I am rebuilding my front calipers. The damn dust boosts seem impossible to get on so they seal inside the caliper and also on the piston.

Is there a trick to getting it into both grooves?

 

yes very ez with two people and a 90 degree pick. this is how I do it. first put the o ring seal in. then seat the dust boot into the grove in the caliper. make shore its in the groove all the way around. pull on it a little to make shore its in. then put some brake fluid on the piston and place on side of the piston in the boot and use a pick to work the boot around onto the piston. ez if u have another seat of hands to help keep the boot from popping off

 

Ok yeah 2 people seems to be the trick. Could work it around while making sure boot didn't pop off. Pain!
