Not on mine !! My truck originally had drums. If you go back on the top of this page, you'll see that I made my own disc brake conversion using large late model
2-piston calipers. On the table with the coated parts the custom backing plate is sitting on the edge of the table. I also increased the stud size to 1/2-20.

Did yours have a brake booster ? And what are the calipers bolting to ?

Mine had the original 11 booster, but now has a dual diaphram 9".
The calipers mount to a custom made 1/4" thick backing plate. I've got about 1500 miles on it now, and it stops as well as my new truck. I'm extremely happy how the conversion worked out.

Hey Hemi,

Would you mind sharing some details on this custom conversion kit? Photos of backing plate & details of the mods would be great! I also have a 70 (it's not going to be done nearly as fast as yours...) & I really like this option compared to the price of a conversion kit or replacing the entire front diff. I'll also be doing an LS swap so I will likely take the calipers of the donor truck.

Great work on your blazer - really like your color choice. Hope you're enjoying it!

Thanks,
Tom

Any pictures I have are already posted here. Even though everything bolts onto the existing hubs, there is quite a bit of machining involved. It's basically late model calipers with mid 90's rotors. The difficult part is getting all this to fit inside a 15" rim. If I had to do it all over again, I would use a hat and rotor assembly because I couldn't find a factory rotor that was deep enough to get the caliper away from the rim. I now have about 5000 miles on the truck, and have had zero issues.
