Another question 11,75 calipers

[WhiteOnGreen]

Hello to all, I am going to begin with my project and need your advice. I have used the Forum searcher and have been with great regarding post at the rate of the calipers for the discs of 11,75 but in all this I have many doubts.

My 68 Charger it had of original power drum brakes, but the previous owner installed a Wilwood kit disc brake 10,75 diameter rotor with manual brake, it is possible that this was adapted for drag but I notice a poor braking  :eek2:and with a lot of effort for street for it I would like installing the 11,75 rotors from Magnum or Cordoba

I have several options, to buy the spindles, discs and calipers of 78 Magnun, the powerbooster and master cylinder Bendix, but here the problem arises with the caliper bracket , it is very difficult to find, that's why I have looked and I found the Centric CE141.63019. what seems that it has the adapter of caliper but I have not seen any reference on them in the forum, Which you think?, it would be a good option or on the contrary there would be better another type of caliper as Bendix

I have a pair photos of the Centric caliper and some of my current setup.
Thanks guys

By looking at Centric's catalog, I'd guess that the part number you give for a 'semi-loaded caliper' means that it comes with brake pads installed but probably not with the caliper bracket.

I found my entire '79 Cordoba disc setup on http://www.junkyarddog.com/

It only took 1 day for a yard to get back with me, and I bought the entire spindle/caliper assemblies with lower control arms for $125.

I bought new rotors from http://www.google.com/url?sa=D&q=http://www.powerstop.com(Powerstop part number AR8309) because I hate cheap rotors. They're slotted and cryogenic treated, IIRC they cost about $300 with races installed.

They're not on the car yet, but should be getting assembled next week; I went with all stock Chrysler stuff just to avoid the hassle of finding parts that fit and work.

If you already have a complete wilwood set, maybe you should upgrade to wilwoods 12.19 rotor and bracket package rather than swap everything out for the heavier and harder to find 11.75 factory set up.

  Thanks for his answers, in the Centric catalog, Posi Quiet Calipers is loaded, according to his web:
 
"Posi Quiet Loaded Calipers
Posi Quiet loaded calipers are a full line of original equipment replacement brake calipers providing unmatched quality and value.

When installing Posi Quiet loaded calipers, technicians can be assured that they are getting top quality products that have been engineered to meet or exceed the function of the original part. Each component is specifically designed for each application and the attention to detail throughout the manufacturing and testing process ensures each caliper will perform to the exacting standards of today's vehicles.
Each Posi Quiet caliper is finished in the same way as the original from the factory; Posi Quiet calipers feature a Zinc Dichromate finish, or O.E. colored powder coating depending on the application. This feature ensures that the caliper will look as good as it works throughout its lifetime."

There seems to me to see in the photo that has two holes that I suppose they go in the spindle, although the photo also sets "Image in May vary from actual product"


Another "small" problem is that I live in Spain and have not chance of obtaining the pieces in junkyards, the American cars do not abound somewhere here  

the change would be interesting to 12,19 but that forces me to change the rims of 15" into others of 16" or 17" with his respective tires, which would be an important extracost.
I will send a mail to Centric to clarify if the caliper adapts  to OEM spindle

Greetings to all

Thats what Idid but went with adavance auto parts crap !?

The adapter on the centric caliper is not large enough to bolt on to the stock mopar spindle. You need to have 3.625 inches of space from mount to caliper bolt to clear the 11.75 rotor. picture of this below.

12.19 rotors are actually the biggest you can fit inside a 15" wheel. This is what the nascar guys run. However, they may not fit inside all 15" wheels. Any rotor bigger than that requires bigger wheels. The 13" rotors popular with the pro touring crowd require 17" wheels, but a 12" one may still fit in your 15".

Another option you can consider is calling Wilwood's tech line and talk to them about the pad compound you have. While you do have smaller rotors, they are the same size as the small stock units and should provide adequate performance unless you are repeatedly using the brakes like a road course race. A chang ein the pad compound can raise or lower the optimal operating temp of the pads to more closely match the driving you are doing and raise the performance of the system.

The spindle used on the 2nd gen Chargers used the small wheel bearing.  To use the later unicast rotor, you need to change the spindle.  The original disc-o-tech article said to use the spindle off a 73-76 A body as the distance between the ball joints was exactly the same.  And it cautioned against using the later spindle since it was 3/8 inch taller.  I think this has been debunked now so you can use the later spindle without worry.  So buying the complete Cordoba setup as recommended is a good idea.  Of course, there were 10.87 inch rotors and 11.75 inch rotors and each used a different caliper adapter.  In fact, there are 4 different ones since there were both "pin type" calipers and "slider type" calipers.  Nothing wrong with the pin type except they don't make good pads for them and they do for the slider type.  I think the pin type were discontinued after 74 so you want the big brake setup off a 75 up Cordoba or equivalent.  Now if you get hold of the spindle then you have this option:

which is pretty interesting.  But a lot more expensive than using all Mopar stuff.  What to use may depend on how you are using the car and what demands you are putting on the brake system.  Many say that if the brakes are set up properly, that you don't need a power booster.  If you want one, you will not be able to find the Bendix 8 inch dual diaphram unit (they are scarce as hen's teeth) but other Mopar boosters will fit and work---just won't look correct if that's important.

Hello, I have got contat suport  with Centric, and Posi Quiet calipers comes with the adapter for the spindles
The second step will be to play it to me, to buy them and to hope that they should fit well 
Soon the following chapter...
