My whole braking system - thinking out loud

[Alvin]

This just in from the Wilwood website:

The D52 calipers made for a 1" thick rotor will work on rotors .81-1.04" thick and 11-12" in diameter.

The D52 calipers made for a 1.25" thick rotor will work on rotors 1.19-1.28" thick and 11-12" in diameter.

Seems you were on the right track all along CaptainFab!

[Captainfab]

Yes do, just let me know when you plan on being in town. No vacation this year, so I will be around most of the time.

This brake stuff can be a major PITA, huh? You guys are really do a great job with this though.

Hey CaptainFab, my Dad lives in Coeur d'Alene, Idaho. I'm going to be coming up there this summer to visit, so I may have to look you up and come bug you .

[Captainfab]

Thanks for posting this Alvin

I've been so busy with working on this new caliper bracket and my regular work that I haven't had time to search for that info.

i really hope u make these brackets work it would be awesome imma start saving my money now!

[smashingchuck]

Guess what came in today! Now to save some more cash for some rotors that don't rust...

[crakarjax]

You should update the first post with the outcome/summary of all this when you get it all installed, it would make a very good reference!

[silvereagle07]

I've just read this entire thread and I'm am very intrested in how this turns out. Here's a link to a company called R1 Concepts. I was thinking of using them on my Trailblazer SS. They are used alot on the TBSS forums. Check them out.

Astro all wheel drive rotors http://www.r1concepts.com/CHEVROLET/...sDetail.htm/NA

C10 front rotors 1.25 http://www.r1concepts.com/CHEVROLET/...esultsPage.htm

[Captainfab]

Oh I've already designed brackets that work. Now I'm just waiting on some costs so I can put this all together and have a final price for you guys. Should have that tomorrow evening.

Those look good Chuck. Did you get just the one pair?

So far, yes. Funds have been a little tight. Did you want to borrow one?

[staggerd86c-10]

I think i rather have the d52s up front and have a matching setup in the rear, captain fab is making the ideal kit for my application, Im going more for form then function, i think it would look almost stock on the truck. Please let me know when you have the fabbed up and ready to ship out i will send out the $$$ asap.

[Captainfab]

I'll send you a PM Chuck......

Unfortunately my supplier didn't get me the pricing today as hoped. He promissed me in the morning. I'll post up as soon as I know something.

[Captainfab]

OK, I've got the pricing on the caliper brackets for using the D52 calipers with the Astro rotors on the GM truck 10 and 12 bolt rears.

For the set of brackets with the mounting hardware will be $232.00 plus a flat rate shipping in the USA of $10.00. This consists of 3 pieces per side. The main reason for the cost is the 1.250" thick spacer needed between the brackets. This could have possibly been done with less cost, but the current design is what I feel is the best and safest way of accomplishing this. And I don't believe in cutting corners on something as critical as the brakes on your vehicle.

I don't want to clutter up Chucks thread with what could be considered a for sale add, so lets hear what you guys think of this price. Is it affordable, or do I need to look at a different rotor to try and get the cost down. The only other rotor besides the Lincoln and Impala would be one from a late 70's Eldorado. But they are only 11" in diameter and typically more expensive than the Astro rotors. If a few of you are still interested in these brackets, I will get some cut and post up some pics of the actual pieces you will be buying.

[lolife99]

I'm interested in the brackets.
Let me know when they are ready to ship.
Thanks for all the hard work.

[staggerd86c-10]

i'm interested also please let us know when you have the prototype setup so we can see what it will all look like. thanks for all the hard work in developing this for us.

The LS1 rotors are not as deep which could work if you redrilled the rotors... However I do not know the center register or inner diameter for the axle to mate up to.. i have no measurements...

[kvn1011]

Quick question captn, would the impala caliper bracket that u offer work with the d52? I was reading this website and they offer a d52 for replacements to the B body impalas
Link. http://www.impalassforum.com/vBullet....php?p=2260867

[kvn1011]

Would probably need. The caliper cage though

[Captainfab]

The LS1 rotors are 12.01" in diameter and 1.02" thich which while being bigger in diameter are thinner, which may not be an issue. The center register hole is 2.78" whereas the truck axles require a center register of aprox 3.08-3.10". So a machining process would be required. Then the bolt pattern is 5 x 4.65", so the 5 x 5" pattern would need to be drilled. The shallower depth would lend itself to a simpler less expensive caliper bracket, but I don't know if that would be enough to offset the cost of machining the rotors.

No, the Impala SS style caliper is completely different than the D52 style calipers. I didn't spend a lot of time reading on the Impala SS forum, but they were talking about front brake upgrades, not the rear. I used to make a bracket for the Lincoln rotors and the smaller GM Metric caliper. I have since sold out of that design, but I plan to develop a new improved desing in the not to distant future.

Well that's two of you guys still interested, so it looks like I'll be ordering at least two sets of brackets on Monday. Thanks for the continued interest.

[smashingchuck]

Um, obviously I would like a set too.

[suttoncurt]

Ok - i'm in captin fab - Let me know your ideas on running the brake lines to the calipers on the rear end . And you can send me a invoice thru paypal suttoncurt@yahoo.com

[suttoncurt]

Anyone know what years of astro van rotors will work ? I'm thinking as long as its the awd model it doesnt matter?

[Captainfab]

The rotor you will want is Raybestos #580442RGS That is the one I am using for mockup.

[Captainfab]

Yeah I assumed you would want a set Chuck.

Curt, I'll post up some pics of the final parts here before sending any invoices. That way you guys can see exactly what you'll be getting. Thanks for committing to a set.

So that makes 4 sets.....
