I found 2 older threads on this but they were closed so couldn't resurrect them.
I just finished a lower leg service on my Rebas and on first compression the wiper seal from the damper side popped out. Since this was the damper side I can only guess there was too much oil in the lowers causing less space for air to compress under the wiper seal. I put in 15ml in each lower leg but there probably was some oil that didn't drain out. So I stripped them down again and put the seal back in place. This time when putting oil in the lowers (10ml this time) i compressed the forks a little before tightening the bolts to relieve any unwanted pressure. At full compression the seal stayed in place and they seem ok again.
Does this sound right or have i made a silly mistake somewhere?
