Condition check, removal and installation of brake disks

Attentively read the preventions given at the beginning of sections Replacement of blocks of disk brake mechanisms of forward wheels and Replacement of blocks of disk brake mechanisms of back wheels. Replacement of disks is always made in pair for both brake mechanisms of this axis in order to avoid loss of course stability of the car when braking.

Disks of forward brake mechanisms

Condition check

 PERFORMANCE ORDER

1. Prop up protivootkatny boots back wheels, поддомкратьте a front of the car and establish it on props. Remove the corresponding forward wheel.
2. Slowly rotating a disk, attentively examine it from both parties. In case of need remove brake shoes for the purpose of providing the best review of inside of a disk (see. Replacement of blocks of disk brake mechanisms of forward wheels). Existence of small scratches on workers surfaces of a disk contacting to blocks is quite admissible, however, in case of identification of deep furrows, задиров and other serious defects the disk is subject to replacement.

3. On external edge of surfaces of a disk usually there passes the covered strip beaten by a corrosion brake dust which can be in case of need smoothed out by means of a scraper. If on perimeter of a disk the fillet formed as a result of development of a material settles down, it is necessary to make measurement of thickness of a disk by means of a micrometer. The size acts in film in several points on perimeter of a disk both in area of contact to blocks, and out of it. The disk worn out over an admissible limit (see. To the specification) is subject to replacement.

4. In the presence of suspicions on existence of deformation it is necessary to make check of lateral palpation of a disk. Use a tsiferblatny measuring instrument of plunzherny type which should be fixed on a motionless component of a suspension bracket, or with the help щупа lezviyny type measure gap size between a disk and the motionless object located to it closely (for example, an anchor bracket of a support). The size acts in film in several points on disk perimeter. In case of identification of palpation exceeding admissible value (see. Specifications), the disk is subject to replacement (previously make sure that the reason of palpation is not wear or weakening of a pretightness of stupichny bearings [see. Head Routine maintenance or Running gear and steering]). Try to remove also a disk and to overturn it on a nave on 180 °.

5. Examine a disk on existence of cracks round boltovy openings and other signs of wear or mechanical damages. In case of need make replacement.

Removal

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
2. Remove brake shoes (see. Replacement of blocks of disk brake mechanisms of forward wheels).
3. Turn out two bolts of fastening of an anchor bracket of a support on stupichny assembly. Clean a support aside and tie up it a wire to a suspension bracket element. Track, that it did not appear will pull a brake hose.

4. Turn out two fixing screws and remove a disk from stupichny assembly.

Installation

 PERFORMANCE ORDER

1. Make sure of absoluteness of purity of interfaced surfaces of a brake disk and stupichny assembly, then establish a disk on the regular place. Also tighten fixing screws.
2. Establish into place a support and tighten bolts of its fastening with demanded effort.
3. Establish brake shoes (see. Replacement of blocks of disk brake mechanisms of forward wheels) also connect a negative wire to the battery.

Disks of back brake mechanisms

Condition check

 PERFORMANCE ORDER

1. Cock the parking brake, prop up protivootkatny boots forward wheels, then поддомкратьте a back of the car and establish it on props.
2. Execute the procedures described in subsection "Condition check", addressing in case of need to materials Replacement of blocks of disk brake mechanisms of back wheels undressed.

Removal

 PERFORMANCE ORDER

1. To Poddomkratta the car also establish it on props.
2. Remove the corresponding back wheel.
3. Dump pressure in a hydraulic path of a suspension bracket, having released spuskny the regulator gate (see. Head Uniform hydraulic system) and having transferred a control lever to the situation "Minimum".
4. Remove brake shoes (see. Replacement of blocks of disk brake mechanisms of back wheels).
5. Fill on the regular place a finger of fastening of blocks and screw on it a nut, having fastened thereby among themselves two half of a support.
6. Turn out two bolts of fastening of a brake support to the longitudinal lever of a suspension bracket.
7. Remove a support from a brake disk and tie up it aside to a suspension bracket element by means of a wire. Track, that it did not appear the brake line is tense.

At desire the support can be fixed by means of the top bolt after disk removal.

8. Turn out the fixing screw and remove a disk from a wheel nave.

Installation

 PERFORMANCE ORDER

1. Where it is required, turn out the top bolt and shift a support aside, having provided free space for disk installation.
2. Make sure of absoluteness of purity of interfaced surfaces of a disk and a nave. Establish a disk on the regular place and tighten the fixing screw.
3. Grease a carving part of fixing bolts, then establish a support on a place and tighten bolts with demanded effort.
4. Give a fixing nut and take a finger of fastening of the blocks, fixing among themselves support half.
5. Establish to the place of a block (see. Replacement of blocks of disk brake mechanisms of back wheels).
6. Establish a wheel.
7. Tighten spuskny the gate of a regulator of pressure (see. Head Uniform hydraulic system) also transfer a control lever a suspension bracket to the situation "Normal driving" (Normal movement).
8. Lower the car on the earth and tighten wheel bolts with demanded effort.
