I just did a rear brake job on my /05 ES330. Went great.
However, I am having a problem making sure the rubber protective seal sits properly sealed on the top caliper mounting pin.
I find that there is very little room to manouver. With other makes you normally shove the caliper into position and the seal pops back onto the lip on the sliding pin. In this case the seal won't go over the pin ridge.

I've tried gently pushing it with a blunt screwdriver with no luck. Eventually water and dirt will get in there. I'm sure there is just some knack that I'm missing here. Any tips?

Thanks!
