Rear disc brake conversion

[82fordtruck]

the srw's are semi floats. the drw's are full's. We know the rims are the same between the vanner and the pickup, so the fitment is not the issue. I'm not suggesting using the whole axle, just the brake parts. problem is, I don't know of a single full service wrecking yard that will part out a perfectly good axle.

Who needs a perfectly good one?

It's like trying to get them to part out a perfectly good ZF5 tranny for the tailshaft housing ......Don't ask me how I know

One thing I did find in my quest was that the majority of these heavier duty trucks are mashed in the front Prolly becaise people don't realize that 6000lbs+ of truck doesn't stop like a Honda Civic.

Or maybe because a rear end collision really doesn't do any damage to our trucks.

ouch for those prices i would go with the kit. the cheeper axles dont guarantee anything is there but the center. so it probubly wont have brake parts unless they wouldent be any good....

82ford-
I've worked both sides of the counter. around here, nothing gets pieced out unless if there is a really good overwhelming reason to do so. personally, I've seen enough shattered axle housings to know I don't want to buy parts off one. But hey, its your $$$$ and well being at stake. I don't do ebay either. If I am going to lay out my hard earned money, I'm going to touch it and feel it first before buying. I've learned my lesson once on buying a truck sight unseen and won't forget it anytime soon. Yes, it's true I did buy the '92 sight unseen, but the price point was good enough that if the motor did scatter(and it did) on my way back to Kali, I wouldn't feel bad. Unlike Gary/Icanfixall who's ebay horror stories are well known around here, when a deal goes bad locally, I can "reach out and touch someone" and have done so

i've clicked on two of those links and he clearly states "no brake parts"

in the first part of this thread someone mentioned several of us pooling money to buy a kit. i wonder what our total cost including calipers and all would be? if anyone is still interested in doing this, i might join in

Van rotors are 8 on 6.5. Super duty pickups are 8 on 170mm. The rotors wont swap. My 2000 E350 Super Duty has a ff60 with discs. Factory. Caddy calipers are expensive and not designed to be used in a heavy truck. Chevy 1/2 - 3/4 ton front calipers and work very well for this. They are cheap and readily available. Nothing wrong with using a line lock in the hydraulic brake line. It will be a parking brake only not an emergency brake. All modern vehicles have either cross acting safety valves or front to rear safety valves built into their system. If you lose a line, a valve slams shut blocking that leak off. You lose some but not all your braking. Look up Micolock or a 12 volt roll control solenoid. Slip on 3/4 ton chevy 8 lug front rotors work well, longer wheel studs may be required. Upgrading your master cylinder to a 1 inch bore and using one designed for a rig with rear discs helps too. Adding rear discs is pretty easy. Bracket templates for the D60, d70 and 14bolt are readily available on the web as well.

Well, it was me that mentioned pooling money to do this. My current thinking is that we could use E350 rotors, calipers, and E brake parts. If needed we could swap to a E350 master cylinder and proportioning valve as well. All that would be needed past that would be the backing plate.

I'm dragging my feet because I have too many projects already and don't want to take everyone's money and not do anything with it.

 

[82fordtruck]

My comments about buying an E350 axle were that we could have the parts handy to copy them. I didn't mean all of us buy one, just the one of us that's doing the work.

Further, if anybody else wants to do this, they won't be stepping on my toes. I'll draw everything up and help them through the process. I'll pitch in $$ too.

couldn't you just swap the complete stupid doooty axle in?

Only if you want different wheels front and back.

What is the recommendations for the master cylinders. I saw no mentions of anyone changing it over to one built for 4 wheel disc. Does not matter what caliper you use if you do not feed it properly.
