If you are still using a four piston caliper then the original master cylinder should be ok, you will of course benefit by fitting a later more up to date master cylinder. The only time you really have to change the master cylinder is when you change from a two piston caliper to a four piston type, then you need the extra capacity/ratio of a master cylinder suited to a four piston caliper. As a point of interest, I chnaged the original 2 piston calipers on my Jota to four piston Brembo`s and fitter AP Lockheed ajustable ratio master cylinders which I can only praise in terms of performance and quality of construction. |
