A bit worrying
« on: June 25, 2015, 03:58:10 pm »
This morning on my way to work, I came up to a red traffic light, at which I had to brake a little more than usual.

However when I did, the bloody bike almost jumped!  Like the brakes were seized at the front, it momentarily let go, jolting me and then braked normally.

After that I tested the brakes a few times and they seemed okay.

This is quite concerning as I wouldnt want this sort of lock up to occur at speed.

Any thoughts - anyone?

thanks

Felt like the ABS to me.  Think I will have to take it in and get it checked out

I believe ABS should not kick in below a certain speed perhaps it got confused???  Or it thought you might go for it and jump the lights   :005: the electronics is getting ahead of itself.

No offense but given that you can't duplicate the problem is there a possibility of excessive human input due to inattentiveness in the first instance but which is no longer there now that you are paying attention?

Might also be worth going back and checking that part of the road for spilt OIL,
or loose gravel, or a metal drain cover ( or similar ), or a patch of white paint,
all of which could cause a momentary locking up of the wheel as it passed over it,
and might not have anything at all to do with the ABS  :169:

Was the road clean? What I am thinking is if  the ABS was activated and released the brake and you then felt a jolt when the brake was re-engaged when both wheels equaled their speeds.

BTW, if the front wheel stopped, such as a front wheel skid, you would have gone down. Perhaps the ABS saved you.
