Alfacapone sent me this guide and so far so good.
remove lower trim panel under steering wheel in drivers footwell, (2 plastic nuts)
- loosen the mounting bolts for the master cylinder - to allow the push rod to be manipulated
- with a large flat bladed srewdriver gently prise off the circular bush holding the pushrod onto the pedal
- clean off the old "silicon" (I think) grease, mine was bone dry
- put real olde english general purpose grease on the pivot
- put all back, tighten up fixing bolts, replace trim
Not issues for last 8 months job done!!
Hope it helps.
