Hello hello

I was looking at my brakes and found that on the right hand rear drum one of the screws has sheared off so I can't get it off, this slightly disconcerts me as there's been an odd knocking noise coming from that brake and I wanted to check it and fit new pads if required.

Anyhoo sorry waffled there, basically I was wondering if there was any way I could get the screw out without going to a garage as I haven't taken the Winchester to one yet for repairs and I'd rather not give up the air of smug satisfaction which comes with this

Thank you I await your all encompassing knowledge.

If this is one of the screws that holds the drum on- just drill the countersunk head carefully off. The drum should then pull off with the brake adjustment backed off. There is another hole to screw a retaining screw from the drum into hub.

If you do mean 'sheared off' then it wouldn't prevent the drum removal! .
If you actually mean that it has stripped the thread so will not unscrew you could be lucky with apply a lever to press the drum outwards whilst
applying an unscrewing motion to the offending item. DO NOT be tempted to hit the drum with a metal hammer!

Dear Sir,

(sorry, couldn't rsist that)

You need some tools:-

1) twist drill (electirc is easier - cordless is handier)
2) set of good quality high speed metal drill bits (I've found the ones with the "pimple" end really good for not slipping - so's an electronic speed control on the power drill)
3) set of stud extractors (with a "T" bar or wrench) - left hand tapering thread in machine steel

Method
Soak the offending article with penetrating oil

Choose a drill that will fit inside the screw diameter.
Clean the head and if necessary centrepunch the offending article
Drill carefully into the screw.
Insert stud extractor until it is fixed in the hole.
Attach wrench to extractor and unscrew .

Or, you can choose a large drill bit and remove the top of the screw completely - John's suggestion.

Once the drum is off you can use a pipe wrench (or similar) to remove the dead bit of the screw.

The screws only jkepp the drum on the hub when the wheel's taken off - normally the drum is held in place by the road-wheel nuts. The screws don't have to be done up exceptionally tightly!

Depending on how bad it is, I'd hammer a screwdriver into it and simply undo it. One of those "hit through" types comes in very handy, I've got a large cross head that bites most larger (door latches, brake screws and suchlike) screws unless they're completely rounded, and if that's the case I've got a selection of smaller flat head ones that often manage to chisel enough of a groove in the screw head to undo it. The hitting the hell out of it approach really helps break the "lock" holding the screw in, so they wind out nice and easily too

Yes, the screws are brass, so soft enough to deal with. Like it said above after I drilled the head off, there was enough of the screw protruding from the hub to grab with mole grips (vise wrench, grip wrench) and undo it. New ones available from the usual suppliers for a few pence.

Brass ? Not any of mine!

Nor mine

nor mine

Maybe someone put gearbox cover screws in my cars drums then!

So, shall we all guess as to what happened next?

Hello! sorry I intended to post back but have had a job on with a ridiculous deadline which has eaten my time away for the past two weeks.

I got the brake drum off with a bit off levering and gave it all a clean, the knocking has stopped and I have a couple more cuts and bruises to add to my proudly battered hands.

thanks for the advice
