StagNL Posted April 25, 2013 Share Posted April 25, 2013 I'm not planning to be near my [s]car[/s] collection of bits until wednesday/thursday next week. Maybe before then someone else will chirp in with the specs. But, and it is a big but, I might get the info this evening.Julian Quote Link to comment Share on other sites More sharing options...

mikew Posted May 4, 2013 Share Posted May 4, 2013 stagdad wrote:Mike did you have to move the clutch M/C over to fit the bmw servo in?Cheers SteveYes, this moves 30mm or so towards the centre of the car, on a bracket that you weld to the pedal holder. the pedal remains where it is, and uses an offset pin to connect with the master cylinderthe inner wing requires modification too ( large hammer required) to make a little space for the larger servo, and the servo mount holes need redrilling.It reduces pedal pressure enough for Anne to be comfy driving it. ALso replacement bmw master cylinders are £38 so when it needs attention its cheap Quote Link to comment Share on other sites More sharing options...
stagdad Posted May 5, 2013 Share Posted May 5, 2013 That brill Mike thanks,i already have the bmw servo and M/C sitting in my shed.I know of a few fitted to autos but you are the first i know off to fit it to a manual and was wondering if it was easily do-able,doesn't sound too bad.Cheers Steve Quote Link to comment Share on other sites More sharing options...
mikeyb Posted May 5, 2013 Share Posted May 5, 2013 so I'm guessing a new hole has to be made in the bulkhead for the clutch master too then? Quote Link to comment Share on other sites More sharing options...
