Removal, regenerative repair and installation of supports of disk brake mechanisms of back wheels

Remember that developed in the course of operation of brake mechanisms the dust can contain extremely unhealthy the person asbestos. At all do not blow off a dust the compressed air and do not inhale it, - at service of mechanisms put on a protective mask or a respirator. At all do not use for rubbing of components of brake system by gasoline or solvents on an oil basis, - apply only firm cleaners or methyl alcohol!


Supports of both brake mechanisms of one axis should change at the same time.

Removal

 PERFORMANCE ORDER

  1. Prop up forward wheels protivootkatny boots, поддомкратьте a back of the car and establish it on props, remove the corresponding back wheel.
  2. Completely lower the lever of the parking brake and release an adjusting nut for the purpose of weakening of a driving cable.
  3. Screw-driver wring out the executive lever of the parking brake behind a support of the brake mechanism of a back wheel and disconnect from it a driving cable. Release a lock nut and liberate a cable cover from a basic arm on remove.
  4. Uncover the GTTs tank put under it a polyethylene film and screw on a place, - the podkladyvaniye of a film pressurizes landing of a cover and will prevent a liquid effluence at an otpuskaniye of shtutserny connection of a flexible brake hose. Alternatively the hose can be pressed by a suitable clamp.
  5. Carefully wipe shtutserny connection of a hose on a support. Turn out a hollow bolt of the socket and remove copper sealing washers, - washers are subject to replacement without fail. At once закупорьте the open end of a hose and the union in order to avoid hit in dirt system.
  6. Remove brake shoes (see. Replacement of blocks of disk brake mechanisms of back wheels). Remove a support from the top directing bearing.
  1. In case of need turn out a bolt of fastening (3) anchor brackets (4) supports to the bottom lever of a suspension bracket.

Repair

The back support is not subject to regenerative repair and in case of failure is replaced assembled.

 PERFORMANCE ORDER

  1. Remove from an anchor bracket the bottom directing rack and carefully it wipe. In case of identification of signs of excessive wear replace a rack, - before installation it is necessary to grease a rack with silicone greasing.
  2. If the support is equipped dempfiruyushchiya gruziky, disconnect a spring and turn out a bolt of fastening of a cable of the parking brake. Transfer the corresponding details on a new support and tighten a fixing bolt with demanded effort, previously having greased its carving with fixing hermetic.

Installation

 PERFORMANCE ORDER

  1. If removed, establish an anchor bracket of a support on the suspension bracket lever. Screw fixing bolts and tighten them with demanded effort, - before installation it is necessary to grease a carving part of bolts with fixing hermetic.
  2. Clear the top directing rack of a support and grease it with silicone greasing. Plant a support on a rack and establish brake shoes (see. Replacement of blocks of disk brake mechanisms of back wheels).
  3. Having replaced sealing washers, connect to a support a flexible brake hose. Make sure of correctness of landing of a hose in support dredging, then tighten a shtutserny bolt with demanded effort.
  4. Remove a clamp pressing a hose, or or remove polyethylene from under a cover of the GTTs tank and pump over brake system (see. Pumping of brake system).

It is enough to pump over only that contour which support acted in film.
