TSDs No. 105 and No. 135 reproduce U.S. Federal Motor Vehicle Safety Standards

Systems," respectively, and the TSDs are incorporated by reference in sections 105 and 135 
of the Motor Vehicle Safety Regulations .  The new revisions replicate the regulatory text of 
the Final Rule issued by the National Highway Traffic Safety Administration of the U.S. Department of Transportation that was published in the Federal Register  on 30 June 2005 
(Vol. 70, No. 125, p. 37706).  
Revision 4 of TSD No. 105 extends the current minimum performance requirements and 
associated test procedures for parking brake systems to all multipurpose passenger vehicles, 
buses, and trucks with a gross vehicle weight  rating (GVWR) greater than 4 536 kg that are 
equipped with hydraulic or electric brake sy stems.  Currently, the only vehicles with 
GVWRs greater than 4 536 kg to which the current TSD's parking brake requirements apply are school buses.  This revision also updates the reference to the Society of Automotive Engineers' Recommended Practice J972, "Moving Barrier Collision Tests." The new revision will become mandatory on 30 June 2006,  which is the effective date of the U.S. 
changes.  
Revision 2 of TSD No. 135 corrects an error in the description of the conditions that may be 
indicated by a common brake warning light u sed in vehicles equipped with split service 
brake systems.  Revision 2 is effective as of the date of publication of this notice with a 
Mandatory Compliance Date six months later.   Vehicles manufactured during the six-month 
interim period may conform to the requirement s of either Revision 1 or Revision 2 of TSD 
No. 135.
