They are the tool you need for removing nuts or bolts that have rounded.

Then once you have got it out you can take it to compare to the ones in Halfords or to the fasteners to get replacements.

If they sheer however, you'll be buggered and will need new wheel cylinders -but they are not that expensive anyway. A motor factor may even stock the bolts if you have to get new cylinders. It's certainly not worth trying to drill the bolts out of cylinders for the cost of new cylinders.

Been upto Machine Mart in Croydon and got a set. Worked a treat for all but one that had perished so much its beyond help so will Dremel it off. But thanks, this saved me so much time this evening.

No probs, why won't they work on the last one then? Have you knocked the right sized one on with a hammer, then turned it? Doesn't matter if you sheer the bugger, just need it off!

You can always file edges to it again for the tool to fit on, even with persuasion, then it will grip into and undo it.
