I bought new brakes for my e30. I did the fronts and the rear left with no problems...Now the rear right has a stripped bolt..the allen head thats holds the rotor on..

1. How can i get it off? I have that canadian tire stripped bolt remover kit or w.e the **** its called but i've never used it and don't wanna mess it up even more.

2. Once it's off...where can i buy a new one?

Oh the dreaded stripped hex bolt issue... ;)

Jack it up, remove the caliper and the caliper mounting bracket. Take a big hammer and whack it off... (rubber mallet if you like the disc, metal if you're changing the discs); the top of the bolt will shear off... then heat the part of the hub slightly... (only slightly) then twist it out with vise grips.

Cheers.

New bolts you can get from the dealer... I bought some not too long ago. Can't remember exactly what they charged, but it was less than $1 ea.

you can also use a large drill bit and drill most of the head off. When most of the way through, use the hammer method as dice said. It will come off a lit easier. But don't use any small drill bits as you will want as much of the shank of the screw left over to put vise grips on after the rotor is off.

The reason it strips in the first place is because people tighten it down like it holds the car together. DON'T REEF IT DOWN. its not necessary- just make it snug enough to hold the rotor down. the wheel bolts will do the rest. good luck.

For the old one, just take a drill bit and drill the head off. When the rotor is out you can easily grab it with vise grip, maybe heat up the hub with a plumbing torch (yellow cannister is better). When reinstalling it, use NeverSeize paste, worth it's weight in gold (or silver) when you go to attack it again.

center punch and a hammer, keep tapping it to the left to loose it.

or drill it out if that fails.

New bolts came with my brembo blanks, but im sure you get get them almost anywhere.

that's the best way than just get vise grips and and undo it

lol where were you yesterday?


well i took it off...but i didn't get a chance to get a new bolt, dealership closed at 4:30 yesterday and i got too much school shit to do today.

can i use any bolt, as long as the diameter is the same?
i'm pretty sure I can find one in the garage that'll fit, i don't feel like driving up to maranello for one bolt.

Thanks for the help guys

bud, you aren't driving a Chevy... replace with the proper bolt. Do you think the next guy who's possibly gonna buy your car is going to take you seriously when you red neck the job???
