GS-911 bleed test on 02 K1200LT always red bars
« on: March 07, 2023, 10:52:38 AM »
Hello all

I'm trying to successfully perform a bleed test on my 02 K1200LT with FTE iABS (K1X) after flushing and bleeding the wheel and control circuits. I've got BMW's workshop manual for the K1200LT and did everything completely according to the instructions. No matter how hard I pull the lever and push the pedal it's not possible to achieve higher pressures than around 126 bar for both the front and the rear control circuit. So the bars stay always red and the tool say "values not within range". After a 2nd time bleeding both control circuits the values did not change at all.

What am I doing wrong? Does anybody know what pressures have to be achieved to get green bars? Thank you in advance.

Hello

the pressure should be in the range of 140 bar.
New brake pads could be the cause
Brake lever adjustment to maximum
Move the brake lever briefly to inflate
Then build up maximum pressure.
