The recent thread about impact wrenches got me thinking...

I need to change the rotors on my Honda Oddessy. They have 2 large
phillips head screws countersunk into the rotors which have to be
removed before the rotors will come off.

I don't know if they are the original rotors (70K on the van, I've had
it since 40K with the same rotors) but I'm thinking that with all the
heat generated by braking, they might not be the easiest screws to
remove.

I didn't want to try backing out the screws with a huge phillips head
driver for fear of damaging them, then having to drill them out, etc.

Before I take everything apart (again) does anybody have any thoughts
on the best way to remove the screws, assuming a big screw driver
doesn't work?
2 words: impact driver

Absolutely. Just had to do this on my son's Kia. Took about 5 seconds
to conclude that a normal phillips was completely useless. Then I
remembered that when my FIL died several years ago one thing I inherited
was a hand impact driver.

Murphy's law was not enforced that day so I actually found the darn thing
(having never used it prior to that) and it took three blows on one screw
and only one on the other. Had a hell of a time getting the second screw
separated from the drive head though.

While on the topic, WHAT are the engineers thinking in this application?
Wouldn't a torx, square drive, or just about anything be better suited to
such an application compared to a phillips head?


I'm not sure why they're even required. One would think a simple
indexing pin would suffice.
