205 bleed nipple

[Paul (7)]

Anyone know what size spanner I need to undo this with? 10mm is too big, so is it 8 or 9mm.

Would I be wasting my time using anything other than a specialist brake spanner? From personal experience, what's the likelihood of them shearing off (20%, 50%)?

I'm renewing the brake fluid. Presumably, I only need to get one on each diagonal circuit to undo.

Any tips (including maybe, use a garage) welcome.

Model is a 1.4 GR 1992

If they're the same as mine they'll be 7mm on the front and 8mm on the back, you can undo them with any old round spanner. They shouldnt shear off unless you whack them with a hammer or something, but dont overdo it if they wont go, as if they do shear off you'll need to replace the whole caliper or get it drilled out.

If you're going to do it, do it properly you wont be able to bleed it properly unless you can undo all the nipples, also if you want to get it done dead quick, invest in a pneumatic bleed kit (not expensive), especially if you plan on doing it by yourself.

It's certainly not worth getting a garage to do it if you feel like doing it yourself! Shouldn't take you more than an hour or two at most.

Cheers

Thanks Andy,

I already have an Eazibleed pressure kit and have checked that it includes the correct size cap. I've used it on a couple of other cars before, but I've done a Google and read some horror stories where the nipple's sheared off.

Ah well, if it shears off while you're undoing it then it'd shear off for a garage too I've seen them missing before but I dont know whether that was from over zealous tightening or just road debris knocking them off... as long as you just do them up so they stop leaking there shouldnt be a problem.

When I had to do mine, both of the front nipples sheared off (without the use of excessive force) = Two new calipers... The materials Pug used for the caliper and the nipple seem to bond chemically after a while, although I had bled the system only about 12 months previously.

According to the chap at the motor factors, this was the most common reason for people buying recon calipers!

Same for me and I had put some copper grease on the threads about a year before.
