with the ABS system on these trucks if I remove the rear calipers and plug the lines will there be any issues? I dunno if removing the calipers will throw any sensors out of whack and cause issues with the front brakes still working normally.

 

my first question is WHY?

and it might mess up because when the front brakes go to stop more than likely they will lock up, therefore causing the abs pump to engage and will pulse the front calipers to make the front wheel speed match the rear wheel speed, this makes your stopping distance way longer than it needs to be and can cause you to rearend someone or hit something..... also if you plug the rear lines i would assume the pressure built up in the lines will get bypassed in the master cyl and will cause below subpar braking performance.

 

pulling truck...dual wheels wont fit over calipers. removing calipers for the 2-3 times a year i run duals. when the single wheels are on I can bolt the calipers back on and do a quick bleed on the rears and they are usable again.
