rear ABS problem

[juniorfjr]

Last fall had to replace back tire. I removed the tire and wheel, following the instructions on fjr tech. Pretty straight forward job, dealer mounted new strada I had purchased. I reinstalled everything without problem, making sure the marks line up on the abs sensor. Now when I dynamite the rear brake the ABS works very rough and pulses long and hard, I can feel it in the brake pedal. thunk, thunk, thunk. Service guy at dealer just looked at me like a deer in headlights. Anyone experience this, or have any ideas on what to tell the guy to look for.

thanks, Fred

Just a comment and a guess...

Maybe you should use the front brake more and stop 'dynamiting' the rear brake?

Maybe your new (and probably unscrubbed) tires offer less traction than your old ones and the ABS is just working more to make up for that?

Also, maybe your just getting out from winter storage and the roads are still grimy with salt and sand?

I read somewhere (OEM service manual?) that Yamaha intentionally makes the pedal/lever pulse noticeably so the rider knows when it's working that traction is reduced. Makes sense to me that the more it does it's thing that it would also be more noticeable.

I can feel it in the brake pedal. thunk, thunk, thunk.

That's how mine feels when the ABS kicks in. I think it's normal.

+1 on the normal, that's how it's supposed to feel. You may have accidently fixed it

I commonly get the ABS to kick in when I combine hard deceleration, braking, and downshifting. Weight transfer will do this. But what I'm reading in his post is a change in the ABS application and feel, not that it's coming on. He's not responding. I love when folks do a post and bail while the rest of us play charades with what we think they might have been trying to say............. :blink: Does it feel larger than a breadbox?

That sounds like the way mine has worked from day one.

sorry about the delay getting back. The ony reason I brought it up is I don't remember it so much last year, before the tire change. I rarely use the back brake, but wanted to know it was there just in case. Sounds like its normal.
