I am trying to change the front brake fluid on a 06 LT. Just installed Speed Bleeders and using a vacuum pump and Paul Sayegh DVD.
Everything goes fine until I crack open the bleeder. Very little fluid comes out. tried it the old way with the brake lever with the same result. Is the ABS my problem and should I find a Dealer.

CCR here we come brakes or no brakes.

If you did not have the key on you will get no fluid out of the calipers. Vaccum pump will not work here use the ABS pumps to push the fluid out. There are two separate circuits and the wheel circuit runs fluid out of the reservoirs on the ABS pump to the calipers. The fluid from the handle bar reservoir only goes to the ABS unit as a control signal. Look in the "Files" "Technical" area for Mark's article on integral brakes and my addendum for the 05 and up on the change in reservoir locations.

I should have my brake flush video ready by CCR this year if you can wait until then.

Hi John, I re-read your addendum. Very good points. I've just added a note to remind me that the inboard (1) reservoir is larger due to the increase volume of fluid required for the front brakes. 2 callipers verses 1 on the rear.
Last year I had my brake system bled (control and wheel circuits) at the dealer. Lucky for me they let me help them and I picked up a few tips.
The BMW reservoir tool they had did not fit my '06, something about not having an adaptor for that frame. I could see what they meant as a straight screw in fitting to the ABS reservoir would contact the frame. That was good in a way as the wheel circuits were bled using just a large syringe, something easy to have in the garage. Usual care about not letting the level drop too far and getting air into the system. There were three of us doing this job, I was operating the brake lever, just lightly, so the ABS was not delivering full pressure, and so not emptying its reservoir too quickly. One to undo the bleeders OEM and one to replenish the ABS. Worked fine although we were careful. Front / back similar.
Now the control circuits which were done first. The front first from the bar lever and then the back from the foot lever.
We undid the front brake master cylinder and using the syringe emptied the fluid. Just rotated the handle bars full, didn't worry about loosening the grip and rotating the reservoir. Filled with new fluid and then using a very slow pumping action the tech loosened the bled screws on the ABS, with a clear hose to clear the old fluid.
Thats where my memory gets hazy. There was a required order they were bled and I don't remember. I do remember the sequence was repeated several times, both for the front and rear control circuits. Guess I should have written this down. I do recall the last bled point was on the brake line above the ABS motor. Needed some type of an adaptor to fit
the OEM fitting.
If anyone can shed light on the correct sequence to bleed the control circuits on the ABS that would be much appreciated.
Looking forward to your video
Cheers

There is a sequence but that has been relegated to bleeding only now and no longer required for the flush. Just take fluid from the tall bleeder point on the ABS unit. There was a bulletin that changed that. I never got much contaminated fluid out of the other ports so I agree with the change. That last one was a fill adapter that they pulled fluid from. Again not necessary for a flush but required for a bleed after air has been introduced. The only item reqired for that fill adapter is a short 10mm bleeder. I bought one for the front calipers on the early bikes (Brembo calipers) and it works fine.


The Beemer Bone Yard funnel will fit IF you cut it about 1 inch above the fitting and put a short section of Tygon tubing (or any similar plastic tubing). That makes the funnel flexible and gets around the frame.

Thanks John, just the tall ones, makes sense.

If the two short inboard bleeds are for the cross over internal ports, presumably used for residual braking or to activate the interlinked function, fluid volume there would be minimal.
That just leaves the two short bleeds next to each tall bleed.
What is their function ?
Are they just to bleed out air if introduced accidentally ?
If this is the case in what sequence ?
Logically any air bubbles would rise to the highest point, ie the taller bleeds, but that sounds too simple.

" There was a bulletin that changed that. I never got much contaminated fluid out of the other ports so I agree with the change. "

Any chance to a link / copy to that bulletin ? My service was done in Jan 2009, so the dealer was either unaware of the change or it came out later.

Sorry for all the questions, guess inquiring minds just need to know. :)

I'll look into obtaining some Tygon tubing, thanks again for the tip.

Cheers

Did you finish the brake flush video? I don't recall seeing anything further on it, but I will be doing this for the first time this winter and would love to see the video first.

Yes I did finish it and it turned out pretty large. I got the 99-2004 on one DVD and the 05 + on a second DVD. I had it showing at CCR and had copies for sale at the silent auction. I guess I need to figure out a way to distribute here for the rest of the gang.

OK OK I knew this was going to happen and I should have been better prepared.


My real job has me pretty strapped right now but I will look at duping a batch this weekend to ship out. And look at shipping costs.

I think ball park is $25 with the 5 covering shipping and materials and the 20 going to CCR charity for CCR 2011 in Boise. Please specify which year group you want 1. 99-2004 or 2. 2005+. I will do my best to get these out and paypal may be the way to pay. Details to follow in a few days. Look for a new post and I will add everyone from this one to the new post.

Hi John,

I'd also like a copy of the CD for my 2002 LT, I'd appreciate it if you add me to your list. Paypal works for me.

thanks

Sorry, John, I didn't mean to start something! I just remembered your mention a while back of the video that you were working on and was wondering what happened to it given they my 24K is just around the corner.
