Prevention
Replacement At repair, close brake hoses and branch pipes as soon as possible. Moment of an inhaling of fastenings of brake hoses of 15 N. of m. At work which demand depressurization of hydraulic system merge brake fluid by means of the device for filling / draining of brake fluid. In addition, it is necessary to carry out an inspection of high and low pressure in the brake system. High and low pressure, check 10) pressure should not drop more, than by 1 Bar

PERFORMANCE ORDER
1) disconnect a wire of the negative plug of the accumulator
2) disconnect brake hoses
3) remove the hydraulic pump
Prevention
Establish only company brake hoses.
PERFORMANCE ORDER
1) unscrew the screw of a spuskny opening of a support of a forward brake;
2) connect the VW 1310 tool and pump over the brake system;
3) install 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 indicator of pressure showed 50 Bars
5) watch indications of the sensor within 45 seconds
6) pressure should not fall more, than on 4 Bara
7) if pressure fell to bigger value, replace the hydraulic pump
8) adjust the press device of a pedal of a brake so that pressure indicator in the brake system showed pressure in 6 Bars
9) wait 3 minutes
11) if pressure fell to bigger value, replace the hydraulic pump
