OK so I am trying to do most of the routine maintenance myself. I am reasonably handy but this is the first time bleeding the brakes. Watched some videos, rear brake looks pretty easy so I give it a go. I don't have a Gs911 yet so I try the hold and release method and I get all the older(dark) fluid out and put in some fresh DOT 4. I go through about a third of a small container to make sure the fluid is running clear with no air bubbles. I am satisfied so I tighten everything up, make sure the level in the reservoir is good and make sure there is no brake fluid drips anywhere.

I spin the rear wheel and hit the brakes, they grab instantly. Perfect, no drag, great grab. I try it several times, perfect. Now I grab the front brake, the wheel keeps spinning? I did not change the front brake fluid yet. It seems that the brakes are not linked? I almost always use the front brakes exclusively, except for low speed stuff. I know its a bad habit. The bike is in "Road" mode so I thought the brakes are linked. I did have it in "Enduro" mode the other day but have since switched it back.

I didn't try spinning the rear wheel and squeezing the front brake before I started so now I am questioning if I messed something up, or if it was always this way?

Like normal

I just bleed the brakes like any other bike. The 911 only clears out the last tiny bit in the ABS module. The brakes are electronically activated, so I assume only actuates while underway.

I changed my brake fluid recently using the same method as you described. I had no issues.
Have you applied the front brake lever at full travel a number of times?
(and)
If you remove the filler cap, can you see any movement in the brake fluid?

A couple things about the linked braking system is that first the bike engine must be started for it to work at all and secondly only just about 10% braking braking force is sent to the rear and that is only if a good squeeze is applied.

Thx

Got it finished. Brake fluid front and rear, and final drive oil change. Now for the valve check:surprise: Thanks for the quick replies.

anybody have a torque setting for the bleeder nuts?

I am not due for a about 6 months, but the last time I did it, tightening down the bleeder nuts seemed a little squishy and I did not want to strip them.

Front Pressure?

The bike has to be running for the linked brakes to work. Both foot and hand levers have really good feel to them now. I am able to stop on a dime;)
