Convert DRUM to DISC brakes?
I finally found a car with independent front suspension (old Toyota Corolla Station Wagon), so am interested in the upright and hub. However, it has
drum brakes in front.
Is it difficult to change this to disc brakes? I would think I can just get an aftermarket disc brake and "bolt it on"?
Or should I go looking for another donor car part that already has disc brakes? (The problem is that it's kinda hard to look for a car with IFS,
as most have a mcpherson strut).
Thanks!

FANTASTIC!
Sometimes, I forget that donor car doesn't necessarily mean sedan -- been looking in the wrong places, I guess.
Now gotta hunt down all these lite-aces and hi-aces...
THANKS MUCHO!

there should be a few in your neck of the woods I used a lot of the van i aquired
uprights diff about 4:1 ratio tailshaft mastercylinder and booster the brakesystem even has a hydrolic proprtioning valve to adjust your brake
ballance. build the car to book width (making the front suspension a little wider to keep the f/r track the same and you acan use fwd ofsett mag
wheels which are a lot more common these days
hope this helps
best wishes

Well, I got myself uprights (with disc brakes) from a Toyota Crown, and a live axle (with disc brakes, too!), also from a Toyota Crown (apparently,
the guy there said it's the same thing the hi-ace uses).
Of course, now I have to find 5 lug wheels... 
Thanks for the tip!

Well, I managed to return the Toyota Crown axle and front uprights, and changed it or a Toyota Town-Ace axle and uprights. The Crown stuff was
actually more expensive, but they didn't give me any money back -- but at least I have more appropriate stuff.
The Town Ace rear axle is also a LOT lighter than the Crown live axle, which was a big consideration.
The track of the rear axle is 50" (not accurately measured, but measured with a tape-measure nonetheless). It's also a nice 4.3 ratio,
which should go well with the 4AGE-20V (silvertop) that my friend is trying to get for me.
