TM 10-3930-671-24 Brake & Inching Circuit TA18 Transaxle Figure 2.  Brake & Inching Circuit Installation, with View of Inching Actuator 4. Inching  circuit  bleeder  screw  is  installed  in  the end    of    inching    actuator    (slave    cylinder)    on control  valve  on  transaxle,  adjacent  to  inching control line.  See Figure 2. NOTE Inching    actuator    housing    is    designed    to    be adjustable  for  positioning  the  bleeder  screw  at the   top,   using   the   adjusting   nut.      To   adjust, loosen   adjusting   nut,   rotate   actuator   to   place bleeder  screw  at  top,  then  tighten  nut  to  lock actuator in place. Pressure Bleeding Procedure "Bottom Up" Bleeding With Pressure Bleeder 1. Inching bleeder screw closed. 2. Brake bleeder screws closed. 3. Remove cap from brake fluid reservoir. 4. Connect   inching   filler   hose   to   inching   bleeder screw and open bleeder screw. 5. Wait until brake fluid reservoir is 50% full. 6. Pump   inching   (left)   pedal   5-10   strokes   (with quick   return   strokes   and   1-2   second   intervals between strokes) while filling. 7. Tighten  inching  bleeder  screw  after  reservoir  is 75% full. 8. Install    brake    filler    hose    on    right-side    brake bleeder screw. 9. Install   brake   drain   overflow   hose   on   left-side brake bleeder screw. 10. Loosen both brake bleeder screws. 11. Fill   brake   lines   (fluid   will   drain   from   reservoir after Step 10 until Step 11 is started). 12. Wait   until   a   steady   flow   is   achieved   from   left brake bleed drain line with no air bubbles. 13. Close left-side brake bleeder screw. 14. Wait until reservoir fluid level starts to rise. 15. Stroke  brake  (right)  pedal  5-10  times  with  quick return strokes and 1-2 second intervals between strokes. 16. Close right-side brake bleeder screw. 17. Remove filler hoses. 18. Install cap on brake fluid reservoir. F-397
