Drivers side PST T-bar will not seat completely

Don't grind anything. If its to long send it back. If the lower bushing is tore replace it. Poly bushings push the arm back when hitting the brakes in reverse. Its a common problem. One reason they said in there instructions not recomended uneven roads . Go figure? Have new factory style bushings install by someone that knows how. There should always be a space between the bar an the clip. They expand and contract when twisted. I never had one just fit they are always shorter then the clip when installed. Grind it and see what they tell you if it breaks when you try and return it. Its a spring , Never grind or grab it with anything with teeth. Good luck with comments after this.
