Part # for brake caliper bolts?

EPC is throwing a certificate error for me (on two separate computers), and I've searched exhaustively here, so if anybody happens to know where I might be able to find this P#, it would be much appreciated.

Also, any recommendations for reverse screw extractors to pull out a stripped caliper bolt?

Are you looking for the caliper bolt that bolts it on to the knuckle? If you are looking for the skinny bolts that hold it together, they are not available as a spare part as they are not meant to be disassembled. Maybe you can source it direct from the manufacturer of the caliper.

Well... crap. The one that attaches it to the knuckle/hub loosened up just fine with some PB Blaster, but one of the Torx got stripped on the last of the eight bolts that I thought held the caliper in place.

Am I missing something? Do you not even have to touch those eight T50s to change the rotors/pads? Maybe I should search for a brake change DIY thread... color me embarrassed.

Where did you find it? Yea you don't have to remove those bolts to change the pads.

I need to change the rotors and pads, but I was derping on how to get the calipers off. Slapped myself a few times upside the head, regained my common sense, and figured it out

If you separated the torx bolts that holds the caliper halves together, you may have just messed up your calipers. Most people have trouble with them leaking after that.

I got all but one bolt out, but the last one stripped, so I just put the rest back in. Currently have the caliper off and it's solid as a rock, so I hope it's alright. I'll definitely look out for leakage, though.

Any tips on getting the T30 out that holds the rotor onto the hub? Hit it with PB Blaster and I've been trying to carefully loosen it, but it's near impossible to get any torque on it with the rotor spinning.

Use a hammer; you may need an "impact" to break it loose. Or try using an impact wrench on very low torque; careful not to strip it....

The **** rotors that I let my shop install last time are made up of nearly as much rust as metal now, so the bolt inevitably stripped, just using hand tools after PB Blaster and banging on it with a hammer. I'm heading out tomorrow to buy two new ones for the new rotors, and a reverse screw extractor.

Lesson learned - don't use cheap *** rotors, even if your shop tells you they're the greatest thing since sliced bread. They were Zimmermans, if I'm not mistaken. Less than 40k miles and just over a year - the Akebono pads are still around 50%...
