8.8 disc conversion

[Shaggy]

i wanna get rid of the drums in my 2000 f150... it is the last year they put drums on there... i am thinking i can just find like an '01 or something in the junkyard that has the discs and it will be pretty bolt up but am not sure... has anyone swapped out discs onto an 8.8 this way... does it require aftermarket brackets like all others? will the stock master cylinder be big enough?..... tell me what you know

i think that the master cyl should be fine. but if your going to upgrade to disk anyhow, why dont you just find a 9.75 and put that in. upgrade bothways.

9.75s are obsolete now. they went back to the 8.8 for 2004 or 2005. i'll look in the yards for you Tate, see if i see one. FREE....if you take it off my tab. :gigem:

[william_ace]

obsolete or not, it'll still get the job done. I'll betcha either is not hard to find.

this is for a 2wd daily driver... i dont need anymore than the 8.8... and if you find what i need it will come off your tab

the master cylinder and/or proportioning valve should be different...

drum brakes need residual pressure on the wheel cylinder to prevent leaking, this is normally around 5 psi if i remember correctly. This would make the calipers in the rear drag. There is another problem also that i can't remember exactly... something to the effect of the rear drums only coming on when the front hit a certain psi. I can't remember what this affected, but i remember something about it.

With that being said, on the blazer, i gutted the proportioning valve of both of these and installed a adjustable one in the cab. Other people do nothing with the disc brake conversion and it works fine too, so who knows.

If i were you I'd just compare the master cylinders in the parts stored and then get the proportioning valve from the truck that you get the axle from.

i dont think this is true.

i think they still have the 9 .75's to but not 100 percent sure cause if i remember the ford comercial withthe truck frameand rolingchaisis bouncing over the hums the axle looked like a 9.75, but i kinda agree with will you could prolly get a whole axle tate and save on some work on your part. just a thought.

i think that is what austin is gonna try to find for me
