Hello All! This is my first post to this forum so please bear with me. I'm replacing the brake seals on my Case 410 gas tractor. I've got 2 replacement seals, part #A32015. The housings I've got have two seals per side. I've read some posts here which say to use two seals per side and one which said that only one per side is needed. If you've done it with only one per side did it work out fine, or should I go with two per side? I also don't know which way the seals should be oriented. If I use two should they be oriented the same way or in opposite directions? I'm also going to have to adjust the shims under the housings, since these aren't the originals. Any suggestions on how to do that will be much appreciated.
