I'm looking into swapping discs onto the rear of my 3rd gen. Sky's kit is my top pick atm, but I may just buy some brackets and make something up. My question is: If the abs sensor and "ring" are INSIDE of the rear axle housing, and the disc brake conversion is happening OUTSIDE the end of the tube, why is everyone losing their ABS? What I am missing?

Everything I have seen/read shows simply sliding out the axle, unbolting the drum bs, and sliding it back in to add disc components, I see nothing happening past the 4 bolt end of the axle tube.

Somebody educate me!!

Why? The 4Runner has no weight in the back. Converting will do nothing.

lol! you are joking right??
nothing but update old school drums to modern more powerful brakes that wont fade and loose power even after a water crossing. as a bonus you can remove and replace axles for seals/bearing or diff service in less than half the time..
why do you think nearly all new cars and trucks have 4 wheel disc's?

OP, you should call skye or trail gear that sell the kits for info. i have had good customer service info etc from trail gear when i have questions about their products.

The ABS should still be functional. In fact, it is more important that it is functional from safety point of view since stronger rear brakes could possibly result in rear skids during sudden braking, wet road conditions, and unladen rear.

thank you! I regularly load my runner with camping gear and/or pull a landscape or snowmobile trailer. But.. I also daily drive my rig so all around safety is important to me.

more research has yielded some results...

It may be possible that with clearancing of the caliper mounting bracket and/or rotating the bracket it may be possible to leave the abs sensor intact. Most guys don't care about abs enough to bother doing this, but for a DD rig in an area with yearly inspections, I need my abs intact. I will post up more once I get it pieced together.

FROR Full Float Conversions

Rear discs....

I bought a set of those brackets a few years back. The sky el-dorado ones. Yes you would need to modify the bracket or have the caliper on the bottom side to make it work. Our housings have "square" edge on them where the ABS sensor goes in.

If you get past that hurdle, good look with the E-brake cable routing. You will have to get creative. Not to mention you will also need to add a prop valve or residual pressure valve or else your pedal will feel like crap.

I ended up selling the brackets to DrSmash since he had an older pickup to put them on and I went the FROR full float route. Which lead me to adding an adjustable prop valve and now I am looking at a larger booster and master cylinder.

So all in all, if you don't offroad your truck heavily enough to justify the full float kit OR you dont need an e-brake, just keep the drums.
