Louisiana | 98 Freightliner brakes will not release sometimes. Push yellow button in, will not stay in. Other times will release, but pull out and brakes will not engage. After a few seconds they will lock. Once engaged or released will hold either way. Have changed valve in cab a couple of times with same problem after changed. Removed several lines checking for moisture/debris clogged lines. All look good.Truck is set up as a tandem with 22 foot box.Not familiar with troubleshooting air brakes. Any advice appreciated. | |
