The general description

Some 2.0 l of model of the Compartment with 16 valves are equipped by back disk brakes. By the time of a writing of the given Management any data concerning these knots in the press was absent.

The brake hydrosystem is equipped by the amplifier and divided into two contours. Each of contours operates one of lobbies and диагонально opposite back in brake knots. Contours are connected to the general main cylinder. Under usual circumstances both contours work in a unison. However in default one of contours braking will be carried out at the expense of the second contour, on two wheels.
All models - are equipped by disk forward and back drum-type brakes (except 2.0 l of models of the Compartment with 16 valves). Lobbies are supplied by the supports of sliding type put in action by the cylinder with the unary piston. Thus equal pressure is applied on each of колодок. Back drum-type brake mechanisms have conducting and conducted Pads which are put in action by the working cylinder with pair pistons. The self-adjusted regulator built in brake knot automatically compensates the increase in a backlash caused by deterioration колодок
In a hydrowire of each back brake mechanism the valve sensitive to loading to pressure adjustment is built in. The valve is connected with a back axis and corrects pressure in system according to loading on an axis that helps to prevent blocking of back wheels during emergency braking.
The manual brake provides application of back brake mechanisms by means of an independent mechanical drive.

At carrying out of servicing of any part of system work accurately and methodically and carefully observe cleanliness. Replace a component (together with its pair established on an opposite side of the car) if there are any doubts concerning its condition. Use only firm spare parts Renault or, at least, high quality details. Take into consideration Preventions concerning danger of an asbestine dust and the brake liquid, resulted in this Chapter.
