Sounds like you made a good choice !

If you like the bike I'd recommend getting another parts bike.  For 2000 bucks you might as well spend a little more and get another bike.

Bike is only worth around just shy of 3500 $$

My thoughts on this are that I've never seen an ABS pump fail in such a way that it only affects one circuit and not both.  That strikes me as odd.  I guess it may be possible, but odd.

The second thought is about the cost.  It's probably a Bosch pump, and therefore the cost is going to be the same as a BMW part, because it will be the same as a BMW part.  I would look around and see if any can be sourced from used part dealers.  Really, there should be no problem finding one (It's probably the same part number used in many, many bikes).

Third, replacing an ABS pump isn't brain surgery.  Any reasonably competent mechanic should be able to do it.  If you feel able to replace a brake component such as a caliper yourself, then it really won't be a whole lot more work.

Yeah that's a weird failure. I'm betting against it being a Bosch pump.  If it was then Module Masters would be able to get it going. Not so much a factor now that a second hand pump has been sourced.

Good luck with the repair.

So...my understanding (correct me if I'm wrong) is that the ABS hydraulic unit (also simply called the "ABS pump") is a part of the fluid circuit for the entire braking system. And if this pump has "seized up" (not exactly sure what that means—these are the shop's words), it's not simple to just restore normal braking function without ABS. Because (I think) the only way to do this is to rig the brake lines to bypass the ABS pump.

If this is correct, then this may be why the shop has been stalling. (I just assumed it was quick-n-easy to do.)

Regardless, I called them this morning and told them I found a second-hand ABS pump online and bought it, and asked if I brought it down there would they install it? They said sure, bring it down.

So that's the plan now. They're already into a $200-300 worth of work on the bike, so it's worth not having to take the time to do it myself to have them do it. (While they haven't been ultra-communicative and detailed in explanations, I've seen no evidence that their work is shoddy or unsafe.)

I should get the new-used pump tomorrow or Wednesday, so stay tuned!

You are correct.  To bypass the ABS pump would require new brake lines.

The shop says because the ABS pump seized up, the entire ABS system needs replacing—to the tune of $2,000+.  EEK!   They also said they could just remove the ABS system entirely for $400.

My question for you guys is, does this all sound plausible? Or does it sound like bullshit?


First, I am not an expert on ABS or motorcycle maintenance, BUT I call BS.  Largely because a lot of shops (sadly) try to exploit the "stupidity" of the average owner and ASSUME they don't know anything about fixing things.  I go to a mechanic because I don't have the right tools and/or time to do it myself.  It doesn't mean I don't know HOW to fix something myself.

Normally everything is a series of components.  The failure of one almost never affects the other parts (taking them down with it).  You should be able to replace the ABS pump, thoroughly flush out the brake lines, and everything SHOULD work properly.  The black fluid only shows contamination, not that the calipers are damaged.  Every ABS pump should operate like a standard master cylinder if the ABS functionality fails.  You'll get an ABS light or error code, but the brakes should work properly.

As far as rear not working but front working, any system where one master cylinder services all wheels likely baffles output so if one part fails, you don't lose everything...although it's odd that a rear wheel failure doesn't automatically shut off the whole system.  Every automobile is designed so that the front wheels and rear wheels are on separate circuits and the reservoir is baffled to separate fluid once it runs low.  This way, if you have a catastrophic failure on the front or rear brakes, you still keep the other two wheels for stopping.  Hence why you can't kill a person by just cutting ONE brake line.

You might try going to a forum that has "experts" on ABS systems (a mechanic or DIY site perhaps) and see if others have had to do a full system replacement or just fix the damaged part(s).

For what they are trying to pull, I'd sooner remove the ABS function for $400 than pay $2,000 for a needless batch of repairs.

And the bike is sitting at the shop and I don't have a trailer.


Buy a couple of ratchet tie-downs and a motorcycle ramp and ask someone with a pickup truck to help you get it home.  Cool

I was just in my local shop the other day and overheard a conversation with a guy agreeing to a $4400 quote for repairing his ABS...  I'm assuming its a newer BMW otherwise I'd put that money towards another bike.
