Check of serviceability of functioning, removal and installation of the valve-regulator of pressure in hydraulic contours of brake mechanisms of back wheels

The material of the given Section concerns only models without ABS.

CHECK

 PERFORMANCE ORDER

1. On not equipped ABS models the hydraulic contour of each of back brake mechanisms is equipped by the pressure valve-regulator that allows to avoid premature blocking of back wheels of the car at sharp braking. Depending on a model complete set can be used or one sensitive to degree of loading of the car the valve-regulator, or two hydraulic pressure of the valve sensitive to change.
2.Чувствительные to change of pressure in a path valves-regulators are rolled directly target unions of back brakes ГТЦ. Design ГТЦ provides independent functioning of two hydraulic contours - primary and secondary, each of which influences one forward and one (диагонально located) back wheels. Valves-regulators operate as the terminators which are not allowing hydraulic pressure influencing back brake mechanisms to rise above a certain limit. At such scheme the brake effort developed by forward wheels always more than developed back.
3. Unique sensitive to degree of loading of the car the valve-regulator is established on the car bottom, in its back part and a special spring is connected to the bridge of a back suspension bracket. On size of displacement of the bridge concerning the bottom the valve defines level of weight loading having on back wheels and accordingly corrects size of the maximum admissible hydraulic pressure developed in back brake contours.
4. Check of serviceability of functioning of valves of regulators is made by means of the special diagnostic equipment and for its carrying out the car should be driven away on a car repair shop. Regenerative repair of the failed valves-regulators is not obviously possible, that is why defective components are subject to replacement in gathering.

REMOVAL

 PERFORMANCE ORDER

Before to start procedure performance, familiarise with the prevention text in the beginning the system Design, the description of separate knots and mechanisms Has undressed.

1. For the purpose of minimisation of losses of a hydraulic liquid uncover tank GTTS, enclose under it a polyethylene film and densely screw on a place.
2. Carefully wipe the valve-regulator subject to removal and surface ГТЦ round it.
3. Give накидную штуцерную a nut, disconnect a brake tube, then turn out the valve-regulator from the main cylinder. Remove and will throw out an old sealing washer э at assemblage it is subject to replacement without fail. At once закупорьте the open ends of a tube and the union for the purpose of minimisation of losses of a hydraulic liquid and in order to avoid hit in dirt system. Traces of the spilt liquid at once смойте plentiful quantity of cold water.


Sensitive to degree of loading of the car the valve-regulator

 PERFORMANCE ORDER

1. Prop up wedges forward wheels, then поддомкратьте a back of the car and establish it on props.

2. Mark position of a head of a bolt of a spring of the valve in relation to the lever. Give a nut and remove a bolt of fastening of a spring to the valve. Remove washers.

3. Carefully wipe unions of brake lines and surfaces surrounding them, substitute under штуцерные connections drain capacity. In order to avoid mess, mark the valve and the tubes brought to it.
4. Give накидные штуцерные nuts and disconnect brake tubes from the valve. At once закупорьте the open ends of tubes and an aperture in the valve for the purpose of minimisation of losses of a hydraulic liquid and in order to avoid hit in dirt system. Traces of the spilt liquid at once смойте plentiful quantity of cold water.
5. Turn out fixing screws and remove assemblage of the valve from a basic arm.

INSTALLATION

Pressure sensitive to change valves-regulators

 PERFORMANCE ORDER

1. Clean a carving штуцерного connections on ГТЦ and the valve. Replace sealing washers. Screw the valve on the union and strongly tighten it.
2. Connect to the valve a brake tube, strongly having tightened накидную штуцерную a nut.
3. Clean a polyethylene film from under a cover of tank GTTS and completely pump over brake system (the Section Prorolling of hydraulic system see).


Sensitive to degree of loading of the car the valve-regulator

 PERFORMANCE ORDER

1. Get valve assemblage on the regular place and strongly fix its screws.
2. Connect brake lines to the unions on the valve (be verified with the marks put in the course of dismantle) and strongly tighten накидные nuts.
3. Establish a bolt клапанной springs, having tracked correctness of placing of washers. Screw a nut. Achieve combination put at removal of a bolt of labels and tighten a nut with demanded effort.
4. Clean a polyethylene film from under a cover of tank GTTS and completely pump over brake system (the Section Prorolling of hydraulic system see). Composers of the present Management recommend to drive away the car on a car repair shop for check of serviceability of functioning of the valve-regulator.
