I have a 89 toyota pickup, with a v6 and i recently purchased a 85 front toyota axle and will be rebuilding and using it to sas my truck but was wonder if there is anyway i can use the IFS calipers. Im assuming i will need different rotors? What else should i know?

I'm also planning to upgrade my front brakes on my 85 Runner. Came across this in another forum/site:

Weak link:˟Front brakes on solid-axle vehiclesModels affected:˟'79-'85 pickups and 4Runners

What happens:˟Solid-axle-equipped vehicles have non-vented front brake rotors with small calipers. After adding large, heavy tires, these brakes only provide marginal stopping power.

Sturdy fix:˟Fortunately, there are factory parts that offer improved braking performance. Larger calipers from an '86-or-newer pickup or 4Runner can be used with vented rotors from an '81-'87 FJ-60 Land Cruiser on solid front axles. A larger-bore master cylinder from an '88-or-newer V-6 Toyota is also a bolt-on replacement. Additionally, all of these upgrades will still fit beneath your 15-inch wheels.˟

Contact:˟Your local parts store or wrecking yard

No infringement intended, and I hope it doesn't break some rule or whatever. But it helped me with my decision, so figured I'd pass it on for what it's worth

^^yes you can still use 15" wheels but you may need to use wheel spacers to clear the IFS calipers depending on your back spacing.
OP: most generally go with 1.5" spacers so your front track width matches your wider rear IFS width axle...86-95 rear axle 3" wider WMS-WMS than the 79-85.

Good man! I wouldn't have known that.
