a non-drag race car. I think that car weight has a lot to do with it but I also suspect that you're a good driver and a good mechanic.

I have another customer who road races a Valiant with a V8 engine and his car was fast enough to shred the WW pads after just a dozen laps. That was at PIR which is a pretty fast track though.

In any case, for road racing I always recommend that people step on up to the 17 inch rims and use 13 inch rotors. Here is a shot of the brakes on a '65 B body that I did for a customer.

I think I probably am pretty easy on brakes. I have ridden with several people who ride their brakes way too long, IMHO. My pads, on either car, last around 3-4 track weekends or 2-3 track weekends and 5-10k miles. Super easy to change out.

The Valiant weights 2720 with me in it and a full tank with rollcage, and the Dart is about 2950 in street trim (no cage, w/me and gas).

Thanks again for all the help and hope all is going well for you.

Lou

All right, I guess I'll go the rebuilt way cause' I don't want to bother with some reliability issues (especially on the brakes, right?) on the sealless wilwoods...
Why did you tear them down? They are given new seals and pistons I assume (otherwise what's the point of a rebuild!!?)?

Thank you all for your help and Happy New Year!

I bought a local brand of rebuilt calipers, not Raybestos. I put a baked on finish on them called Gunkote, so I needed to tear them down for the process. The seals were imports, so I was happy to put in Raybestos kits which only cost a few dollars each.
