The 7mm allen key ones... I can't get them off! :bang: Any advice?

Turning them the right way?

Use an allen socket and hit it. They should be tight and usually more tight than you can achieve with a standard allen key.

Aint got one of them, just the old allen keys, looks like another trip to the shop! They just wont budge

Get a set of allen keys that yuo can use with a socket then use a power bar works every time!Either that or a long piece of pipe into the back of the allen key save you going to the shop

i have a caliper bolt key (allen key with posh handle) that it strong enough to stick a 3 foot bar on, and then you get enough leverage to crack them off.

as with all bolts that have been seized in by heat, they'll suddenly crack off and then you'll thump something hard with your rapidly moving fist if you arent careful (ouch)

It's off due to the ade of a pipe Thanks folks.

Now the disc is being a pain to get off too! First time doing this though, I'm enjoying it

You got the caliper and caliper holder off? The disc won't come off until you have removed the 2x 17mm bolts from behind it. Then you need to stop the disc turning as you remove the 2x 12mm locating bolts. I find sticking a screwdriver through a bolt hole stops it turning

Then if it's still stuck give it a whack with a soft mallet

P.s. remember not to breathe any of the dust in.

The two at the front and two at the back are off, it's just very stuck! Giving it a hammer hasn't helped much either, bit stumped atm

a rubber mallet of hope and glory should sort it out.

That's that wheel done, new problemo, other side now, the nut with the weird end on the front of the brake disc will not come out, it's just rounding :'( Any tips??

if you cant get some mole grips on, its grinder time (dont be afraid)

I've never seen bolts like them before, can they be relpaced with normal flat head ones or will I have to get the same style? And where could I get them?

Or get yourself a little vice - just a 3inch job should do. Clamp it onto what's left of the straight edge and it should make short work of those pesky 12mm bolts.

What are you trying to take them off with? I only ever use a 6 sided long reach socket. 12 sided sockets or ring spanners just mangle them.

They're there to help with aliging the road wheel with the bolt holes. You could use standard bolts or get some from a scrap yard. They're pretty much the same across the whole Fiat range.

This is pissing me off now. Dad is going to get a tool which he thinks will help for tommorow, fingers crossed it will because I have to get it to Stockton by thursday for timing belt!

Can you explain the gridning method? Will that not just leave the centre of the screw inside and impossible to get out?

Gaz

i mean grind the head off, reomve whaterer the bolt was holding in place, and then get some mole grips on the remaining part of the bolt to get it off.

maybe i misunderstand which bolt you mean, can you post a pic?

You do mean the ones that hold the disc to the hub yes? at 12 and 6 o'clock of the hub nut in the below photo?

Oh and say hello to Barry and Paul for me new crank position sensor working fine

thats the bolts i was thinking about. i had to grind one off on a arosa just a few weeks ago, those bolts get very hot, which seizes them in place. if you replace them you should use copper grease, it makes life much easier next time.

It's out now, I was working at it for an hour or so and no movement, I go down an hour later for one last try and it just came right off.

Cheers for help folks

strange, perhaps they had cooled down or something. Either that or you ate your wheatabix.
