D52 Caliper Rear Disc Brake Brackets

[lolife99]

Look at Speedway Motors for brake hoses. They have both rubber and steel braided.
The Wilwood D52's take a 7/16-20 banjo bolt to secure the hose.
Some of the OEM C10 d52's take a 7/16-20 or a 10mm metric banjo bolt.

Does the 12 bolt rearend width (in a 72) stay the same with this kit installed?

[Captainfab]

No. the width increases aproximately 1/2", depending on the particular rotors you buy. If you can find a good useable set of original rotors, they had the thinner stamped steel hat. I haven't found that style available from the aftermarket, but you may be able to. So those wouldn't increase your width any.

Any reason to worry about the lug stud length being too short?
Also 1/2" total width,... or per side?

[Captainfab]

I haven't checked to see if it would be a concern or not.....I probably should do that. Yeah that 1/2" is total, ~1/4" per side.

Ok ... does Wilwood make a D52 replacement w/ E brake ?

[Captainfab]

I haven't seen any on their website. Their rear disc brake kits appear to use the internal shoes for the e-brake like GM does on later model vehicles.

Are you still making these brackets? They look way sturdier than the junk on eBay.

[Captainfab]

Yes, I make all of my products everyday including these D52 brackets. Send me a PM for ordering/payment info.

Alright. Income tax hit. What do I need to do to get a set ordered from you? I’m not worried about powder coating. They will be painted.

Hey I would like to buy a set of your lever,cable bracket and spring kit for my 1976 Cadillac rear disc calipers. I purchased a set and they are bare.

Let me know if you have some in stock and how much then I will send paypal.

Thanks!

I came across this nice proportioning valve today that might be of interest to you guys doing the 4 wheel disc conversions. It has a built in adjustment knob. They are a good price also. About 1/2 the price of an aftermarket fixed proportioning valve.

It is available from Jegs as well if you prefer doing business with them instead.

Wilwood shows four different calipers on their web page. Two for the 1" rotors and two for the 1.25" rotors. The difference between them is piston area. Any one know the in's and out's of choosing the correct one? I would think the larger piston area would equal more pressure applied to the rotor. But I'm no expert.

[lolife99]

Larger piston is for the front.
Smaller piston is for the rear.

[toms84ss]

Cool, thanks.

There have been inquiries as to what the overall cost is for a rear disc conversion using my brackets. So I have put together a listing of the associated conversion costs for all 3 of the rear disc brake conversion brackets that I sell. Most of these prices I found online on Schucks/O'reilly's website. So anyone should be able to buy these parts for these prices.

• Brackets $242.00
• Rotors $67.98
• Calipers $71.98 (includes core charges)
• Pads $22.99 (semi-metalic)

• Banjo bolts $6.58
• Total $438.51 (with front calipers, no e-brake)

Some additional figures to use for comparison purposes. Larger diameter piston means more pressure applied to the pads.

Captain
will your d52 brackets,wilwood d52 calipers & '94/'96 Impala SS rotors work?
Mac

[Captainfab]

No, you cannot use the Impala SS rotors with these brackets and the D52 calipers. These are designed to be used with the Astro van rotors which are much thicker than the Impala rotors, and will be the same size as your front rotors. Why do you want to use the Impala SS rotors when they are lighter duty and more expensive than the Astro van rotors?

Allready purchased front & rear crossdrilled rotors w/ wilwoods in the front.Had the impala calipers planned for the rear but would much rather use the wilwoods in the rear also.I know the astro rotors are thicker where the pads ride but How thk. are they at the axle compared to the impala ones,I dont have any more back space left w/ the wheels i'm using. Do you know if we can get them cross drilled & zinc plated?

CaptainFab, have you seen anyone combine your brake conversion kit
with an underdash pedal kit?

Like from Scott's Hotrods? (http://www.scottshotrods.com/UnderDashPedalAssembly.asp)

[Captainfab]

Not to my knowledge.......It wouldn't function any different than having the booster and master on the engine side of the firewall, as long as you have the correct components for a disc/disc system.
