14.37. Malfunctions of brake system

At your car too quickly wear out brake колодки? There was a palpation of brake disks? Do not hasten to accuse in all a brake. Often in strangers, at first sight, the phenomena it is necessary to search for the true reasons of failure of details of brake systems.

Wheel and the tyre

Колебо in gathering it should be faultless отбалансировано. Be convinced that there is no radial and face palpation as rims, and tyres. Wheel bolts should be tightened only with the ordered moment and in correct sequence (in regular intervals and перекрестно).

Brake mechanisms

Be convinced of a good general condition of brake systems. Protective caps should not have damages. The course of pistons, in perfect tune – directing elements (the directing plugs directing bolts, directing planes) should be faultless. Established new колодки should possess good mobility in a directing support and fastening.

Brake колодки

Use only original brake колодки marks ATE (or another, admitted to application). Select them precisely according to type of the car and year of its manufacturing. Needlessly do not suppose sharp braking the first 200 km after replacement колодок to provide with it soft "obkatku-grinding in".

Brake disks

To change brake disks follows simultaneously on all axis, taking new necessarily from one packing. By means of suitable solvent completely remove from a disk anticorrosive protection. Surfaces of flanges and centering apertures should be pure, without agnails and damages. Do not forget that at ventilated disks it is necessary to consider rotation directions, and it is impossible to delete balancing скобы. Centering should be made strictly observing the ordered moment and correct sequence of an inhaling. Replacing brake disks, necessarily change and колодки. At occurrence of difficulties прифланцуйте disks with the ordered moment of an inhaling also check up face palpation with the help стрелочного the indicator on distance of 10 mm from external edge of a frictional surface. If palpation too strong whenever possible move a disk stage by stage to other positions, again checking palpation.

Wheel nave

The site for a flange and an aligning aperture should be smoothed out наждачным a cloth before occurrence of metal shine. On them should not remain neither rusts, nor a dirt. They should not be warped and damaged. It is not necessary to put greasing pastes (including copper). Check up a site for a flange and an aligning aperture on absence of palpation and on a plane. Consider that nave palpation involves twice большее palpation of disks. Прифланцовывая a brake disk, observe the recommended moment and correct sequence of an inhaling.

Wheel suspension bracket

Levers of an independent suspension bracket should not be deformed, and sajlent-blocks – soft and broken. In safety there should be rubber plugs of shock-absorbers, and shock-absorbers (or racks) – in a faultless working condition. Check up, that corners of installation of wheels in accuracy corresponded to manufacturer requirements.

Bearings of wheels

Check up degree of deterioration of bearings. Establish, fix and adjust them according to the manufacturer instruction.


Check up steering details on deterioration. Heads of steering draughts should not be broken, and draughts – deformed. The steering shock-absorber (if it is present on your car) should be in a faultless working condition.
