I am trying to install the disc brake swap front disc brake kit. All was well until i tried to install the grease seal on the back of the rotor. I ruined both seals that came with the kit. Can anyone tell me how to correctly install them?

 

i tap them home with a rubber mallet or a block of wood and a regular hammer

 

I actually used a roll of electrical tape and a deadblow hammer. Block of wood works well too, though

 

thanks for the help
