Pump It Down....EASY
I didn't read all the posts (a lot), so someone might have said it already but, I used a copper washer from a brake caliper hose to caliper fitting washer on mine. It's a perfect fit. Some may like a lighter or firmer feel, so you'll have to make washer adjustments, (thickness) but works great & it was free cause' I had the washers lying around.
It is time consuming doing this mod, but well worth it.
