hi there mate there is no manual adjustment. the problem with the maxus is the flex in the pedal box if you stick your head down by the pedal look up and press down you'll see wot i mean. The fix was a brace modifcation by ldv themselfs but as they are no longer its not avalible. but its really easy to make your own. you need a length of reasonable strength flat plate. bend it one end to fit on bottom bolt of master cylinder and other to fit bottom left bolt of the pedal box this takes out your movement therefore giving you a better pedal. hope you get on ok
