D52 Caliper Rear Disc Brake Brackets - Page 8 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

CSoliz · 08-21-2012, 10:39 PM

Captainfab,
I'm gathering parts for this conversion and I am curious what master cylinder too use. Is there an easy way to find an MC that is disc disc that will work on my 78? It looks like I have a 1.125 bore.

Thanks.

CSoliz · 08-22-2012, 09:43 PM

I believe I got it. I think I am going with this one.

One of the most common master cylinders to use for a disc/disc conversion is a Corvette master cylinder. You will also need either a disc/disc proportioning valve or an adjustable valve in the rear line.

I cant find a pic of how those emergency brake 1976 Cadillac Eldorado style brackets,levers and springs bolt up to the calipers? Do you have some good pics of how they bolt togther? I cant find any online.

**Captainfab** · 03-22-2020, 09:47 PM

Pictures and some discussion are on pages 12 and 15 of this for sale thread.

It seems your bracket and spring kit does not work for 1976-1978 Cadillac Eldorado calipers as that is what I have. I have those because I was told that that the later 79-85 calipers will not bolt up to your caliper brackets as they are a different bolt pattern or else I would have purchased the 79-85 calipers.

My calipers are like the ones posted by Twisted78ss posted on page 15 as his right caliper does not have a bolt hole in order to attach the lower e-brake bracket and neither of my calipers have that hole either.

I will try to figure out how to post a pic of my calipers although I dont see how that will help now that I have seen what was posted on pages 12 and 15 and the lack of bolt holes to attach that bracket.

I would like your input on this as to what needs to happen so I can move forward.

Just be sure it matches your piston- shallow or deep- and you should be good to go. Stock disc/drum combo valve can be gutted for use with disc/disc...

Cool. I was going to pick up the prop valve you have suggested. Thanks for all the help Capt. I will be ordering real soon, probably within the next week.

gringoloco · 08-27-2012, 03:59 PM

Received my brackets the other day--they look great! Well packaged and BEEFY. Gonna look great in satin black powder.

Thanks again!

Also, if anyone is looking for a set of rotors for this swap, I have some for sale cheap here:

Hey Capt, Would it be possible to use a line-loc unit as a parking brake with the either caliper? I would think you could, any thoughts..

**Captainfab** · 09-13-2012, 11:08 PM

Using a line lock or a Mico lock has been done many times. It does work but it is not legal in those states that require an e-brake. It has to be a mechanical e-brake to be legal.

How about a complete drum to disc conversion kit for my 72 c10 rears? Got em? Price? Thanks

**Captainfab** · 10-11-2012, 12:17 AM

I have never sold a complete conversion, just the brackets. It just seems pointless to be to pay the shipping on the rotors and calipers, etc. which are heavy, when you can just take the parts list down to your local auto parts store and pick them up.

**Captainfab** · 11-23-2012, 12:35 AM

Yes, these will fit all truck 12 bolts from '64-'82 and the truck 10 bolts from '80-'87

Do you make plates for a 63 c10 5 lug conversion?

**Captainfab** · 11-28-2012, 11:44 PM

Any of my 3, 5 lug rear disc brake brackets will work with the 5 lug conversions on the original 6 lug differentials. However if your '63 has the original 12 bolt, they will not work for you. This is because the '63 12 bolts have pressed on backing plates. Therefore there is not a flange welded to the axle tube that the backing plate bolts to. The best option for disc brakes on a '63 12 bolt will be a weld on caliper bracket.

just out of curiosity i dont know anything about the cadillacs but if the rear calipers work would the rotors not work as well since they should be the same thickness as the astro rotors or would there be a back space issue since its a car? what about the master cylinder as well since it should be a disc/disc setup

sorry not trying to pick your brain just trying to see if theres more options
