Mentioned before elsewhere but MMC fitted their standard return spring to the clutch pedal on early 3.7 Roadsters at least until 2014, which includes all the Brookland models. I've sat in two of them and the pedal pressure is brutal although I guess owners who have known no different accept it.
The good news is that removing or just unhooking this external spring from the pedal leaves plenty of return action from the master cylinders own return spring. Indeed the clutch action still errs towards heavy. At some point after 2014 and certainly before 2018, the factory ceased including this spring although the handed brake pedal one remained.
