- metal pipelines must not have nicks, scratches, abrasions, active corrosion centers and must not be located near sharp edges that can damage them;
- brake hoses should not have visible cracks on the outer casing and traces of abrasion; they should not be exposed to mineral oils and lubricants that dissolve rubber; press the brake pedal hard to check whether the hoses have any bulges, indicating that they are not suitable;
- all pipeline fastening brackets must be intact and well tightened; loosening of fastenings or destruction of brackets leads to vibration of pipelines, which can cause their breakage;
- no leakage of fluid from the connections of the master cylinder with the tank and from the nipple is allowed; if necessary, replace the tank bushings and tighten the nuts without twisting the pipes. Eliminate any detected faults by replacing damaged parts with new ones. Replace flexible hoses, regardless of their condition, with new ones after 125,000 km or after five years of vehicle operation to prevent sudden hose ruptures due to their aging.
The brake fluid level in the reservoir is checked visually using the marks on the reservoir body. With the cover removed and new brake pad linings, the fluid level should be at the "Max" mark. If the brake hydraulic drive is in good working order, a decrease in the fluid level in the reservoir is due to wear of the brake pad linings. A decrease in the fluid level to the "Min" mark indirectly indicates their extreme wear. In this case, it is necessary to directly monitor the condition of the pads, and do not add fluid to the reservoir, since when new pads are installed, the fluid level in the reservoir will rise to normal.
