2013 Defender 110 - Brake issue

pressed the brake peddle, got the bobbling effect as if ABS was activated, but I was going very slowly. It then worked as per normal again (firm feel and not depressing to bottom) before doing something similar with an accompanying scrape noise. I will take her to my trusted garage on Monday, just wondered what people thought?

Have you looked to see if you have any pad left on the brakes, or if there is any fluid in the res ??
