Among us, there must be an experienced brake problems when driving. For example, although the car brake grip (gripping tightly), but it often feels hard pedal when stepped on. Occasionally soft, but more often harder. Though the master brake has been replaced. Brake was new and still thick. But, it turns out this problem remains unresolved.
Is that because the brake booster? Indeed, the case surrounding the brakes will inevitably involve a component called the brake booster. Maybe also on the machine. Including the problem of the brake pedal hard. Among these components, most likely the brake pedal hard problems triggered by damage to the brake booster. Therefore, the brake booster is constructed to make the brake pedal lightly.
To detect whether or not defective brake booster, do the following steps. Turn the ignition to the OFF position (engine off). Roll (tap-off) brake pedal repeatedly to get the highest position of the brake pedal (foot still pressing the brake pedal). Turn on the machine. By the time the engine is on, the brake pedal will go down by itself (the position of the foot still pressing the brake pedal).
Then turn off the engine. At the time the engine dies, then the brake pedal must remain at the lowest position, and the pedal will go up if we do the reshuffle. When the test results did not correspond with the steps above, it is likely the source of the problem is the brake booster. Well, if proven that the brake booster problems, to overcome them should bring your car to the garage.
Because, to handle a minimum of brake booster must be replaced. In fact, it may also need to overhaul. For these two things, of course, should not be done alone. Then, what if the results of detection according to the steps above and showed no damage in the brake booster? Maybe the damage actually occurred in the installation of one way valve, or in vacuum.
