Toyota RAV4>> Brake system>> Check and replacement of the vacuum amplifier of brakes>> Check
The vacuum amplifier of brakes increases the effort attached to a pedal of a brake, facilitating thereby driving. The principle of operation of the vacuum amplifier of brakes is based on depression use in an inlet collector. At an exit of the vacuum amplifier out of operation operability of brake system is not broken, but for pressing of a pedal of a brake it is necessary to make the bigger effort is considerable.
Press a brake pedal several times at the idle engine to create in cavities of the vacuum amplifier the identical pressure close to the atmospheric. At the same time on the effort enclosed to a pedal, define, whether there is no jamming of the case of the valve. Stop a brake pedal in the middle of its course and get the engine. At the serviceable vacuum amplifier the brake pedal after start-up of the engine should leave down. If the pedal does not leave, check fastening of a tip of a vacuum hose, connection of a flange of a tip in the amplifier, a hose and union condition.
Wait two minutes and switch off the engine. Press a brake pedal. With each next pressing the pedal should become is firmer, and the course of a pedal to decrease.
