As one of the guys having the same issue , I still have the problem. I had changed the fluids + done the caliper cleaning but it still is the same as you all can imagine. Shortly I am trying to leave with it and getting really used to and braking the rear as gently as possible inorder to not to lock it.

UPDATE:

So, the Dealer confirmed what we pretty much knew, that the hydraulic unit is bad. The service advisor at Riva Motorsports (Miami, FL) called Yamaha at my request to ask if they would help with the replacement (parts $1306.99, labor $200). Yamaha declined.

Today, I called the customer relations department and spoke with the purported FJR product specialist. After he spoke with his hierarchy, the decision was still to decline to help. They said the hydraulic unit is subject to wear and with 25K miles and six years, blah blah blah.

I restated that there are a bunch of 1st gen bikes that have reported this problem on the internet, he asked me to send the links, which I did this afternoon.

I can't afford $1500 right now. Have not been able to find a salvage hydraulic unit. Will ride without ABS for now. Will update if any further developments.

David,

Check THIS out. $149. Could be your salvation!?

Just found ANOTHER for only $39!

I'm assuming you didn't search eBay?????

Gen 1 is different part, these won't work.

And......HERE'S one for a Gen I.

Thanks Howie, great find. I bought it. Seller has excellent rating and claims to accept returns if not functional, so I'll take a chance.

Brilliant news :clapping: now all we need is a volunteer to carry out an autopsy on the 'failed' unit

Don

There are several of us that have volunteered to autopsy the metering block. Perhaps David could auction off the privilege to recoup his costs for the replacement metering block

Let the bidding begin...

Actually, I think I'll keep it for a while until I'm sure the used replacement works. At least the front circuit seemed to be working on the bad one.

Good find!

Ya know, I had said that on my FJR with the ABS not working that it was both front and back. Well..... it's actually only the rear that is not working, just like yours. Front works just fine. Still haven't had time to diagnose, but I am assuming a bad metering block.

So keep looking RH!

I wonder if it is the case that the rear circuit seems to fail most often. Granted, a limited number of cases that I know about, but I can't recall reading about a front-only failure. If this is true, what would account for that?

I am somewhat annoyed that Yamaha (well, at least the product specialist I spoke with) considers this very expensive part essentially a "wear item" and says they expect such items to wear out on a bike with 25K miles over 6 years.

I hope everybody who has had the problem has reported it to NHTSA....https://www-odi.nhtsa.dot.gov/VehicleComplaint/index.xhtml

It is even more curious because the rear ABS is more likely to get actuated than the front which should transfer fresh brake fluid into the metering block and keep the spools working.

I had the same thought.

My guess would be that people that have the front circuit fail just never notice it. The back wheel locks up (inadvertently) all the time. Not so with the front wheel. You have to actually try to make it happen.

UPDATE:

SUCCESS!!

The salvage hydraulic unit assembly I bought on EBay from Imperial Sportbikes (thanks to RadioHowie for the heads up!) for $269 seems to work as it should. Based on hydraulic unit test #2 (brake pedal now returns force) and a successful test ride activating front and rear ABS, I am a happy camper. In all, including the unnecessary extra failsafe relay and the extra salvage ABS ECU, etc., this saved me about $1100 compared to the cost of buying a new one and having the dealer install it. Yamaha corporate wouldn't help out with the cost in any way.

The installation was mostly a piece of cake. Unfasten two nuts that hold the complete assembly in place and disconnect the electrical and hydraulic connections, pull it out without drama, pop in the replacement assembly, reconnect everything, bleed the system, do the hydraulic unit test, bleed once again, do a test ride, done. Snafus included 1) having a devil of a time re-fitting the plastic tray that lies under the seat and holds the engine ECU and rests above the ABS ECU...I have no idea how the electrical connectors were supposed to go in and be out of the way far enough to get the tray back in place. It's still a little canted at the rear, but to hell with it, 2) breaking a few of the plastic rivet thingies, and 3) ending up with a few allen head screws that I haven't been able to find the holes in the plastics for.

I had a couple of 8mm SpeedBleeders left from a previous bike that I sold before installing them, they fit the FJR so I installed one in the front left caliper and the other in the clutch. I had to order the LL model for the right front caliper and a different model for the rear caliper, but I'm now a believer. Anybody want to buy a used MiteyVac?

Thanks to everyone on the Forum who gave me guidance and encouragement. I hope my saga is finished now, knock on wood. If anybody wants a talk-through if they do it themselves, just PM me and we can get together online or on the phone.

I, for one, am very glad to hear this. It gives some hope and good direction to the other folks that have a similar situations pending. It's just a matter of finding a source of good salvage ABS hydraulic blocks, and they can also be back in business.

Big thanks to David for keeping us all posted on his journey through this infrequently visited repair area. Nice work. :thumbsup:

 

[ionbeam]

Whew! Glad it has a happy outcome :yahoo: You did a great job of troubleshooting. This thread should be a helpful guide for any else that is having brake system symptoms like yours. It's great that you found a good used hydraulic block.

 

[RadioHowie]

All I can say is............HALLE-FRICKIN'-LUJAH!!

Might I suggest boxing that old pump up and sending it to Ionbeam for a post-mortem? He's the resident "Fart Smeller" and his expertise could save generations of FJR Peeps future head pains.

Congrats on the fix! :yahoo: :clapping: :yahoo:
