Isn't the ABS sensor a ring on the axle shaft just inboard of the bearing? One of the sites listed, either FROR or Sky indicates you should call to get the details on working with it.

Also - I inquired at Rockstomper about his ubolt kit a while back at which time he told me there's two different tube sizes for T100s, 3 and 3.25". I imagine that would have some bearing on whether these kits will work on all T100s. Maybe? Maybe not? I know it screwed me in terms of the flip kit.

he got me ubolts. i think he ended up finally finding them through superlift or someone.

The ubolts weren't the issue. I can get whatever I need bent on the spot up here. It was the tube diameter being different from one truck to the next and that the mounting plate arrangement from him fits a 3" tube but not a 3.25". I just wonder if that sizing difference would also have a bearing on whether these disc kits will fit all T100s.

he custom made me the top plates.

The housing ends, where the brake backing plate bolts up, should be the same for all T100's (and all the other non-rear disk brake Toy 4x4's), and therefore all the rear disk kits should fit. (The 4th-gen 4Runners w/ factory rear disks have a completely different axle housing end and bolt pattern)

The only difference I can see is the ABS models have the sensor in the way, so probably what they do is mount the calipers on the front side of the axle instead of the rear, which also requires you swap the calipers left/right so the bleeders are still on top.

The sensor on the ABS axles is right about where the brake line is in this pic:


You might even still be able to fit the bracket in the back if you did some grinding on the bracket...? I just looked at my '97 Runner and it looks close...
