Rear Disc Brake Conversion
Has anyone done a rear drum to disc conversion on a 1981 F150-2WD Pick up?
I have been getting many conflicting opinions:
1-You have to change the master cylinder-
2-Master cylinder is OK-but you have to change the power booster
3-Master cylinder & power booster is OK,but you have to change the proportioning valve
etc........................
Any ideas anyone.
HELP!!!!!
Thank you.

I know there is at least one thread that tells it all.... I'd look in the brake or axle forums as well. Seems like all the parts come off a Lincoln. As to WHICH parts... can't recall for sure so I don't want to give you bogus info.

You will definitely need to change the master cylinder and prop valve. An adjustable prop valve would be best. Drum brakes require much more pressure to be effective than disc brakes. The booster should be fine.
Are you swapping in a factory 9" disc brake axle from a lincoln or going with an aftermarket kit?

Rear Drum to DiscConversion
I would like to keep my stock rear axle-IF POSSIBLE.
I am trying to save money,so used parts would be fine,but we can't sacrifice safety for a few bucks.
I need someone knowledgeable to say which used parts I need or where I can purchase a kit.
Thanks to everyone.

In this forum ( brakes, suspension,etc) do a search on "lincoln" you'll see a few threads that should help as well as links to sites on this subject. I see mustange70 is either in the process or has done this.... eithre way he's in it deep enough to give you a heads up on his experience...
