Question for owners of Jabiru's with original brakes - I have an SP500 with the original braking system setup. As we all know the first Jabiru braking system is not known particularly for its slowing ability 🙂. In taxiing and landing roll out I find I'm able to manage this with throttle and careful control of approach speed. I do find however that on the last notch of the brake detent handle, the brakes won't hold the aircraft in run ups at anything more than 1600rpm. To take the engine up to 2000rpm I have to manually hold pressure on the brake handle. Not ideal.
I have replaced the brake cylinder o-rings, replaced the brake fluid and adjusted up the brake pad clearance. There is plenty of pressure at the handle. It just needs to be held on with more pressure than the brake detents will provide.
Is this everyone else's experience? I am wondering if there is another adjustment that I'm not aware of. I know there is of course the upgrade to the Mk3 brakes, but if there is another way to get some pressure out of my current brakes, that would be preferable.
TIA.
Ian
