Condition check, removal and installation of brake disks

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

Disks of forward brake mechanisms

Condition check

 PERFORMANCE ORDER

1. Prop up противооткатными boots back wheels, поддомкратьте redock of the car and establish it on props. Remove a corresponding forward wheel.
2. Slowly rotating a disk, attentively examine it from both parties. In case of need remove brake Pads for the purpose of maintenance of the best review of an inside of a disk (Replacement колодок disk brake mechanisms of forward wheels see). Presence of small scratches on workers contacting with колодками disk surfaces is quite admissible, however, in case of revealing 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 disk perimetre the fillet formed as a result of development of a material settles down, it is necessary to make measurement of a thickness of a disk by means of a micrometer. The size acts in film in several points on perimetre of a disk both in area of contact with колодками, and out of it. The disk worn out over an admissible limit (Specifications see) is subject to replacement.

4. In the presence of suspicions on deformation presence it is necessary to make check of lateral palpation of a disk. Take advantage циферблатным of a measuring instrument плунжерного type which should be fixed on a motionless component of a suspension bracket, or with the help probeа лезвийного type measure backlash size between a disk and the motionless object located to it closely (for example, анкерной скобой a support). The size acts in film in several points on disk perimetre. In case of revealing of palpation exceeding admissible value (Specifications see), the disk is subject to replacement (preliminary make sure that the palpation reason is not deterioration or pretightness easing ступичных bearings [Routine maintenance or the Running gear and a steering] see the Head). Try to remove also a disk and to turn it on a nave on 180 .

5. Examine a disk on presence of cracks around болтовых apertures and other signs of deterioration or mechanical damages. In case of need make replacement.

Removal

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
2. Remove brake Pads (Replacement колодок disk brake mechanisms of forward wheels see).
3. Turn out two bolts of fastening анкерной скобы a support on ступичной to assemblage. Clean a support aside and tie up its wire to a suspension bracket element. Track, that it has not appeared will pull a brake hose.

4. Turn out two fixing screws and remove a disk with ступичной assemblages.

Installation

 PERFORMANCE ORDER

1. Make sure of absoluteness of cleanliness of interfaced surfaces of a brake disk and ступичной assemblages, 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 Pads (Replacement колодок disk brake mechanisms of forward wheels see) and connect a negative wire to the battery.

Disks of back brake mechanisms

Condition check

 PERFORMANCE ORDER

1. Cock a lay brake, prop up противооткатными 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 колодок disk brake mechanisms of back wheels has undressed.

Removal

 PERFORMANCE ORDER

1. Поддомкратьте the car also establish it on props.
2. Remove a corresponding back wheel.
3. Dump pressure in a hydraulic path of a suspension bracket, having released спускной the regulator gate (the Uniform hydraulic system see the Head) and having translated a control lever in position "Minimum".
4. Remove brake Pads (Replacement колодок disk brake mechanisms of back wheels see).
5. Fill on the regular place a fastening finger колодок and screw on it a nut, having fastened thereby among themselves two half of 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 an element of a suspension bracket by means of a wire. Track, that it has not appeared 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 cleanliness 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 into place and tighten bolts with demanded effort.
4. Give a fixing nut and take a fastening finger колодок, fixing among themselves half of support.
5. Establish into place Pads (Replacement колодок disk brake mechanisms of back wheels see).
6. Establish a wheel.
7. Tighten спускной the gate of a regulator of pressure (the Uniform hydraulic system see the Head) and translate a control lever a suspension bracket in position “Normal driving” (Normal movement).
8. Lower the car on the earth and tighten wheel bolts with demanded effort.
