Annual Help (alternator and brake line)

[billsheila]

Guys;
N2131X is in for annual and a few items cropping up. Need some advice.
1) rear alternator. Mechanic says seal is shot. He took it out and is scratching his head on how to change the seal, having never before taken a skymaster alternator apart. Next idea is to send it to a specialist shop to have the seal done and alternator checked and cleaned (of oil) at the same time. He says "brushes don't look good". As far as I know this alt was changed when engine was changed by prior owner (only about 250 hours). What do you think I should do? I was thinking to send it to the shop but make sure they will "repair on condition" the alt and not just do a full rebuild for nothing. What do you think of bad looking brushes at 250 hours? Note my plane is a 1965 will the (only) 30 amp alternators.

2) brake line swivel joints. Seems I may have one bad swivel joint, but he is still diagnosing. I know I have read prior posts on this either here or on CPA website, but I can't seem to find them. My recollection is that they can be rebuilt, but then I also recall some folks saying don't bother...but new ones are Cessna crazy prices. If someone has more information on these or can point me to prior posts, I would really appreciate the help.

Thanks in advance for any help provided.
