Gas & Brakes

["Jon" <jwilliam@cyberzone.net>]

1. Reading through my Bentley and was wondering how many people 
were using premium gasoline rather than regular.  I get confused since 
there is more than one way to measure octane.  When the inside of my 
fuel door flap tells me I should be using 91 octane, and the pumps 
have a choice between 87, 89 and 93, should I be going with the 93 or 
am I wasting my money?

2. When I had my front end repairs done (on the car) my mechanic 
warned me that the front rotors were warped and that I would continue 
to get a shudder in the steering wheel when braking.  He assured me 
that it was not a safety issue but it's driving me ape-sh*t.  I'll be 
getting a hydraulic jack and stands this week and I'll have access to a 
second car to take the rotors to have them turned.  My question is 
when I force the calipers open to get at the rotors, will this necessitate 
me taking the top off the reservoir to avoid too much pressure on the 
brake line and will I have to bleed the lines before re-assembling 
everything?  Also, if anyone has a website or tips for this, please let 
me know, as I haven't done this before and figure that functioning 
brakes would be a good thing to have.  Searching the archives for 
"rotors" only yielded about 650 items and I'd rather not have to slog 
through all that.
