5 Before getting into the actual brake bleeding process, it is always a good idea to give the braking system a complete inspection. Any leaks or hardware out of adjustment can cause a soft pedal; tricking you into thinking you have air in your system. Brake hoses and banjo fittings (on late-model brakes) use copper sealing washers on the bolt or hose end. Be sure a sealing washer is in place and the line is secure. We recommend replacing these washers any time the connection is opened.
