Technical Disc brake caliper bracket

I visited online POL, CPP, ECI, speedway, western ch***is..... do the all have the same bracket kits ? POL uses ECI instructions for example. Which company can you guys recommend?

 

Found an installation sheet. It gives information on bearings and race change out. Might help someone out.

 

On the GM mid size calipers:
70/72 is one design
73/76 is slightly different and I am thinking it is how the hose connects.
Metric fits 77 to end of production (84) Mailibu rear wheel drive plus a number of others.

Top to bottom. All right hand side calipers
70/72 Chevelle, Monte Carlo
73/76 GM Mid size = Chevelle, Monte Carlo, Regal , Cutl***, Lemans, Camaro
77 and up GM Metric rear wheel drive.
Note that the difference between the 70/72 and the 73/76 is the way and angle that the hose connects to the caliper. Not an issue on an I beam or tube axle but it may be an issue with control arms .


Note too that there a difference between70/72 Chevelle/monte carlo style rotor and the 73/76 rotors and that being the length of the snout on the hub. This so 68Caddydaddy has a little bit better idea of what he is looking at.

 

I did some research, it seems that almost all vendors use the same instruction sheet . Is ECI the original manufacturer of the disc brake brackets ? Is POL and CPP just selling their kits ?

 

Do you know what kind of outer bearing is used ? In the article the A13 is mentioned .....

 

It fits !
