| You have to take off the calliper, and turn it right way up. Thats the way it was designed. I doubt sucking it out will have enough flow to compensate for the speed at which air rises to the top of brake fluid.
What service did you have done. Because at 10000km/2 yr the fluids should have been changed. If not, best you be asking yourself how come there is air getting in there. Are your pads still Ok? Are you boiling the brake fluid from too much back brake use? Is one pad jammed on and heating it up. I think you need to seriously look at it, as you have a problem. |
