This is a LONG-STROKE Type 20 with a 2.00 in brake adjustment limit — a standard-stroke Type 20 has a 1-3\/4 in limit, and the two must never be mixed on the same axle. Long-stroke chambers are identified by a trapezoid tag, square air ports or an \"L\"\/\"LS\" stamp per SAE J1817. This is a SERVICE chamber only: it has no parking brake function and is not a substitute for a 20\/20 or 30\/30 spring brake. Note that a 2.50 in stroke is LONG for a Type 20 but STANDARD for a Type 30, so stroke length alone does not tell you the classification.
