Repair and operation of the car

At your car brake shoes too quickly wear out? There was a beating of brake disks? You do not hurry to accuse of all brakes. 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

By Kolebo it has to be assembled faultlessly balanced. Make sure that there is no radial and face beating both rims, and tires. Wheel bolts should be tightened only with the ordered moment and in the correct sequence (evenly and cross).

Brake mechanisms

Be convinced of a good general shape of brake systems. Protective caps should not have damages. The course of pistons, in perfect tune – the directing elements (directing the plugs directing the bolts sending to the plane) has to be faultless. The established new blocks have to have good mobility in guides of a support and fastening.

Brake shoes

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 production. Needlessly do not allow sharp braking the first 200 km after replacement of blocks to provide them soft "running in grinding in".

Brake disks

It is necessary to change brake disks at the same time on all axis, having taken new it is obligatory from one packing. By means of suitable solvent completely remove anticorrosive protection from a disk. Surfaces of flanges and centering openings have to be pure, without agnails and damages. Do not forget that at the ventilated disks it is necessary to consider the directions of rotation, 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 to a priflantsuyta disks with the ordered inhaling moment also check a face beating by means of the arrow indicator at distance of 10 mm from the outer edge of a frictional surface. If a beating too strong, then whenever possible move a disk step by step to other provisions, again checking a beating.

Wheel nave

The site for a flange and the aligning opening should be smoothed out an emery cloth before emergence of metal gloss. On them there should not be neither rust, nor dirt. They should not be warped and damaged. It is not necessary to put greasing pastes (including copper). Check the site for a flange and the aligning opening for lack of a beating and for the plane. Consider that the beating of a nave involves twice a bigger beating 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 have to be rubber plugs of shock-absorbers, and shock-absorbers (or are resistant) – in the faultless working condition. Check that the angles of installation of wheels in accuracy conformed to requirements of manufacturer.

Bearings of wheels

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

Steering

Check steering details for wear. Heads of steering drafts should not be broken, and drafts – deformed. The steering shock-absorber (if it is present at your car) has to be in the faultless working condition.
