What is the reason for the Carter 336 excavator rotary brake not working?

There may be several reasons why the CAT 336 excavator can not rotate the brake:

1.There is air in the brake fluid pipe: brake fluid is the medium of the brake system transmission, if there is air in the pipe, the brake fluid under high pressure is not enough power, although there is still a certain amount of braking force, but significantly weakened. At this time should be timely to the maintenance shop for brake system exhaust processing.

2. Brake fluid has not been replaced for a long time: brake fluid has strong hydrophilicity and easily absorbs moisture in the air. If it is not replaced in time, it will contain too many impurities and water, which will affect the transmission of braking power.

3. Oil leaks or soft brakes: Generally speaking, oil leaks from the brake master cylinder or brake pipe will cause the brakes to become soft. If the brake material is too soft, the high temperature stability will be poor, which will also lead to soft brakes.
