At your car brake shoes too quickly wear out? There was a palpation of brake disks? Do not hurry to accuse of all of a brake. Often in strangers, at first sight, the phenomena it is necessary to look for the true reasons of failure of details of brake systems.
Wheel and tire
Kolebo assembled should be faultlessly otbalansirovano. Be convinced that there is no radial and face palpation as rims, and tires. Wheel bolts should be tightened only with the ordered moment and in the correct sequence (evenly and perekrestno).
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, the directing planes) should be faultless. Established new blocks should possess good mobility in directing a support and fastening.
Use only original brake shoes of the ATE brand (or another, allowed to application). Select them precisely according to type of the car and year of its manufacturing. Needlessly do not allow sharp braking the first 200 km after replacement of blocks to provide with it soft "running in grinding in".
To change brake disks follows at the same time on all axis, having taken new it is obligatory from one packing. By means of suitable solvent completely remove from a disk anticorrosive protection. Surfaces of flanges and centering openings should be pure, without agnails and damages. Do not forget that at ventilated disks it is necessary to consider the rotation directions, and it is impossible to delete balancing brackets. Centering should be made strictly observing the ordered moment and the correct sequence of an inhaling. Replacing brake disks, surely change also blocks. At emergence of difficulties прифланцуйте disks with the ordered moment of an inhaling also check face palpation by means of the strelochny indicator at distance of 10 mm from external edge of a frictional surface. If palpation too strong, whenever possible move a disk step by step to other provisions, again checking palpation.
The site for a flange and an aligning opening should be smoothed out a nazhdachny cloth before emergence of metal shine. On them should not remain neither rusts, nor dirt. They should not be warped and damaged. It is not necessary to put greasing pastes (including copper). Check a site for a flange and an aligning opening on absence of palpation and on the plane. Consider that palpation of a nave involves twice bigger palpation of disks. Priflantsovyvy a brake disk, observe the recommended moment and the correct sequence of an inhaling.
Wheel suspension bracket
Levers of an independent suspension bracket should not be deformed, and saylent-blocks – soft and broken. In safety there should be rubber plugs of shock-absorbers, and shock-absorbers (or are resistant) – in a faultless working condition. Check, that corners of installation of wheels in accuracy corresponded to manufacturer requirements.
Bearings of wheels
Check degree of wear of bearings. Establish, fix and adjust them according to the manufacturer instruction.
Check steering details on wear. Heads of steering drafts should not be broken, and drafts – deformed. The steering shock-absorber (if it is present on your car) should be in a faultless working condition.
