General description
Note. Some 2.0L 16-valve Coupe models are equipped with rear disc brakes. At the time of writing this Guide, there were no published data on these nodes.
The brake hydraulic system is equipped with an amplifier and is divided into two circuits. Each of the circuits controls one of the front and diagonally opposite rear brake assemblies. The circuits are connected to a common master cylinder. Under normal circumstances, both circuits work in unison. However, in case of failure of one of the circuits, braking will be carried out by the second circuit, on two wheels.
All models - equipped with disc front and rear drum brakes (except 2.0l Coupé models with 16 valves). The front ones are equipped with sliding type calipers, driven by a single piston cylinder. In this case, equal pressure is applied to each of the pads. The rear drum brakes have driving and driven shoes, which are actuated by a working cylinder with paired pistons. A self-adjusting adjuster built into the brake assembly automatically compensates for increased clearance due to pad wear
A load-sensing pressure control valve is mounted in the hydraulic line of each rear brake mechanism. The valve is connected to the rear axle and adjusts the pressure in the system according to the axle load, which helps prevent the rear wheels from locking up during emergency braking.
The hand brake provides the use of rear brake mechanisms through an independent mechanical drive.
Note. When performing maintenance on any part of the system, work carefully and methodically and be meticulously clean. Replace Component (along with its pair installed on the opposite side of the car), if there is any doubt about its condition. Use only genuine Renault parts or at least good quality parts. Take heed of the Asbestos Dust and Brake Fluid Hazard Warnings in this Chapter.
