I've read so many posts about the dreaded rotor screws that even I started thinking they were made out of some uber-indestructo-type material.
BAH & puh-lease.
Here's the deal on rotor screws. They are soft metal and not worth your concern. Not even a little bit. As in under five minutes per corner to rotor on the ground.
I approached mine knowing they were going to be stucker than shit. They didn't let me down either, laughing at my impact driver even (you can see indexing marks in the photos below, testament to that epic failure). I had classic screw removal bits, or drill bits that I could escalate to....
Well, no sense in screwing (chuckle...) around- directly to the 1/2 in drill bit, not new, but not abused either, and the ever classic battery drill.
As it turns out, this method is so quick I didn't apply more than a few token taps with the impact driver on the other three corners. From first picking up the drill bit to the fourth rotor being removed was about fifteen minutes. Including the time spent taking the pictures seen below.
Oh, and for the record, no, I didn't replace the screws.
1/2" drill bit > pot metal screws (lost one of them, darn it...)
Bit on screw- ya know, in case there was some confusion on this part...
Started- light touch on the drill till some of the head is removed. now that you have some meat to drill on you should lean into it a bit
In just a moment you'll find the top of the screw head on your bit
good sign, means your 75-80% done with that screw.
In the above pic you can see the ring in a new rotor, showing us there is just a bit of screw left to remove. Back to the drill we go...
"But..." you ask, "how do I know when to stop? How deep should I drill??"
Trust me, you'll know. The rotor is a significantly different material
. When the drill gets there it will sound different, feel different and the shavings will change from silver to dark gray. You will
notice the difference. On the first one, about the time you start thinking "Hmmmm... That's different" you should stop drilling. Your removing the screw, not shaving weight from the hub.
After a quick love tap from your favorite heavy, blunt object you end up with a freed rotor, easy peasy
Nifty thing about math, and rotor screws, is that when you remove thescrew head & the rotor, there is no more tension on the threads so they just spin right out into your hand... Kinda neat considering...
There ya have it-
Brake Rotor Screws - done.
No more mystery or confusion for all the folks who were dreading the prospect of replacing their rotors.
Try the screw driver
even try the impact driver if you have one
but don't hesitate to break out the drill.
- so easy to do I'd spend the money on a new drill bit before I bought an impact driver.
Drilling these eight screws takes only a few minutes
