The condition of the hydraulic drive is checked visually. Leakage of brake fluid is not allowed.
Metal pipelines should not have dents, cracks, they should be securely fastened away from sharp edges that could damage them. All brackets fixing the pipelines must be securely fastened, because. vibration can cause pipe breakage.
All fittings must be securely tightened - leakage of brake fluid through them is not allowed.
Brake hoses must not have cracks in the outer sheath and must not come into contact with liquids that dissolve rubber. The condition of the hoses is best checked with an assistant who must press the brake pedal hard and hold it during the inspection. Blisters on hoses are not allowed. Regardless of the external condition, the hoses must be replaced after 100 thousand kilometers or five years of vehicle operation.
Brake fluid is usually replaced after five years of operation, as it is highly hygroscopic (easily absorbs moisture from the air). But, based on practical experience, we recommend replacing the fluid after two years. Water in the brake fluid increases the likelihood «souring» working cylinders from corrosion and lowers its boiling point.
