Haldex slacks may back off
WASHINGTON, D.C. – The National Transportation Safety Board (NTSB) is advising trucking associations, CVSA inspectors and others to thoroughly inspect automatic slack adjusters made by Haldex. The problem, according to the NTSB, is the product’s control arm may fracture or come loose from the adjuster. If this occurs, the unit will stop adjusting the brake. The NTSB refers to this situation as “deadjust,” and implies the auto slack actually backs off. NTSB’s concern comes from a fatal bus accident near Atlantic City, N.J., in 1998 in which eight passengers were killed. While the NTSB investigation ruled the brakes weren’t to blame, it found the right-side brake “grossly out of adjustment”. n
