MCHAM Posted July 24, 2011 Share Posted July 24, 2011 One of my tag wheels (lift axle)keeps locking up and wearing out the tire. I had the brake adj, but it still keeps locking up when down. Thanks for the help. Quote Link to comment https://www.bigmacktrucks.com/topic/19884-tag-wheel-locking-up/ Share on other sites More sharing options...
theakerstwo Posted July 24, 2011 Share Posted July 24, 2011 maybe the rest of the brakes ant holding and you may need to put more air on the lift axle bags.

slpwlker Posted July 24, 2011 Share Posted July 24, 2011 Sounds like you need more down pressure. What kind of pressure are you running in the axle. I know every application is different, But I am running between 90 and 100psi in mine. If your running 50 try 55 or 60 Quote Link to comment https://www.bigmacktrucks.com/topic/19884-tag-wheel-locking-up/#findComment-82340 Share on other sites More sharing options...

With too little force there isn't enough friction and the tires begin to lock up.Check the pressure adjustment for the lift axle. Drive around and keep bumping up the pressure until the wheel stops skidding. Quote -Thad What America needs is less bull and more Bulldog!

If you get to light in the front try to load farther forward if possible. Is this in a dump truck? I've seen trucks in Indiana loaded up to the headboard and not much towards the back Quote Link to comment https://www.bigmacktrucks.com/topic/19884-tag-wheel-locking-up/#findComment-82359 Share on other sites More sharing options...
