Replacement

PERFORMANCE ORDER
1) disconnect a wire of the negative plug of the accumulator
2) disconnect brake hoses
3) remove the hydraulic pump

The prevention

At removal and installation of brake hoses, check up, that they have been designated and established according to marks in the hydraulic pump.


Establish only firm brake hoses.

At repair, close brake hoses and branch pipes as soon as possible.

The moment of an inhaling of fastenings of brake hoses 15 Н.м.

At work which demand depressurization of hydraulic system, merge a brake liquid by means of the device for filling / of draining of a brake liquid.

In addition, it is necessary to inspect high and low pressure in brake system.

High and low pressure, check

PERFORMANCE ORDER
1) unscrew the screw спускного apertures of a support of a forward brake;
2) connect tool VW 1310 and pump over brake system;
3) establish the press device of a brake pedal between a pedal of a brake and sitting of the driver
4) press on a brake pedal that the pressure indicator showed 50 Bar
5) observe of indications of the gauge within 45 seconds
6) pressure should not fall more, than to 4 Bars
7) if pressure has fallen on большее value, replace the hydraulic pump
8) adjust the press device of a pedal of a brake so that the pressure indicator in brake system showed pressure in 6 Bar
9) wait for 3 minutes

10) pressure should not fall more, than to 1 Bar

11) if pressure has fallen on большее value, replace the hydraulic pump
