Bleed nipple seized and snapped off

[rk8479]

Bleed nipple on rear brake snapped off and rest is seized in the caliper, i have got a banjo with bleed nipple inside that and after bleeding the brakes a few times the brake works but only if the pedal is pushed all the way down and it only gives a slight brake effort, im guessing the air up in the little hole to go into the old bleed nipple has air inside, what should be used to plug it? i was thinking of epoxy resin but im unsure

Hold your caliper so that the bleed nipple is highest and push the pistons back in. Any air should be expelled with the oil.

Hi , I take it your on about using the epoxy on the outside of the caliper - I hope - in the bleed screw opening ?
There's no need , it's the bottom of the screw that shuts the air/fluid off , any air trapped will be inside the caliper. There is a way of bleeding it using the banjo but it would either have to be at the top of the caliper or turn the caliper so it is making sure that the pads stay with the disc between them.

The best and only proper way forward is to drill the rest of the bleed screw out yourself / get it done or a new caliper.

Yeah, and i ment use the epoxy or something similar inside the caliper to cover the hole towards the bleed nipple so no air can get up there to be trapped before bleeding

[cresad]

No , No , No don't put anything like that inside the caliper , you could loose all braking. It's either repair or replace .

Get a spare caliper and refurb it, or get a refurbed one. See if they'll take yours as an exchange, but be sure to explain the situation, they won't return your deposit if they're expecting a sound caliper.

If they won't, get a spare caliper outright and then see about drilling the bleed nipple out of yours and refurbing it. Always handy to have a spare that you can refurb off the bike in your own time without making the bike unusable.

Another vote for replace caliper. Does piss about with brakes, do it properly.

[andys675]

if the bleed nipple broke off without moving then a banjo bolt bleed nipple will be fine, if you've had the fluid system open then you must push the pistons behind the pads all the way into the caliper before you start bleeding the brakes or it will take forever or just won't work

Yup, both of Pete's replies are spot on as usual. No need to do anything as drastic as replace the caliper - you only need to bleed the air out.

Why don't you just drill it out? As far as snapped bolts are concerned it's probably one of the easiest to do provided you don't go too deep. It's even got a pre drilled pilot hole.
