series 3 - conversion from drum to disc brakes

my right hip is starting to complain because of the pressure required to stop my series 3. I am wondering if changing my front drum brakes for a 90's disc brakes would help my right hip? is this achievable?
any words of wisdom out there????????

ok to start, a series 3 is not a 90 or ninety, they came later.
i might be out of date but last i heard (long time ago) you needed to replace the axles to get disc brakes.
i would also say, if you have a functioning servo with well maintained/serviced brakes, the effort shouldnt be excessive.
i dont know how it would affect your insurance, worth checking before you start anything

thanks for that useful comment.I am aware of the different models as i have owned them over many many years of being a landy lover.
