TRUCK SERVICE MANUAL TM 5-4210-230-14&P-1 BRAKES-PARKING Fig.   2 Parking Brake  Adjustment in the Orscheln Hand Lever ADJUSTMENT Adjustment of brake will be required when replacement of lining, shoes or drum is required. Refer  to  Figure  2  pertaining  to  the  nomenclature  in the following adjustment procedure. 1. Block wheels to prevent vehicle from moving. 2. Position    parking    brake    hand    lever    in    released position (forward). 3. Assemble  control  rod  with  yoke  to  brake  lever  bell crank if disconnected. 4. Move  brake  operating  lever  in  apply  direction  to  a position  where  contact  is  made  with  the  brake  cam but  without  any  shoe  movement.    This  will  remove excess clearance in mechanism (approximately 6.35 to 9.53 mm, 1/4" to 3/8", free play at lever). 5. Adjust  clevis  until  hole  in  clevis  aligns  with  mating hole in bell crank. 6. Assemble   clevis   to   bell   crank   and   tighten   clevis locknut. 7. If  vehicle  is  equipped  with  Orscheln  parking  brake lever  (over-center  type),  turn  adjusting  knob  on  end of hand lever until a force of 41 kg (90 lbs) is attained to apply the parking brake. The Orscheln (parking) brake lever is the over-center locking  type.    It  is  tightened  (while  released)  by  turning  the adjusting  knob  clockwise.    When  properly  adjusted,  it  pulls over center with a distinct click. PARKING BRAKE BURNISHING (W/Orscheln Lever) The following burnishing procedure is required to be performed  on  new  vehicles  or  whenever  the  parking  brake lining and/or drum is replaced. Vehicles with Orscheln Lever 1 The vehicle must be loaded near rated GVW. 2. Release  parking  brake,  turn  adjusting  knob  until  a force   is   obtained   to   apply   the   brake   (over-center position  of  the  lever)  which  will  result  in  the  vehicle making  a  somewhat  lighter  than  normal  stop  (3-5  ft per second) without wheel lockup. 3. Make ten (10) stops from 16 km/h (10 mph) on a dry hard  surface  road  using  only  parking  brake  to  stop vehicle. 4. After   each   stop,   release   parking   brake   and   drive vehicle at 32 km/h (20 mph) for 4 km (2.5 miles) to cool the brake. 5. Readjust  parking  brake  linkage  (between  hand  lever and  brake  assembly)  and  hand  lever  adjusting  knob to suit operational requirement considering load and road grades for vehicle operation.
