SEQUENCE OF WORK
1. To determine leaks in the hydraulic drive of the brake system, it is necessary to ensure that the vehicle is parked on a dry floor or platform.
2. Check up branch pipes and connections of hoses and pipelines, brake supports and protective casings with the wheel brake cylinders of back wheels located behind them. Pay attention to dark and wet spots.
3. Check hydraulic brake hoses. Brake hoses must not be wet, bulging, frayed. Otherwise, replace them.
4. Clean with detergent (diluted in cold water) hydraulic hoses and pipelines. The brake pipes are coated with plastic to protect against corrosion. If this layer is damaged, corrosion can begin. Therefore, never clean the pipelines with a screwdriver, sandpaper or wire brush, use only a cleaning agent. If the protective layer is damaged, it is necessary to apply a thin layer of anti-corrosion primer. Pinched or corroded lines must be replaced immediately.
5. Check up, whether there are protective caps of unions of prorolling on all brake calipers.
6. Check brake fluid pressure regularly in spring and autumn. With all your strength, press the brake pedal and do not release it for 1 minute, while it should not go down further. If this happens, then the sealing rings in the brake master cylinder are damaged. Due to leaky O-rings, the brake fluid level in the reservoir does not drop, and the pressurized fluid flows past the piston in the master cylinder to the side where there is no pressure. Leaks in brake caliper pistons can be identified by dark spots around the O-rings. If you doubt the tightness of the brake system and cannot independently determine the location of the damage, contact a service station.
