A brake hose may need replacing if you see cracks, bulges or swelling in the outer cover or fluid seepage at the hose or its fittings, or if the brake pedal feels soft or spongy. These symptoms can have other causes, so diagnose the brake system before replacing parts. The brake system must be bled after installation.
