Check of a condition of brake mechanisms (each 12 000 km (7500 miles) run, or times in 6 months)

Detailed illustrations of an arrangement of components of brake mechanisms are given in Head Brake system.


The dust developed in brake mechanisms can contain unhealthy asbestos. At all do not blow off a brake dust the compressed air and try not to inhale it. At works on repair and service of brake mechanisms use a special filtering mask or a respirator. Under no circumstances do not apply to cleaning of components of brake mechanisms solvents on an oil basis. For this purpose only the special cleaning structure or the denatured alcohol should be used!

In addition to stipulated by the schedule of routine maintenance of the car to review periods of brake system, the condition of brake mechanisms should be checked each time at removal of wheels or at manifestation of signs of malfunction of brakes.

For check of a condition of components of brake mechanisms the car should be lifted over the earth and is established on props. Remove wheels (see. Poddomkrachivaniye and towage at the beginning of the Management) undressed.

Disk brake mechanisms

Disk brake mechanisms usually equip forward wheels of the car, but in certain cases - and back. Wear of brake shoes over the limits stipulated in Specifications can lead to irreversible damage of brake disks.

Supports of disk brake mechanisms in which blocks are established, after removal of wheels become well visible. In each support there is one external brake shoe and one internal. The condition of all four blocks should be checked.

Each support is equipped with an observation port or an opening through which the condition of blocks can be checked. The thickness of overlays of blocks should be checked by a zaglyadyvaniye in a support from each of its end faces, and also through the top observation port. If the material of blocks is worn-out below an admissible limit (lower than 7,9 mm), all set of blocks is subject to replacement.

Blocks of disk brake mechanisms can be examined through specially provided in the support case an opening - for carrying out measurement put to an observation port a ruler.


 PERFORMANCE ORDER

  1. If you meet difficulties with determination of thickness of the remained frictional material, remove blocks for more detailed research (Head Brake system).
  2. Before installation of wheels into place make sure of absence of leakages of brake liquid and/or damages of brake hoses (cracks, splittings, etc.) in the area their connection to unions of supports. In case of need replace hoses (or unions) (Head Brake system).
  3. Check a condition of brake disks. In case of detection of deep scratches, furrows and overheat traces, nave assembly with a disk is necessary for removing for carrying out recovery operations (Head Brake system).

Drum-type brake mechanisms

 PERFORMANCE ORDER

  1. On back brake mechanisms remove drums, having pulled together them from pins of driving shaft/semi-axes and brake assemblies. If the drum does not give in to removal, make sure that the parking brake is released, then moisten with getting oil a joint between a nave and a drum and repeat attempt to remove a drum.
  2. If the drum on the former does not give in to removal, it is necessary to "release" the self-regulator mechanism slightly. For this purpose at first it is necessary to take a small stopper from a board of the brake mechanism.
  3. Having removed a stopper, insert into an opening a thin screw-driver and raise the regulator lever, having taken away it from a gear castor, then by means of the special adjusting tool or besides a screw-driver turn a castor back on some turns. It will lead to an otodviganiye of brake boots from drum walls. If the drum does not act in film and now, обстучите it from within on all perimeter a hammer with soft the brisk.
  1. Thin screw-driver raise the regulator lever, then the special tool or other screw-driver turn the released gear castor back on some turns.
  1. Having removed a drum, watch to touching a brake dust (see the prevention at the beginning of the Section).
  2. Check thickness and a condition of frictional slips both (forward and back) brake boots. If the material of slips is worn-out below an admissible limit (1.6 mm), boots should be replaced. Boots are subject to replacement as well in case of detection in them of cracks or existence zapolirovanny to shine or polluted by oil / brake liquid of sites of slips.
  1. If slips are pasted on boots, measurement of their thickness is made from the upper edge of a metal substrate to external edge of a slip, as is shown in drawing if a slip приклепана, measurement is made from external edge of a slip to a surface of heads of rivets.
  1. Make sure that all springs of the brake mechanism are connected and are in a satisfactory condition.
  2. Check components of the brake mechanism on existence of traces of leakages of brake liquid. Carefully hook rubber boots of the wheel cylinders located in the top part of boots. Existence of any signs of leaks demands immediate carrying out major maintenance of wheel cylinders (Head Brake system). Check also on existence of signs of leaks brake hoses and their shtutserny connections.
  1. For check of a condition of the wheel cylinder by a small screw-driver carefully hook a rubber boot of the cylinder.
  1. Wipe an internal surface of a drum the pure rags moistened with a special cleaner or methyl alcohol. Remember that asbestos is very unhealthy - do not inhale a brake dust!
  2. Check an internal surface of a drum on existence of cracks, cavities, deep scratches and sites of an overheat which are appreciable by change of coloring of a surface. If defects cannot be eliminated by means of a thin emery paper, it is necessary to deliver a drum in a car-care center workshop for a pro-point.
  3. If during check all components are found in a satisfactory condition, establish a drum into place.
  4. Establish wheels and lower the car on the earth.

Parking brake

Management of the parking brake is carried out manually, by means of the lever. The parking brake influences brake mechanisms of back wheels. The simplest and most evident way of check of serviceability of functioning of the parking brake is the car stop on the inclined plane. If after control lever raising by the parking brake the car does not keep on a bias motionlessly, the brake needs adjustment (Head Brake system).
