Replacement of a cable of the hand brake

 PERFORMANCE ORDER

  1. Lift and fix a back part of the car.
  2. Weaken the hand brake.
  3. Dismantle the heat-shielding screen of system of an exhaust in the field of directing a cable of the hand brake.
  4. For this purpose there can be necessary a dismantle of a part of system of an exhaust.
  5. Weaken a cable of the hand brake on the adjusting device, for this purpose take out fixing collar of an adjusting element and against the stop screw up an adjusting nut.
  6. On the end of a cover of a cable on a brake support wring out a spring bracket and remove a nipple of a brake cable from a control lever.
  7. Only in quattro!: take out a cable of the hand brake from a back axis directing at height. Compress for this purpose a sleeve of the directing.
  8. Now take out a cable from various arms on a back axis and on the bottom of the car and remove it.
  9. At height of the lever of the hand brake under the bottom of the car wring out a cover of a cable of the hand brake from the console (use a screw-driver).
  10. Dismantle a back part of the average console in salon (head Salon).
  11. Take out from a yoke cables on the lever of the hand brake.
  12. Remove brake cables down.
  13. Installation of new brake cables: on a yoke of the hand brake remove the inserted plastic details if they are (any more do not put them).
  14. Screw-driver fix a yoke on the average situation.

  6. Weaken a cable of the hand brake in the adjusting mechanism, take out for this purpose fixing collar of the adjusting mechanism and screw up against the stop an adjusting nut.
  7. Shift the device of rough adjustment in the adjusting mechanism.
  8. Now screw up an adjusting nut of the adjusting mechanism until there is visible a groove of a fixing collar.
  9. Again insert fixing collar.
  10. Evenly stretch in different directions the device of rough adjustment on both covers of brake cables so that brake cables were tense, but the control lever did not rise yet from an emphasis on a brake support.
