Juddering brakes..but only in wet...

OK, anyone any ideas on this?

rakes have started doing a rather odd juddering under firm braking, but
*only* in the wet. In the dry, I can do very firm braking, up to nearly
an emergency stop, and nary a judder to be felt.

But in the wet, as bike comes to a halt, juddering is felt. Only time I
have ever felt anything similar was when the head bearings were shagged,
but they were replaced about 1000 miles ago, and are properly torqued up.

Lines are a relatively recent braided SS replacement set, and as said,
stop bike admirably in the dry.. Disks are not warped at all.

Disks are EBC Prolites, and pads are HH..
Bike is Fazer 100.

Any ideas Oh FOAK?... Im confused..

 

Try OE pads.

 

Sucking his keyboard for inspiration, Spike typed:

If all is well in the dry, then it's something to do with the pad/disc
interface getting wet. There's nothing else that could be affected by water
AFAICS. Are the pads contaminated at all?

 

Probably the ABS cutting in. Good, innit?

 

The water has caused the engine to shrink. Dry it out and all will be
well.

I was trying to think of an appropriate remark...well done
