Removing Front Brake Rotor On 2006 Silverado

New to this site and just saw the "Ask the Tech" forum. I'm trying to replace the front brake rotors on a 2006 Silverado 1500. Rotors are frozen on and I've tried penetrating lubricant and beating with hammer, but won't budge. What are the 3 small holes in the face of the rotor for? Are these for pulling the rotor off the hub? One of these has a #30 torx screw in it. Funny thing is I didn't think about the holes until my wife pointed out after I spent 2 hours cussing at the darn thing.

 

Also, my new Power Stop cross-drilled rotors do not have these holes.

 

Thanks.

Remove the screw. It is only there to hold the rotor on during manufacturing process.

I removed the torx screw. Any clue what are the other two holes are for? If not, any suggestions for removing the frozen rotor.

I use PB Blaster to get things loose. Are you getting the liquid around the hub where the rotor meets it in the center. You could always try applying heat to the rotor while tapping it.

For those wondering the two threaded holes are for a 3/8-16 (coarse thread) bolt. When threaded into the hole it will hit against the hub and eventually pop the rotor off. Continue to ratchet the bolt until you hear the rust cracking. You will need to brace the rotor with a pry bar wedged into the rotor fins so that it stays stationary while you are cranking the bolt down. Use a grade 5 or SS bolt so that it doesn't gall up or bust the head off because you have to really crank hard on it.

I always apply some never seize between hub and rotor when installing new rotors. In fact my mini cooper, which I purchased new, had never seize from the factory.

What this guy said. Stick a bolt in each hole, and crank each one down a little bit at a time. Eventually it'll press the rotor off of the hub (Had to do this on a co-worker's Altima the other day).

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
