Double Checking the Process - Disc Brakes - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Garage Freak · 01-12-2008, 05:15 PM

I just bought a 72 3/4t frame to strip the front disc brake spindles. It is my understanding to put them on my 70 3/4t I need to replace my current style of ball joints with the 72 ball joints. Also I'll need to use the 72 tie rod ends as well. I take it that I just need to swap out the outer tie rod ends only?
I noticed that the brake lines are routed from the front on the 72. I guess while I'm having all of this fun it would be prudent to follow suit as well. Of course I'll need to swap out the porportioning valve to keep from scaring everyone when I brake at the lights (including myself).

Do I have this right? Anything I'm missing or should be doing extra?

I'll be posting on the Parts for Sale forum for the rest of the frame if anyone is interested.

Thanks

I think you need to do the Master cylinder also.I'm not sure on the 3/4 but there should be a thread in the FAQ's that will refine your swap.

Thanks PanelDeland. I looked in the Suspension forum and gleaned out what I had described. I'll check out the FAQs. Thanks

if your wheels are original, you'll need new ones.

Longhorn Man,

You mean that it was a good thing that I bought some later model rims? I guess I'm smarter than I thought!

Thanks,

LOL! Yep, you knew what you were doing before you knew what your plans were!
