Brakes

General description

For the vehicles equipped with additional system "air bag" (a safety airbag):

  • Service of components of an airbag of safety ("air bag") and near them or works with electroconducting should be carried out only by the authorized dealer of SUZUKI. Non-compliance with security measures can lead to inadvertent operation of system or put system out of action. Any of these two conditions can lead to a serious trauma.
  • Works on maintenance should be begun not earlier than in 90 seconds after the ignition switch is transferred to the situation "LOCK/LOCK" and a negative cable disconnected from the battery. Otherwise the system can be activated by reserve energy of the module of sensors and diagnostics.

  • At survey and service of the vehicle equipped with ABS, surely at first address to Head Anti-blocking brake system (ABS).
  • All fastenings of brakes are important elements of fastening and can affect work of the vital details and systems, and/or considerably to affect repair cost. It is necessary to replace them with details having the same number or equivalent if such replacement is necessary. Do not use for replacement of a detail of the worst quality or substitutes. It is necessary to observe the specified values of a torque of an inhaling at assembly to provide long service life of all details. It is not necessary to use welding as it can lead to extensive damages and weakening of metal.

When it is pressed foot brake, in the main cylinder the hydraulic pressure putting in action pistons (two in front and four behind) is created.

The main cylinder – double-circuit. Brake highways are connected to the main cylinder and form two independent contours. One of them connects forward brakes (right and left), and another – back brakes (right and left).

For vehicles without ABS between the main cylinder and a back brake the valve of restriction of brake effort is switched on in these contours in proportion to loading (LSPV).

In this brake system, for brakes of forward wheels the disk brake system, and for back brakes – system of drum-type type is used. (Conducting/supporting blocks).

System of the parking brake - mechanical. It puts brake effort only to back wheels by means of a cable and system of mechanical interrelations. The same brake shoes are used as for lay, and a foot brake.

Drawing shows a vehicle with the left wheel.
