Brake line washers: safe to reuse?

In the matter of brake line crush washers - ask yourself a simple question: Is it worth injury or death (to say nothing of resulting damage to your bike) to have brake system failure for the want and use of $0.10-0.65 parts? You've just spent $50-250 on new brake lines, bought new race-spec brake fluid (or just generic DOT whatever), can you really say that you couldn't find the money for new sealing washers for the banjo bolt fittings? Really?

Motorcycle shops don't patch tires anymore due to liability issues, not real technical function issues. Some techs just hate the job in general anyways.

Relating to oil drain/fill plugs' sealing rings/washers, if you don't mind an occasional leak / total oil loss from your engines (i.e. when the sealing ring fails and the drain plug vibrates out as a result), and really want to save that $0.25-1.00 per oil change, go right ahead.

I'd bet that there isn't a single motorcyclist that can't manage to allocate their discretionary spending such that they can always afford new sealing rings/washers for their maintenance.

Then again, WTF do I know about maintenance anyways...

I'm completely surprised that a BMW owner would have this attitude... I bet that you park your bike if it has 3000 miles on it and you don't have an oil filter. Hey to each his own... man people accuse me of getting all fired up over stupid shit!
