The brake liquid used in hydraulic system of brakes is poisonous, therefore at its hit on skin it is necessary to wash out immediately this place a plentiful quantity of water. If liquid got to eyes or in an organism, it is necessary to address immediately to the doctor. Some liquids have property easily to ignite and can light up even from contact to hot knots of the car. Besides, the liquid used in hydraulic system of brakes, dissolves paint and plastic therefore at liquid hit on a paint and varnish covering of the car wash out it a plentiful quantity of water. Also this liquid is hygroscopic, i.e. absorbs moisture from air and therefore the liquid, being stored in open ware, it is not recommended to use a long time.
Removal of a dustproof cap of the union of pumping of a back support of a disk brake on models with ventilated disks
Pumping of hydraulic system of brakes is necessary for removal of air which considerably reduces efficiency of braking. Air can get to hydraulic system owing to system depressurization at repair, replacement of separate knots or brake liquid. To availability of air in a drive points the increased course of a pedal of a brake and its softness. Before removal of air check tightness of all knots of a drive of brakes and their connections.
Never use brake liquid repeatedly.
At performance of operation of pumping of brake system let's to level of brake liquid fall below the tank middle.
If brake liquid left system because of leak in system, find the reason and eliminate leak before further actions.
If the hydraulic system was separated partially, and the corresponding precautions were accepted to prevent further loss of liquid, it is possible to pump over only a part of system.
Pumping can be carried out with the assistant or it is independent, a set of pumping of brake system. Always act according to the instruction. It is recommended to use a set everywhere, where probably as it very much simplifies pumping procedure. If the set for pumping is not present, it is necessary to be reserved by pure capacity and a transparent plastic tube of the corresponding length which should put on densely on the pumping union. Thus the help of other person is required.
Sequence of pumping
If only the partial rassoyedineniye of hydraulic brake system was made and the corresponding precautions were observed, it is enough to pump over only this part of system. If pumping of all hydraulic system of brakes is made, pumping of each contour begin with a forward wheel on models without anti-blocking system. On models with anti-blocking system first of all pump over a forward contour.
Pumping – the main method (two persons)
Pumping – set use with the unidirectional valve
The set consists of a tube with the unidirectional valve established on it which excludes possibility of return to brake system of remote brake liquid with air vials. On some sets the transparent container in which air vials in brake liquid are well looked through is established.
Pumping – use of a set of pumping under pressure
