If the wheel brake cylinders or brake calipers start to inflate automatically, it is often because the brake hose is blocked. The brake fluid will be pumped to the brake cylinder or caliper, but it will not be able to flow back.
Whatever the reason for replacing your brake hoses, always replace them left and right. If you do not, there is a good chance that there will be a difference in braking pressure, the vehicle will pull to the left or right when braking.
Make sure that the brake hose is installed without rotation, a bent brake hose can be identified by the curved lines pressed into the outer shell of the brake hose. A bent brake hose will be rejected during the periodical technical control.
