I am lookin to conver the rear brakes from drums to disc. Drums are a royal pain in the a** and i am tired of em. I want to have a good set of brakes on the back of my truck. Any suggestions as to how this could be done? A buddy of mine said the same body style 97-03 F250 rear discs might work. Thoughts??

 

I'll look forward to this. I know the emergency brake is totally different and might not be useable after the swap. Also there should be some kind of proportioning valve that would need to be changed but it might work the way it is. I also think the brake hoses need to be the newer disc brake ones. I have a set of rear disc's I'd like to swap but haven't done it yet and look forward to seeing if anyone has.

 

F250's are 8-lug and will not work. You will have to find an aftermarket company that makes a kit....or fab your own mounts

 

So does anyone know of any aftermarket companies that would make mounting brakets for this conversion?

 

Can you just get a axle out of a 99 with the brake setup on it?

 

A 99 or newer axle is the best route. I bought disks from a 99 and found it will be some custom work to install. The disk rear also has larger wheel bearings which gave it greater load. The bearing had to be smaller to to accomodate the drum brakes. I would sell my set for $50 bucks if you are still interested. In the Kansas City area.

I bought the disk from a guy who put a 98 drum in a 99 disk to replace a bad rear. So I am confident the 99 will go in a 98. 97 I would think as well. You do want the cables, they are different on the axle end. Same on the truck end.

 

I guess we need to clarify some stuff, I assume F250 was a typo since '97-'03 were not congruent years for the F250. '99+ F150's came with rear discs, although some still had drums. I know others on other sites have put '99+ discs on '97-'98 F150's but they didn't have an ebrake after it was done. Also somewhere in '99-'00 Ford went to 14mm studs, previous had 12mm studs.

 

I assumed f150 as well. obviously

about the e-brake. The cables I have with the disk back plates will tie into my 98 e-brake. So I from what I see from putting the parts up against the existing cables, the e-brake should still work. The fact that I have not done the swap means I would be missing something very obvious. The disk to drum did have e-brake as well??? If the cables are cut and not disconnected, as we know all junk yards do. lol Then e-brakes would be lost. Larger studs in 99+ makes sense to go with the higher payload of the axle.

 

i was chatting with my friend about doing this conversion. He suggested just dropping the entire rear end and replacing it with a rear from a 99 or newer f150 that already has disks. My question now is, does anyone know where I would be able to pick one up? I also am lookin for one with limited slip in the back. Havin an open rear sucks when goin off roading...

 

Check with your local scrap yard. They will have a locating system if they don't have one in stock. Recommend that you get one with 3.73 gears. Look for a B6 tag code. Good luck!

 

i have a 99 and i have drums on the rear

 

Is his truck a 4wd? If so he might need the H9 axle(or B6 depending on current ratio)... but if its 2wd, definetely try to find one with B6.

 

A 99 with drums, always something with options isn't it. Could your 99 be an early model (or late 98)?

 

i have a 4x4 with an open rear. I think it has a 4.10 rear... that sounded a little high to me, but i called the local ford dealership and thats what the guy told me..

 

When i borke my rear end the second time i found one at a salvage yard for 1000, had 18000 miles on it. Got everything included, brakes, rotors, pads, lines. Even had the same tag on it mine did. 3.55 LS. very easy to change out.
