Questions about Drum to disc conversion

Post by crozetiga »

I just bought my donor truck today for disc conversion on my 70 f100. Now I have questions... several

I have limited income(at least my wife says its limited when it comes to buying truck parts) so I have to save up alittle bit to buy all the parts i need for the conversion. Does anyone have a parts list of things that you need for the conversion and approximate prices.

I have thought of these items but have no idea how much they cost. (I could look them all up but if someone had a list already made up that would be a heck of alot easier):

Kingpin kit
bushings for rear connections of the I beams
axle pivot bushings
(can you buy a kit with all of the front end bushings?)
new calibers
new rotors
new wheel bearings
rubber brake lines
metal brake lines
connectors for metal brake lines
bending tool for metal brake lines
flaring tool for metal brake lines
Cost of having a machine shop ream and reinstall kingpins


Is there anything that I am missing? I am sure there is.

If the tie rods on your donor truck are worn out you will need those, too. A new set is about $150.00. You might be able to use some of the steel lines from your donor. Is the master cylinder/booster on your donor useable? A rebuilt one is about $130.00 exch.
Rotors--$45.00 ea.
Kingpins--$50.00 set
Calipers-loaded- $45.00 ea
Bushings-- under $50.00

are your current caliper no good? if there good then why get new ones? unless you just want to make sure you don't have to mess with them for a while. if they work now and money is tight then use the old ones for awhile if you can. and don't forget to get the frame bracket for the brake lines. this is so the lines won't rub on the wheels. or get in the way or get too much vibration and cause damage to them.

If you are on a budget, try to reuse/repair all the pieces and parts that you can. Calipers and master cylinders can be successfully rebuilt if needed, rotors can be turned if still in spec, brake lines reused if not corroded, and king pins don't need to be replaced if still in good shape. I think that 1) wear parts like bushings and brake pads should be replaced and that 2) some of the new parts we have to use are not as good as some of the used, OEM parts on the trucks. Of course if you want new, then save your money and do all the work at one time. :2cents:

I'm at the end of my disc brake conversion and so far i've spent $70 bucks, and that is really lookin to be about all i need to spend, all the steel lines were reusable, i'm getting new rotor/hubs for 25 a piece, calipers for 10 a piece, and i took the kingpins out myself, and a friend with a press and reamer is gonna reinstall em for me, bushings cost me 42 bucks for the Energy Suspension polyurethane ones, check out www.energysuspensionparts.com, good deals there. Try to be as economical as possible. Check your friend network and see if you know someone with a press, the guy doin mine i didn't even know he had one! Good luck!

If your working on a tight budget, you can save by lookin at what's good
to keep. You don't want to cut corners on brakes. The rest of these trucks
is so over enginered/built, that you can repair/upgrade later. With any
hydrauic braking system the master and slave cyl's have to work. The
pads and rotors have to be in good shape. Safety first. :)

yes you should use the newer porpotioning valve with the swap i would think. for better equaization of the braking power to each wheel.

:yt: because otherwise your rear brakes will lock up before the fronts start working. these trucks have enough of a problem with that, already!
