Help!!! Brake disc screw stuck

AlexYW

I was just changing front brake pads and discs, everything was going fine, then the got to the last screw on the left disc, and it just won't budge! Even worst the hex head hole is starting to get mashed up and turning into a round hole!?
Anyone know what I can do? I can't go to a garage cuz my car is up on axle stands and I don't have any fancy tools like a airgun.

That happened to me mate so as I was replacing disks anyway I just cut the head out with a grinder

I've had to drill the head off the hex screw before when fitting new discs.

is this the screw that lines up the holes for the hub ?

drill the head off like matt said then mole grips or leave the stub in it won't hurt not being there the wheel bolts will pull the disc into place

I got it of!!!! So happy! 🙂 I used a chisel type screwdriver and hammered a groove in the screw head, then with the screwdriver in the groove hammered down in the direction that it screws off, and slowly but surely it started to turn. Only problem now is I need a new screw, looks like a bike ride to the scrap yard tomorrow morning 🙁Oh well, thanks for the help anyway guys.(y)

Don't need a new screw mate the wheel will hold it once bolted back on. Mine hasn't got one and I've done 4000 miles like it

I removed the screw on my old 106 and my MK4 Astra, as I had to drill the head off them to remove the discs. As @[deleted] says, it will be fine when the wheel is back on, as the 5 bolts for the wheel hold it in place. It's just a location bolt that stops the disc spinning while the wheel is off.

Just one more problem, which way works best with grooved discs?

Matt

Pointing forward will last longer, but if you reverse them, they will be nosier and not last as long

It depends on the internal veins. If they are just straight (from centre to outside) then any way you want for looks.
Technically you want the grooves to wipe from inside of pad to outside of pad.

or just fit flat discs and still stop the same 🙂

Yeah but you can't beat the look of some drilled and grooved discs, always wanted some and its not like there that expensive either!

I used a slightly larger sized torx bit and hammered it into the allen screw managing to turn it with a t-bar, did no damage and was refitted.
Incidentally mine was also passenger side and if u think about it, it's the side usually in the gutter. Nice feeling when u get the little bugger out!
