Dealer fuck up? Motorcycle abs freakout/fade

That cap is just there to keep crap out of the bleed screw. And if they did bleed it at all, it isn't uncommon for there to be a drop of fluid come out of the bleed screw after they tighten it down.

Doesn't seem to be related, especially in light of your other replies below.

Without looking at it, it's impossible to assess the bolt and/or other hardware that secure the sensor. Ordinarily, one does not have to open the bleed screw when replacing pads unless someone added a bunch when the pads were worn, but if they did, it may need to be bled. I agree with Kazoo, your first call is to the dealer that installed the tires, to allow them to make it right. I'm not certain why they would even need to remove the sensor to install tires, but clearly they did.

Got to looking after dinner. Found the front abs sensor bolt hanging by a thread and the sensor out an inch or so. So there's that culprit and me still wondering if I've got air in the system from a faulty bleeding since I've got that liquid and cap off.


Should there be any kind of thread locker on that bolt? When I tightened with an allen key I was suprised how few turns into the tight position and not much of a usual cinching it down sensation, just hit the wall and stops.

Based on the microfiche, there isn't any washer there, the sensor probably has a brass or steel insert which acts as a positive bolt stop. I would probably use a drop of blue (medium strength) loctite on the threads, and it will tighten to 12-14 ft-lb (or kind of snug when holding the ratchet by the head)for 8 mm threads. If you're using an allen wrench, just snug works. They show the bolt size as 8x16 mm, so not a lot of thread engagement there.

Can you pull the ABS fuse and just ride without ABS? I've heard of people doing that on cars.

Not a permanent solution obviously but if it happens on the road again that might at least get you home.
