CB's rear disc brake!

[marco the steem engine]

dose anybody know what car, the calapers are from? so I can get some new, softer compound pad's!????????

[Derrick from NC]

I haven't seen their latest kit but I know at one time they used a single piston caliper with parking brake mechnanism from the H20 VWs....Golf?

[ray greenwood]

From what they told me it is a GM design single piston sliding caliper. The rotors are 914? If so I'm thinking of the right system. Ray

thats them ray (a GM design single piston sliding caliper), but what production car uses them calipers??????

[jrg_mm]

I alson want to know what type of calipers they are becaus I want to use the baer system calipers, 4 piston, or if anyone know if there is a kit out there for front disk brake system for a 71 superbeetle with 2 or 4 piston calipers...

For those who drive 411/412...I have found that the CB rear braking system will bolt right up with a few minor changes. The inner rear bearing must be swapped for a ball bearing from type 1...same outer race diameter! A pair of type one stub axles on the inside...or possibly a pair of type one length stub axles with stock type four size bearing from transform will fit. Also a new inner bearing spacer will have to shimmed up. But thats pretty much it. The outer bearing cover on type four trailing wishbones are the same as a bug, just a different seal diameter. Not sure if I'm going to install the inner bearing retainer circlip, or use a through bolt design like stock type 4 yet. I hope to have them on in a couple of months. It will allow use of stock type one rear hub either four or five bolt. On the CB kit these bolt up to standard 914 rear rotors. I alreay have a set cross drilled. I'll let you know how it works...and post some pictures. Ray

I just added a cb 4 wheel system to the test car, with 5 lug Porsche patterns.

My rear calipers are from A Subaru....

marco, if the calipers are what i think they are, they come from late 80's early 90's "w" bodies( lumina,grand prix,cutlas,regal). on the gm cars they had a problem with slide pins siezing from rust, but maybe cb cured this problem.

and when those sliding pins sieze it takes some serious force to get em out. i just did the brake pads on my s-10 today and the sliding pins were siezed and it took a 1/2"rachet with the hex bit and a piece of pipe to extend the handle to break em loose.

its also tricky to get the GM calipers back in without the pads falling out(no retainer clips)

[marco the steem engine]

yep thats the one's , the pin's were rusted solid after a year on the car!

(they come from late 80's early 90's "w" bodies( lumina,grand prix,cutlas,regal). on the gm cars they had a problem with slide pins siezing from rust, but maybe cb cured this problem.)NO!

what car are they! I'm from the UK and havent herd of one of them cars!
I'm looking for some softer pad's dose anybody know?????

[briansbug]

your dead on ray! (i work on gm junk for a livin') marco, i don't think they ever sent any of these cars across the "pond" but maybe if you can find an american pad dealer(wagner,raybestos,bendix)they might have access to these pads over there.

The problem with the GM caliper pins was not the pins, it was GM's choice of lubricant and the use of cad plating. They did not use an actual anti-sieze lubricant. They used a high temp grease. Cad plating is wonderful stuff for hardware. Looks great! Cad plating is also prone to attack from any chemical with a high PH (caustic). A lot of wheel cleaners are caustic. Once the cad begins to pit, even the relatively moderate PH of road salt will cause accelerated corrosion. Couple this with steel, cad plating and cast-iron...all in contact, and you have galvanic action. All probably due to a poor choice of lubricant. These reasons are one of the many of why I tend to not like to work on GM equipment unless it is driven by someone attractive (and female) hee hee Ray

[ray greenwood]

Wagner and raybestos...and probably others have very extensive "picture" catalogs at some parts stores. I know it doesn't help for actual dimensions, but they usually have the years and make of what they go on. Napa usually has this also. Maybe if you have the pad, you can match it up there. The pins on thes calipers will have less trouble, if you go ahead and remove the cad plating altogether. Just do not leave deep scratches in them. Lube them with anti sieze. Felpro C5A (available at fel-pro dealers and Grainger supply) has a very low oil/grease content and a 1600+ degree temp range. Its mostly copper and silica. You will have to wipe it off and add some more about once a year, as it oxidizes to black and becomes less useful. It will not hurt the rubber seals.

Marco, I know its sounds awful but get down to your local halfords and they should be able to match it with their books as they have "to scale" pictures of zillions of pads, then when its matched get the car model of the staff member and run out the door!
This has worked for me before so you should get a result.
