Bypass GS unit and return to regular brakes........

[Dr. Curve]

I am hoping some brother out there has done a bypass job on a GS ABS unit. We have a bike here that has a ABS that has gone out. Rather that spend the money to find a new or used one..............why not leave the unit in place, and simply join income lines to the outgoing ones and by pass the actually unit. If you have done this job and have any hints of short cuts, please drop a note so I can see if it is something we should try here. It looks easy enough.......but we all know how misleading this can be. Thoughts........?

Sounds like an ABSectomy. There are several threads in the archive on that. IIRC

I highly recommend removing the pump & extra steel lines associated with the abs. It both eliminates a fair amount of weight & plumbing straight from master to brake calipers improves braking feel & control greatly. You don't mention what year the gs is but earlier ones without abs2 or iabs are far easier to remove.

ModuleMaster is another alternative. He rebuilds them better than original for a reasonable fee and you get to keep all the instrument lights etc working. Not too much more money than buying new SS lines.

Remove the pump if you decide to do away with your ABS. It must weigh five pounds and the space you free up makes a perfect location for wiring accessory mounting. I made an aluminum plate and attached it to the pump mounts to neatly anchor my wiring additions. I cut way the entire connector and tapped into the switched, heavy guage hot wire too.

[sgoodwin]

5 pounds? I weighed the pump & metal lines & it was around 15 pounds that I removed. But Curve never did respond as to what year GS he has as with the older ones you can remove the pump, ecu & metal lines unlike abs2 0r iabs which unfortunately require the ecu to be retained though it doesn't weigh much more than a pound or so.

[kroberts]

It was just a guess really. It is quite a dense little package.

Thanks so much guys, and I really appreciate the help. The GS in question is a 2006 and other than the ABS issues, it has no other problems. With cost being so high, the owner, and I, feel the thing to do is just by-pass the unit, removing it if necessary, and re-connecting the lines to each other in a regular fashion. If you can point me to other post that have talked about how to do this in detail, like making a line and its shape, or connect splicing using a disc brake line, which is my idea, or any innovative suggestions at all, this project can get going as to the parts needed. I also did not know of the module Master option..........have other gone that route in order to keep the electrics all happy? TIA for this help.

[Dr. Curve]

ModuleMaster is for 2007 units forward only. We are out there. More......

[Dr. Curve]

Any information on a this ABS bypass for a 2006 GS unit. Any help or tips will be used. Looking for a used unit as well but with no luck. Boneyards has none as of my last check out....... Other sources?

[sgoodwin]

Can't say I know sh it about an '06 GS but assume it is like the later 1100S units & you'll have to retain the ecu to keep your speedo & taillights working & avoid any codes. Just remove the pump & all the associated lines & call speigler & let them know what you're doing & need direct from master to caliper lines front & rear. I know on mine it was fun untangling the steel lines through the frame & wiring. Best of luck, you'll be amazed at how much better the brakes feel after taking the mush out.

[Dr. Curve]

Thanks Goodwin and I will do just that, by calling Speigler and let them send the one for a stock non-ABS bike, or whatever connectors they come up with. Sure wish we could just get this unit rebuilt but no such luck. Thanks all........and even more tips will be appreciated.

Here's a video on removing the iABS that shows how to hook up the brake lines to bypass the ABS unit. There's additional information on removing the ABS unit but DO NOT FOLLOW THIS PROCEDURE! If you remove the unit, follow the procedure where you retain the ABS electrical unit.

Thank you Tic, and more on this later, after the owner decides their money pool, and how much to alot. TIA

Hi Dr. Curve :

You might find this site in Germany of interest.
Seems like they now have their prices , and delivery schedules up since the last time I posted about them.

The ABS unit for a 2004 R1100S looks like the AM1 - repair cost runs around $900.

For the AM1, If you're reluctant to tearing out the hard brake lines , they will also be making a by-pass manifold w/electronics mounting plate soon.

Not sure what year or engine size the GS is.

Just another option for our bikes.
