Who Knows About Adapting Rear Discs
Does anyone know if any late model Lincoln, Mercury, Ford automotive rear disc brakes will bolt right up to an F150 rear backing plates?
I talked with an older mechanic who told me, "Any late model Ford Disc Brakes will bolt right onto your rear axle!"
He showed me a late model rear 8-inch axle that he had bolted some '01 Lincoln disc brakes onto and I about fell over at the simplicity of the adaptation. How simiple.
Does anyone have any similar knowledge?

You might be able to bolt the assembly onto the axle housing but it does'nt end there.
What about things that need to be connected like the emergency brake cable, and the brake fluid lines going to the calipers?
They most likely need to be replaced with hoses as opposed to the hard line that screws into the rear wheel brake cylinders.
Will the proportioning valve meter the fluid to disk brake calipers properly with the same bias as it would to the wheel cylinders on the drum brake setup? If not then your rear brakes may either lock up of become totally ineffective when you mush on the brake pedal.
Will your wheels clear the calipers without rubbing or binding?
I like the look of rear disk brakes especially when you have nice rims that let you look through them to the discs. But I've hade a troubled history with cars that have rear discs, (caddies & lincolns) having them sieze up or the emergency brake mechanism get hung up, and you have to screw the piston back into the caliper when changing pads on the rears whereas the fronts just get compressed. To me the drums just seem more trouble free on the rear end.
But hey, that's just my opinion and I'd e lucky if it was worth even two cents! I'm not tryng to discourage you from trying but be aware that there a lot of other things to consider besides just bolting the assembly onto the axle tubes. Make an informed decision because the demons are in the details.
Good luck

Thanks Le Pew .... That is some good advice ....
I have talked with my mechanic and he said I may have to install a different proportioning valve and a dual resevoir brake sylinder.
Then, like you say, there is the problem getting the emergency brake to function again. So, there is more to it that meets the eye from the onset. Thanks for your insight.
And, when you think about it, the drum brake isn't that bad.
