Repair and car operation

Check, removal and installation of the valve of adjustment of pressure in back brake mechanisms

SERVICEABILITY CHECK

1. In a hydrowire of each back brake врезан the valve of adjustment of pressure sensitive to loading. The valve is attached to the bottom of the car and connected to a back axis. The valve defines loading received by a back axis on its displacement and prevents blocking of back brakes at sharp braking. 2. To check up serviceability of the valve, the special equipment, therefore this work is required should be charged HUNDRED Renault. Valve repair is impossible, and if it is faulty, should be replaced. On the models equipped ABS before to turn on connecting муфты brake tubes disconnect a cable of weight from the battery and do not connect it, yet will not pump over system. If not to make it, air can get to the hydraulic block which it is very difficult (in certain cases it is impossible) to pump over.

REMOVAL

1. Minimise liquid loss, having enclosed under a cover of the tank of the main cylinder a polyethylene piece. 2. Block forward wheels, then поддомкратьте a back part of the car and establish it on axial props. 3. Rub off area round connecting муфт brake tubes on the valve and enclose under муфты rags to catch a liquid which will be let out. Not to mix valve ports at installation, mark them concerning tubes. 4. Loosen the connecting nuts also separate brake tubes from the valve. Закупорьте the ends of tubes and a valve aperture to minimise loss of a brake liquid and to prevent penetration of a dirt into system. Смойте the spilt liquid cold water. 5a. Turn away fastening bolts. 5b. Then disconnect draught of the valve and remove assemblage from under the car (address to illustrations). Do not weaken a bolt of a clip of draught is will lead to change of length of draught, and at installation valve adjustment is required.

INSTALLATION

1. Deduce valve assemblage into position and tighten fastening bolts. 2. Establish brake tubes in муфты on the valve and tighten connecting nuts the effort resulted in Specifications. 3. Attach draught of the valve скобами and lower the car on the earth. 4. If new assemblage of the valve is established, pay attention that it is supplied special распорной by a lining intended for adjustment of length of draught. Achieve a rated load on a back axis (the car leans against wheels, the fuel tank is filled and on a driver's place the person), ослабьте a bolt of a clip of draught sits and allow to a valve spring to establish length of draught. Reliably tighten a bolt of a clip and remove from draught распорную a lining. 5. Remove polyethylene from under a cover of the tank of the main cylinder and pump over all brake system as it is described in Section Prorolling of hydrosystem of brakes.
