Leroy 0 Posted December 31, 2020 Share Posted December 31, 2020 I am working on a Mack dumptruck. For the first time in my life. When I press the brake pedal the brake pedal will not go down. Do I need to replace the piece that all the brake lines are running too? Quote Link to post Share on other sites

Bad treadle valve or a stuck pedal hinge? Quote "Eagles may soar, but weasels don't get sucked into jet engines." Link to post Share on other sites
