2004 R1150RT: iABS points, Bubbles within the Funnel software…

Greetings all. First up, apologies for the lengthy intro and clarification, however I wished some recommendation on the iABS (Built-in ABS) on my 2004 R1150RT, with 50,000 miles. Recommendation on the strategy I’ve used and what to do subsequent a lot appreciated…

The issue is that as I try to do the ABS Brake Bleed on the entrance (after finishing the rear) – I’ve bubbles within the Bleed/Flush Funnel !! In case you are intrigued, or need to provide recommendation, please learn on and let me know what you assume…

I lately went to go for a journey, preparing for an extended journey and my Brake warning lights got here on, each of them!! I wasn’t removed from house, and pulled over and did the same old begin sequence. After a mile, identical factor. Not eager to tempt destiny, I repeated this train as I slowly made my manner house.

After studying these boards, and because it was due a service, and had been sitting for some time, I figured I’d observe the directions (right here and elsewhere) on bleeding the brakes and altering the fluids (it has been about 3 – 4 years since final accomplished, and hardly any miles (for a lot of causes) have been placed on the bike within the 3 – 4 years.

So after a go to to the Boneyard, I purchased the Servo Help Brake Bleed/Flush Funnel Device, and another stuff to do a full service (4 x spark plugs, oil filter, air filter, engine oil, gear oil, alternator drive belt, and so forth.. I had just a few issues to assist with the precise bleeding (the tubing, non-return valve, and a reservoir).

After eradicating the fairing and gasoline tank, despite the fact that I had each warning lights – the service on the rear ABS brake bleeding went simply because it ought to. (Be aware: This was simply the ABS Brake bleed, not the the Management Circuits, I used to be going to do these after finishing the Entrance ABS Brake Bleed…)

So, onto the entrance ABS Brake bleed. After eradicating the left & proper entrance brake calipers, eradicating the pads, inserting appropriate picket blocks towards the pistons, I used to be prepared!! I put in the the brake bleed equipment (with non-return valve and a few fluid in it) onto the nonetheless closed left bleed valve…. On the ABS unit I eliminated the entrance ABS Brake screw and inserted the funnel in place.

Now the enjoyable begins… After I poured within the Dot 4 Brake fluid and turned on the ignition – I observed Bubbles!! These carried on for a bit, so I turned the ignition off… After they stopped, and I turned on the ignition and squeezed the entrance brake lever – extra bubbles… This carried on for some time. I ultimately figured – what the heck, why not open the brake bleeder and see if bubble come on the market and which may assist pace up the method.

The consequence was just about the identical, Very sluggish, small quantities of fluid popping out, and infrequently just a few small bubbles (I might se the fluid transferring slowly, and the bubble transferring barely extra quickly). I used to be undecided if the bubble have been from the ABS unit, or attainable leaking in from the threads of the bleed valve. The fluid within the funnel ultimately drained decrease, to the purpose the place I might take away the funnel

Then, with it sealed once more, I eliminated my bleed tube from the bleed valve, and put some PVC tape (plumbers tape) across the valve threads, put it again in, and repeated the method. identical consequence. Gradual regular stream of bubble showing within the funnel, occasional bubbles within the tube as much as the non-return valve after opening the valve. I feel there would possibly nonetheless be some air getting in via the tape and threads inflicting these bubbles.

The brake fluid popping out (albeit slowly) is darkish, and exhibiting it is age…

Different signs to notice: The “Basic” warning mild (decrease pink mild) is sometimes off after just a few seconds (appropriately), and more often than not has stayed on. The ABS Warning Gentle (high pink mild) is flashing quickly (round 4 occasions a second…). The Servo’s don’t begin making noise till the entrance brake lever is squeezed. Then they run repeatedly, till the ignition is turned off, and I repeat the cycle once more. Upon beginning once more, the servos usually are not operating, till I squeeze…

Aside from a brand new/alternative ABS unit, I used to be pondering of getting a brand new totally charged battery (present one is exhibiting and holding a full cost however is about 5 years previous). I’ve not checked any relays or fuses, however the whole lot is working (lights, horn, flip indicators, starter motor…). The brake traces are all unique, and would possibly profit from being changed by a set of Spiegler brake traces.

I’ve simply ordered the complete set of Pace Bleeder valves for my yr and mannequin. As soon as these are put in, I’d count on that I’ll have eliminated the potential of air getting again into the ABS/Brake traces, or exhibiting up within the pipe to the non-return valve.

In case you have learn this far – any ideas or recommendations could be most gratefully (and gracefully) obtained. Cheers, Adrian
