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 driverhttp://www.kk.org/cooltools/archives/000723.php
I'll look into it, but...

From the website...
"although it takes some skill to keep it on the bolt when you hammer
it."

And they seem to be talking about a socket over a bolt, not a bit in a
phillips head screw.

It's hard to tell the size of the screwdriver bolts from the pictures,
but none of them look big enough to fit securely in the large philips
head screws on my rotor.

I'll stop by Sears and see what they look like close up.

Thanks!

My wrench came from Sears many years ago.

"6 pc. impact driver set lets you free frozen or rusted screws. Each
hammer blow develops 200 ft. lb. of torque. Includes 1/2 in. sq. drive
tool, bit holder, 3/8 in. slotted and Nos. 2, 3 and 4 Phillips bits."

Same as this pic:

I have removed them many times and impact(same Sears set)is the way to
go. Often they only need a tap and comes out easy. But then...
