Radial clutch cylinder sizing

follwing other post, which bore woudl be best on a 996? I have a 19x20 (I think!) brake to fit, would 16x18 be right for the clutch?

what difference does the bore make?

the brake and clutch sizes are differant, thats not unusual.

diffreant sizes give diffeant level of feel / pull rate, for example on the brake you can overdoit and remove the feel from the brake, clutch is similar scenario but less crucial.

so which would you go for mate - 16x18 a good compromise on the clutch?

The early OEM clutch pump master cylinder has a 13mm bore. 13x20 (measured.) The master cylinder got a smaller piston for 2001 (the ones with the silver levers.) This is good for about a 10% reduction in pull force.

When using the larger bore 16x18 (the smallest one Brembo makes) you'll find that it makes the lever harder to pull than the stock master. This should be used with an oversized slave cylinder for a reasonable pull. If you have a 2001 or later updated slave cylinder you'll be OK.

so, in laymans terms.....what it an oversized slave cylinder? is that the plastic thing which holds the fluid?
maybe a good reason to chnage to an anodised one.....

The clutch slave cylinder is the one by your left boot when you're on the bike. Where the front sprocket cover is.
