Hi, I've just bought a 2014 Crossrunner with 6k miles. On my first ride out (400miles) my bike's front brakes, on two occassions, locked up from pulling away at traffic lights. A light press of the front brake level and release and away it goes again.
It is currently in the service shop who have stripped and cleaned the brakes and are finding that not all the time but sometimes the pistons are not returning and are hard to return if forced. They are about to check the lines for any kinks but have mentioned that it could be a delay valve or the ABS pump. These items are not cheap and it seems like I have to buy the items for them to be fitted one by one until culprit found.
Has anyone had this experience and know what may be the cause?
