bleeding brakes

[DAN82SED]

i decided to bleed the brakes on my 300tdi this evening, all was going smooth until i was on the last corner and discovered the bolt part of the bleed screw was shered off no ive got no way of undoing it to bleed it! any ideas guys???

Acquire a new bleed nipple, and then set about carefully removing the old one.

cheers luke, goona pick up a new nipple tomorrow, but how am i going to remove the damaged one? ive tryed every size spanner and socket to loosen it but no luck

[LandyManLuke]

If its rounded, rather than sheared, you could file two flats on to it so an adjustable or smaller spanner can be used, or you could try tapping on a smaller socket.

If it's sheared flush then you're in to the realms of drilling it out, eazi-outs, etc.

thanks agin luke, the nipple is fine but the nut shered off around it. filing it down sounds like that might work, will give it a go tomorrow,

give it a go with some mole grips should be easier than filing and you wont get metal shavings everywhere

I prefer a big pair of water pump pliers (i.e. 15" items) as i find these grip better than vice grips.

Or, weld a nut on it then undo with a spanner. The heat will help. Just don't go crazy or you'll bugger your seals up.
