Topic: Brake Upgrade Question

[myyota]

Are there any brake upgrades for the front bakes on an 85 solid front axle truck ?, i know about swaping over to the vented rotors and v6 calipers, but are there any 4 piston calipers off another car/truck that would be a direct bolt on for my stock 2 piston calipers ?. ive already swapped in a duel diaphram booster off an 89 truck and that made a noticable difference, so im just trying to find out if there is anything else i can do short of spending money i don`t have on the new rotors and calipers.

aren't the v6 calipers 4 piston?

V6 IFS front brake calipers. 4 piston, originally found on 1988-1995 V6 trucks. These are the perfect calipers for upgrading the brakes on 1979-1985 front solid axles.

Note: Calipers may require the use of wheel spacers when used on 79-85 solid front axles.

Can you use the V6 calipers on a solid axle truck with out swapping over to vented rotors ?.

Even if you could why wouldn't you want the vented rotors? They aren't that expensive and it's worth the effort of installing them.

All the calipers from the solid axles and IFS were 4 piston calipers. The difference with the V6 calipers is all four pistons are large pistons where as the 4cyl pistons are 2 large and 2 smaller pistons. and the reason for possibly needing wheel spacers with the V6 calipers is that those calipers have large cooling fins on them which can hit the wheel when bolted on. Some wheels vary in design and may or may not bolt up without wheel spacers. As far as which rotors to buy...if you're using your solid axle hubs you'll want rotors from an '81 land cruiser. it all bolts up and the only thing I did to mine was grind the backing plate a little (about 1/16")to clear the caliper to get it to bolt on. That's it!

How do these calipers and rotors fit with wider ifs style hub bodies?  On an 85 4wd.

If you were to use the IFS hubs the difference in the hubs (solid axle vs. IFS) is that the IFS hub wheel mounting flange is further outboard than the Solid axle unit. Also with that the rotor is moved out as well and then you can't bolt on the caliper to the solid axle knuckle assembly with the rotor further out. However, there is a spacer available from Skyy mfg (and possibly others) for the rotor to realign further inboard for the caliper to fit. It's not cheap though  . You can achieve the same results for a lot less money by buying the FJ rotors and wheel spacers than to buy the rotor spacer set up  . Or.. you can make your own rotor spacer as some people here have done  . You may have to do a search on it to get that info as I have not done that mod. The hubs are interchangeable with the exception of the wheel seals on the back of the hub (use the solid axle seal in the IFS hub when installing on a solid axle knuckle). Bearings and lockout hubs fit either, but you need to use the lockout hubs that are for the axle you're using since the shaft splines are different between the two types. Have fun doing your upgrade, I know I did

In all my research, I never caught that little bit of info.  I found out the hard way. 

So I just thought I'd quote it.  :O

Oh, here.  Read though this.
