- metal pipelines should not have dents, cracks and should be located away from sharp edges that could damage them;
- brake hoses must not have through cracks on the outer casing and must not come into contact with mineral oils and lubricants that dissolve rubber; press the brake pedal hard to check if there are any bulges on the hoses, indicating a malfunction;
- all brake lines must be properly secured; loosening of the fastening leads to vibration, which causes breakage;
- liquid leakage through pipeline connections is not allowed; if necessary, tighten the fittings until they stop without deforming the pipes.
Replace parts with new ones if there is the slightest doubt about their suitability.
Flexible hoses, regardless of their condition, should be replaced with new ones after 100,000 km or after 5 years of vehicle operation to prevent sudden ruptures due to aging.
After five years of operation, it is recommended to replace the brake fluid with new one.
