Hey, i was trying to put some new rotors on my car and the right rear caliper bolts (one of the two 14 mil ones) broke right the hell off!!!#$! I got the whole assembly out hub and all right now. I figured it was your standard broken off bolt, so I drilled it. 2 bits later I stuck the easy out in there and the usual. Ripped the threads right off my easy out! Same one had done some exhaust stud duty on my other car so I drilled the bolt again bigger and got a bigger easy out after it... rounded that one off too So far I've done 2 brake rotors... one I can't even get the rotor off cause of this stupid bolt. Broke 3 of those damned philips screws on the rotors themselves. This is what I get for buying a 20 year old beach car that sat in a mud hole for 2 years </rant>

Anyway to the important part...
Can I drive the car without the philips screws on the rotors until they come in? Also does ANYONE have some suggestions for this stuck bolt?? 1 more... wheres a good place to get these brake screws and bolts, the ones that did decide to come out look like ****. Thanks for any help

 

personally, you could just omit the phillips head screws and be fine. the sandwich between the wheel and hub will hold them in place fine. american cars have never used screws to hold the rotors to the hub and have never had problems.

 

Yes you can drive it just fine without those screws. I'd suggest you keep drilling that bolt out as large as you can before you start to near the threads of the hole, then see if you can't get a punch and collapse a side of it and just pull the remains out of the hole.

 

what do you all think about replacing the caliper bolts w/ grade 8s? I'd think a new grade 8 holds better than the white metal grade 10s that were on there anyways? I ask because I can get ahold of grade 8 bolts that will fit easily.

 

From your story, apparently the grade 10's 'hold' pretty well.

I personally wouldn't down grade bolt strength on a critical part such as the brakes. May be time for a trip to the wreckers, or a bolt supplier.
