Broken brake bleed nipple!

Hubby has just broken one of the rear bleed nipples off our T25 and is in a bit of a quandry about what needs to be done to fix it.

Does anyone know ?

Will it need drilling out? If so, how do we get at it to do that? What recommendations then for retapping and stopping?
Is it easier to just replace the cyclinder? If so, how easy are they to get hold of?

This is all a bit of a pain as we sold our other form of transport yesterday and are 2 miles from the nearest Autofactors - so trying to minimise the number of cycling miles required!!

All help gratefully received.

Tallbird,
Eurocarparts price for a (Dansk) wheel cylinder is only £5.50.

Look here

I would tend to go that way, and work on the nipple at your leisure.
An 'easy out' (stud extractor) or even the tang of a file will sometimes succeed but they can be obstinate, depends on your luck.
German Swedish and French or Just Kampers are other places to look, but 2 miles each way on the push bike will do you some good!

I did the same on mine, I used and easiout stud/bolt remover (you can get from motor factors/Halfords etc) to get at mine but I tend to agree with others that replacing cylinder is probably as cheap and quick

If the bleed nipple is broken buy a new cylinder as indicated above - and you should replace BOTH cylinders. Don't skimp. Theres a good rule of thumb with brakes:

"If in doubt, throw it out" - never was this more true of braking components.

You can mess about with engine components but don't try to extract bleed nipples. Its possible to do it but who wants to risk small shards of metal in the braking system? As a mechanic in formative years I'd often get owners asking how much the braking system was going to cost to which I always replied "How long is a piece of string?". Its just one area of a vehicle that should not be compromised. For a bleed nipple to break off shows lack of maintenance in this area (ie why not coat nipples in light grease when first put in etc) and its far wiser to start with fresh cylinders and rule out any potential failure later on.

Over the years I've seen owners spend a fortune on high performance carbs, bigger engines and so forth and for some reason brakes don't even come into the equation. Fact is, its the one area that HAS to be perfect since they can invariably save your life - and indeed those who may cross your path. Need I say more?
