+1 on the SOLDER advice...crimping is a shit way of doing things, they do fail and give u higher resistance

I have 9000klm on a BT020 with still another 2 to 3000 left on it

I disagree. If you've kept everything clean, and the seals are in perfect condition, there is nothing wrong with re-installing them. Especially at such low mileage. Lubricate the seals & pistons liberally with clean brake fluid when re-assembling & you should be fine. Check for leaks when you're finished bleeding. Also, piston seals will not "blow out" on hard braking. They may leak, but won't fail catastrophically due to their design. Please don't ask me to ride your bike, I value my life!

Hi Dawg...Mate I've been a mechanic for 25 years and the only way I'd re-use piston seals was if I was in the middle of Aust and had to do it to get home...I'd wait, fit new ones as if a seal lets go under hard braking into a corner your gunna end up cannon fodder mate!
