Just sharing my findings regards the front brake on my GTS300 ABS.
I was disappointed with the front brake on the my new 300 (2500 miles now), it felt almost wooden ! I tried roughing the pads up, cleaning the disc with brake cleaner, and bleeding it …. but it still wasn't as I thought it should be. It just had no bite, so I have fitted EBC sintered HH pads, this was an immediate improvement.
I also struggled to get the lever to "feel hard and not spongy" (probably a technical term for this !), I moaned to myself that when it was PDI'd at the dealers that the brakes weren't bled properly, but I couldn't get them any better even after a couple of tries, and I got no air out of the system ! So as a last resort I tried an old trick I have used on my sports bikes before, pulled both brake levers on as hard as I could and put a cable tie round them to hold the brakes hard on over night ……. bingo, next morning levers feel great Much more bite in the brakes now.
I am back in love with the GTS again !
