I'm looking to convert manual brakes to power brakes do I need new brake lines? I've already converted the front disc brakes and I also want to convert the back to disc brakes. I have an 8 3/4 posi rear, all wheels are small bolt pattern. I was also wondering if someone can post a link to a brake system that I can use for a 1970 Dodge Dart It had a six cylinder and that has been changed to a 318. Thanks guys. oh also i have an adjustable portion valve is that ok to use? Or do I need an original.

 

Welcome to the site....


SSBC. Might help on the brake conversion.>>> http://ssbrakes.com/
Check the Vendor Directory up at the top of the page also for some help on the parts..


As for the 70 Conversion... Find a doner car like a 73 Dart or Scamp or Duster and pull all the hardware from it to change over..


Just my thoughts....

 

The small bolt pattern will limit your options most convert to the 4 1/2" pattern Brake lines & prop valve should be fine as long as they are not rusty..+ If you already have a 8 3/4 you should ??? convert to the 10 X 2.5 drums the smaller 9" drums are getting impossible to find which work Great. I would not put disks on unless you have money to burn. Can be better spent in other areas

 

So the 10" x 2.5 drum will fit the small bolt pattern? Do you know where I can buy those drums? If you do can ya send me the link for them? That would be so awesome. Thank you for your help.

I meant 10" drums if you upgrade to the 4 1/2 pattern
