as title, i cant get the screw that holds the disc off or the caliper.

any tips? i have tryed WD40, i think these haven't been off the car ever which is a 1998 polo.

might have to drill the screw out, they're buggers for seizing in. Don't worry about not having the screw all it does is hold the disc in place while you put the wheel on, can just make it a bit awkward to put the wheel on. If it bothers you, you can drill and tap another hole further round the hub. Or if you drill a thin hole down the old screw thread you might be able to get it out and re-tap the same hole.

You want an impact driver for the disc screw, they're quite soft though so you may end up having to replace them afterwards. Failing that any screwdriver that has a shaft running all the way through the handle so you can smack it with a hammer should do the trick.

For the caliper bolts, assuming it's the allen key headed bolts you need to undo, it's alot easier if you use an allen key attachement for a ratchet.

hmm jus another idea....hav you tryed gettin more leaverage on it e.g putting a bar of some sort on the end?? may be wrong

A breaker bar on a bolt that size is likely to do more harm than good. Only M10's IIRC

Turn the disc so that screw is as close to the brake caliper as possible. Now curl your four fingertips round the disc on the opposite side. Now give the disc a swift pull toward you..

What you've just done is use the disc as leverage to pull at the head of the screw,stretching it slightly,and thus releasing its grip on the disc.

It will now be easy to undo.

In the event of it still being seized,do it again a little harder,and when you place the screwdriver in the screw,give the handle a tap with a hammer to shock the thread loose - you're basically releasing all the pressures from the screw before you try and turn it.

i will try this later today sounds like a good idea, does anyone know where i can get new screws from becasue the ones on just now are a bit worn.

I used to try little tricks of "easing" them out. Always led to knackered screws taking ages to get out.

I always replace bolts and screws with new ones anyway so it doesn't bother me if I knacker them.

I use a Sledge hammer held in one hand or heavy mallet now to bash a well fitting screwdriver at the screw. A few whacks and it will free it. This method has yet to fail me.

VW dealers can order you in just about any screw or bolt you need. GSF stores can also get these bolts.

looks like this is next on the list to try casue I've completely ruined the screw.

do you actually have to turn the screwdriver or just hit it really hard?

I find heating stuff up witha blowtorch normally helps when they are seized ...

I just bash the screwdriver into the screw, then press firmly on the screwdriver and turn it out by hand.

It works best to shock the screw but it has saved me before in a case of rounded screw to create a new grip.

a good way of releasing a stubborn screw is by bashing the centre of the brake disc with a large copper mallet

LOL, you can use a sledge hammer with one hand?

i gave up in the end and payed £35 to get a garage to do it becasue i didnt have the tools to the job, they also welded up my exhaust aswell so the price wasnt to bad.

Just hold it close to the head and use it like a mallet.
