Condition check, removal and installation of a brake disk

Condition check

 PERFORMANCE ORDER

    Loosen the nuts of fastening of a wheel, поддомкратьте redock of the car also establish it on props. Remove a wheel. Remove a brake support (Has undressed Removal, major repairs and installation of a support of the disk brake mechanism). Now there is no necessity to disconnect from a support a brake hose (see an illustration). Tie up a support to an element of a suspension bracket by means of a wire piece. Do not suppose a tension and перекручивания a brake hose. On pair hairpins of fastening of a wheel fixing washers should be already established. If is not present, screw on two of them nuts of fastening of a wheel for disk fixing. Check up a disk surface on presence of scratches, furrows and other damages. Presence of small scratches and superficial furrows is the normal phenomenon for the disk which was in the use does not render appreciable influence on efficiency of braking, however, furrows depth over 0,38 mm demand removal of a disk and its carrying out станочной processing in the conditions of a car-care centre workshop. Do not forget to examine a disk from both parties. If at braking pedal pulsations are felt, it can be a consequence of disk palpation. Check up also correctness of adjustment of bearings of wheels. For check of size of palpation of a disk fix циферблатный the indicator плунжерного type approximately in 13 mm from external edge of a disk and having pressed плунжер to a disk surface. Null the device and start to rotate a disk. Indicator indications should not exceed an admissible limit of palpation. Otherwise the disk is subject проточке in a car-care centre workshop.

Composers of the given Management recommend to make проточку a disk in independence of measuring instrument indications (for the purpose of restoration of its surfaces for decrease in pulsations and other undesirable phenomena at the braking, directly connected with a disk condition). As a last resort, disk surfaces can be processed simply at least an emery paper, having removed from them polishing traces (making the rotary motions guaranteeing absence of directed traces from an abrasive on the processed surface).


    Define size of palpation of a disk with the help циферблатного a measuring instrument плунжерного type - instrument readings should not exceed admissible under Specifications of a limit of palpation - otherwise the disk is subject проточке or replacement.
    By means of rotary motions remove traces of polishing from surfaces of a disk an emery paper.
    Проточка a disk it should be made taking into account admissible its minimum thickness (usually on an internal surface of a disk there are corresponding marks). The thickness of a disk can be defined by means of a micrometer. If marks are absent, address to Specifications to the given Chapter.
    The minimum admissible thickness of a brake disk can be beaten out (or is poured out) on its inside.
    Measure a thickness of a disk in several points by means of a micrometer.

Removal

 PERFORMANCE ORDER

    Remove two wheel nuts, established for disk fixing, then remove a disk from a nave. If the disk is fixed special, напрессованными on hairpins by washers, cut off their diagonal кусачками and throw out.
    If the disk is fixed on a nave by two special washers, cut off their diagonal кусачками and throw out.

Installation

 PERFORMANCE ORDER

    Put on a disk the place on hairpins of fastening of a wheel. Establish assemblage of a support with brake колодками (Has undressed Removal, major repairs and installation of a support of the disk brake mechanism). Tighten bolts of fastening of a support with demanded effort. Establish into place a wheel and lower the car on the earth. Tighten nuts of fastening of a wheel with demanded effort. Some times squeeze out brake for усадки колодок on a disk. Prorolling of brake system to make there is no necessity if certainly brake hose was not disconnected from a support. Before starting car operation check up serviceability of functioning of brake system.
