6mm Bolt Stuck in Front Rotor

[myxr]

Just gave up. The threads on our 5mm bolt holding the front rotor on is completely seized. We've stripped the allen head after heating up the bolt so it's toast and I'll need to go to my local dealer for a new one. Can anyone recommend where to go from here. Drilling and tapping seems to be the obvious answer but I don't have the tools or experience. At least the other 3 wheels went ok but I'm discouraged to say the least!

drill the head of the bolt off to get the rotor out. try and leave some of the shaft of the bolt left so after you get the rotor off, you can get some vise grips on if and try to work it out. other than that,an easy-out, just dont know how well it will work on that small of a bolt

Thanks Downhiller. I've done this on less critical projects (non-car related) and it's probably the best route to start with. I'll get a new bolt from my local dealer and match the drill bit size and see how it goes. This bolt serves very little purpose. I wonder if it would really be a problem if it was ground flush and not even used? That is, if it doesn't budge

i know with chevys and some fords, they use those bolts just to hold the rotor on so the caliper sides on nice and smooth and centered. but since we have bolts instead of studs, this bolt keeps everything aligned so we dont have to turn the rotor, align the rim, and hope and pray we can get the first lug to hold everything in line so the other 3 go in fine

Success! I started with a sharp 3/8" drill bit, taped to a depth just below the head. Removed rotor, applied some liquid wrench, taped on it a few times and then used the vise grips. Done!

My 16 year old and I have just completed our first complete brake job. Price of car: $1650. New exhaust and center support bearing: $1190 (at a shop) New brakes: $210. Our next project is the NiCad batteries and thanks to this site, It looks pretty straight forward. Looking forward to all the gauges working! :thumbup:
