Removal, major maintenance and installation of a support of the disk brake mechanism

The dust developed by brake mechanisms in the course of their work can contain unhealthy asbestos. At all do not blow off a dust from surfaces of components of brake mechanisms the compressed air and do not inhale it. Works are best of all for making in a protective respiratory mask. At all do not use for cleaning of components of brake mechanisms solvents on an oil basis or gasolines - use only patent means for cleaning of brakes!


If there is a need for carrying out major maintenance of a support (usually in a consequence of existence of leakages of liquid), before starting to work study all possible options of its performance. It is possible to get on an exchange basis fabrichno the restored supports that considerably simplifies a task. If the decision on restoration of an old support is made before beginning work make sure available a special remnabor. Supports always are under repair in pairs - carrying out major maintenance only one of them is not admissible at all!

Removal

 PERFORMANCE ORDER

  1. Uncover the tank of brake liquid. Suck away (not a mouth) from the tank two thirds of its contents. Merge liquid in the container for the subsequent delivery it in special place of acceptance.
  2. Weaken nuts of fastening of forward wheels, поддомкратьте a front of the car and establish it on props. Remove forward wheels.
  3. Drown the support piston in the nest (see a picture).

If are going to remove only a support (and not to make its major maintenance), do not disconnect from it a brake hose. Give a hollow bolt of reception shtutserny knot of a brake hose and disconnect a hose from a support (see an illustration). Near at hand it is necessary to have rags for collecting spilled liquid. Wrap up the hose end a polyethylene film and fix it a rubber bandage (or закупорьте a hose) in order to avoid excessive losses of liquid and hit in dirt system.

  1. Give two fixing bolts remove a support from the car (The section Replacement of blocks of disk brake mechanisms). If the support acts in film for the purpose of ensuring access to other components, tie up it aside to a suspension bracket element - watch, that the brake hose thus did not stretch!

Major maintenance

 PERFORMANCE ORDER

  1. Wipe an external surface of a support a special cleaner or pure brake liquid. At all do not use gasoline, kerosene or solvents on an oil basis! Lay a support on a pure workbench.
  2. Enclose in a support as a pillow wooden whetstone or some lumps of rags and squeeze out the piston of the support cylinder the compressed air. It is not necessary to increase supply of air more than it is necessary for piston squeezing. At too strong pressure the piston, having jumped out it can be damaged, without watching at all at the enclosed pillow.

At all do not thrust fingers into space in front of the piston when blowing last of the cylinder is it is fraught with receiving a serious trauma.


  1. Having enclosed under an obverse surface of the piston of a support an amortization pillow (wooden whetstone or rags), squeeze out the piston of the cylinder the compressed air - watch that fingers did not get between the piston and a support frame (pillow)!
  1. Carefully take a boot from a support nest.
  1. Carefully take a boot from a support.

Components of a support of the disk brake mechanism.

  1. By means of the wooden or plastic tool take a cuff from a flute in a support nest Use of metal tools can lead to damage of a mirror of a nest.
  1. The cuff of the piston should be taken from a nest by means of the wooden or plastic tool in order to avoid damage of a mirror of a nest and/or a cuff flute - it is convenient to use for this purpose a pencil.
  1. Turn out the gate of pumping of a support, then remove and throw out plugs of fixing pins. Remember that rubber components are not subject to the repeated use.
  1. Grasp edges of plugs under installation of fixing pins by nippers and, making rotary progress by a hand, take them from support eyes.
  1. Wash out the remained components in a patent cleaner or pure brake liquid, then dry them the compressed air.
  2. Carefully check the piston on existence задиров, agnails or violations of an external covering. In case of detection of defects of a surface the component is subject to replacement.
  3. To similar check subject a mirror of a nest of the piston in a support. Insignificant defects can be eliminated by means of polishing by a thin emery paper. The fixing pins of a support defective or damaged by corrosion are subject to replacement.

Installation

 PERFORMANCE ORDER

  1. At assembly grease a mirror of a nest and a cuff of the piston with pure brake liquid. Establish a cuff in a flute in a nest.
  2. Grease the piston with pure brake liquid, then fill it perpendicularly and knock down against the stop in a nest bottom.
  1. At piston installation a support before утапливать it in a nest make sure that it is not warped.
  1. Fill a new boot in a flute on the piston, then accurately plant it in a nest.
  1. If there is no possibility of use of the special tool for boot landing in a support nest, it is possible accurately обстучать it on all perimeter a drift.
  1. Screw the pumping gate.
  2. Establish internal and external plugs of pins of fastening of a support
  3. Check fixing pins on existence of signs of excessive corrosion, in case of need make replacement.
  4. Clear and grease plugs of fixing pins of a support (see illustrations "Take plugs of both fixing pins..." and "Establish plugs into place").
  5. Establish a support.
  6. Connect a brake hose and tighten a hollow bolt of its fastening to a support, having laid new copper washers. Tighten a bolt with demanded effort.
  7. If the brake line undocked, do not forget to pump over a brake (The section Pumping of brake system).
  8. Establish wheels and lower the car on the earth. Tighten nuts of fastening of wheels with demanded effort.
  9. On termination of work several times strongly squeeze out a brake pedal for a usadka of blocks on a disk.
  10. Before starting operation of the car check serviceability of functioning of brakes.
