Disc Brake Swap... Mill the Axle Flange
#22
try the caliper off a 95 lexus sc400. it's a 2 bolt caliper. one on top and one on the bottom , pads just drop in fit. you will need a 16" wheel to clear them as that's stock

RBX i don't wanna jack your thread but there's to many threads all over the place about the same subject.
but wouldn't it be easier to grab front calipers,lines of another truck ? or would the braking be different ? i've got my 89 dlx that i've used most a few parts off , wouldn't the fronts work for rears on a 86?

Subscribing. Rear discs would be real nice, but the e-brake problem always turned me off. The extra $300 for a t-case brake also made the project expensive. If you can pull it off and keep the e-brake at caliper for a decent price, it may be something I have to try in the future!

The milling the axle flange is why I started this thread. I think Wabbit commented on another thread about turning down the flange, IIRC.
The caliper thing, yes front brakes will work, any caliper could work really, but I wanted to use the side pull e-brake, but those calipers are very hard to find, seems that they have all changed to some other online pull probably to eliminate yanking the caliper inwards.
I have looked at a set of 2wd calipers from an 83 yota because they are full floating, a piston on each side. This type of caliper makes changing pads very easy, much like the front four piston calipers found on my rig. The downside is that they must move more fluid to squeeze the rotor and that directly impacts pedal feel which is related to the MC size.
It looks like I will run some type of non e-brake caliper and use a t-case brake which will set me back 200 bones. This is going to make the conversion take longer.

If you're feeling ambitious:

BTW where do you find the t-case brake for $200? Both Sky Manufacturing and All Pro list it for $250+shipping, thus my slightly exaggerated $300 estimate.

Z, you are right about the price, I was just ballparking.
I'll check the link, and I have thought of making my own, I have a couple bike rotors I could use.

True, on a bike.
I was measuring my bike rotor and it 12.25", way too big and probably too thin.
Not sure if im gonna fab one or not, but it seems my IFS may interfere with an off the shelf product.

Anyone know if I can use a caliper meant for a vented rotor on an solid rotor?
I have solid rotors and want to make sure the piston haze enough throw to be used on the solid rotor.

rockauto.com shows a selection of rear calipers for a 79 celica supra....many of them with brackets/pads
Lots of cars use integrated ebrake mechanisms like that. nissan 200sx and 240sx. Pre-1990 subaru fronts (vented after like 1982).
You could use calipers designed for a thicker rotor (vented), but as your pads wear out, you risk hyper-extending the caliper piston and blowing the seals. you might be able to make a spacer to prevent this, but then you risk pushing the pad base off the bracket, which would be very bad.

Thanks, what you stated is exactly what I'm afraid of. I'll check rockauto again, some that show they have it, tell you when you add it to the cart that it's unavailable.

hey man so i did a little research on this a while back (looked thru cars at the pick n pull ) the ford taurus has the rear calipers with e brake along with a few other ford models that use the same one sable ,cougar ,continetal, mark V11. the ones i measured would fit the solid rotors . not sure how well they would work because i never got around to trying them , but there was a crap load of those cars at the junkyards. these were late 90s early 2000 models .

Thanks
The issue I see with those like many others, is that the ebrake cable will need to be seriously modified, not sure if the donor car configuration would fit.

Did some more research and no matter what calipers i go with, i will need to modify the e-brake cable route and fab some brackets to use a caliper style parking brake. this is a cheaper route then the Sky or All-Pro trans brake. I really like the idea of removing the cable from the rear axle, and getting it out of the way.
So what if i used Wilwood Parking brake caliper, like this:
Anyone see an issue with this? this setup will be half the cost of a t-brake, however, i will still need to fab some brackets. If i go this route, i could move the calipers anywhere i would like, perhaps eventually relocate both the rt and lt as a t-brake if i so desire....what say you?
EDIT: i am simply refering to the mechanical caliper, as i will probably run a Toyota caliper like this on the rear, makes changing pads easy.

Many hi-performance brake setups use this configuration, probably because:
a. Drums are heavy
b. more empasis on rear-hand-braking
c. Multi-piston calipers cannot(or i have never seen) integrate a mechanical caliper
