I don't disagree that ABS isn't intended to manage every day out of balance brake systems. I ran a year with no ABS in the rear and the only time I ever had the rear lock up was in pretty heavy rain, we don't get snow in Tucson. So balance is very important and the use of a proportioning valve is a great part of the process. I have said many times that the rear brakes of a 3rd gen work great when functioning properly but the rear disc do give an upgrade in stopping power but it is a lot of work and unless you really need the extra stopping power it is not worth it. I just really enjoy the discussion and was in no way trying to bash or disrespect @rideexileex .

Just another thought I have had is that 4 wheel ABS systems are designed to work at much higher stopping (clamping) power than older systems that simply relied on balance. So not having a functioning ABS system actually decreases the stopping ability of our 4Runners. I am happy to have figured out how to have ABS on my rear axle once again.
