Simpson Posted June 1, 2009 Report Share Posted June 1, 2009 Basically I trusted some people to take care of my RB and its kinda blown up in my face and come back with a raped bleed hole, where water i just pissing out the sides of the bolt... what are my options... so far I have thought of 3 options. - f**k it off... I've got a spare 04 lever body so can just put the RB lever in there and be done with it. - Try and use a treadlock when doing the bolt up hoping it will just help to seal the gap? then bleed the rb through the piston, which is hasstle but oh well. - Try to arildite it shut? Will this stand up to the back pressure? Quote Link to comment Share on other sites More sharing options...
Connor Powell Posted June 1, 2009 Report Share Posted June 1, 2009 (edited) Tried Ptfe tape?http://www.tapes-direct.co.uk/index.php?ma...csjvklksqimce25Being 28p its worth a shot, in case you don't know what it is, Ptfe tape is used by plumbers to wrap around the threads to stop them leaking, Do this to the bleed bolt and i recon it will work.

Ash-Kennard Posted June 1, 2009 Report Share Posted June 1, 2009 go find a balloon. put the bleed bolt into the hole with the balloon in between i have no idea if that will work. could be fun trying though Quote Link to comment Share on other sites More sharing options...
bigamac Posted June 1, 2009 Report Share Posted June 1, 2009 Option 1. easiest.Who messed it up? Quote Link to comment Share on other sites More sharing options...
Mikee Posted June 1, 2009 Report Share Posted June 1, 2009 Tried Ptfe tape?I was about to say that.There is also some kind of silicon (forgotton it's name, mabye a plumber on here could help) that plumbers use to make the threaded ends of radiators more water tight. I don't know what kind of pressure it would with stand though. Quote Link to comment Share on other sites More sharing options...

Connor Powell Posted June 1, 2009 Report Share Posted June 1, 2009 Problem with that is that the end of the radiators threads match, Simps's problem is that the whole that the bleed screw has been made bigger so the putty might not work, With ptfe tape you can wrap more on to the thread to keep it tight, if you see what i mean Quote Link to comment Share on other sites More sharing options...

I work with a plumber when he need's abit of help and he uses both the ptfe tape and the silicone stuff, he told me why he does it but I can't remember, so I was going to suggest that you try both together If just the tape on it's own fails.

Guest Posted June 1, 2009 Report Share Posted June 1, 2009 (edited) The tape (mentioned above) is really good, it partailly stopped my crank arm from coming loose so a tiny bolt will be fine.... I think.Edit: 0.55 Edited June 1, 2009 by Nick pyke :) Quote Link to comment Share on other sites More sharing options...
liam-pantera Posted June 1, 2009 Report Share Posted June 1, 2009 i think your best option is to tap the bleed hole out very carefully and use a larger grub screw because they are available , good luck . Quote Link to comment Share on other sites More sharing options...
Simpson Posted June 1, 2009 Author Report Share Posted June 1, 2009 Where are they available then? Quote Link to comment Share on other sites More sharing options...
Heatsink Posted June 1, 2009 Report Share Posted June 1, 2009 Defo give the PTFE tape a try first. Potentially a cheap and quick fix. Hydraulic brakes are low pressure so it may work.Otherwise, Loctite 577 is the thread sealant I would use (works for higher pressure set-ups and you'll still be able to get the bleed screw out when you need to), although not worth buying just for one job since it will cost around £15 for a bottle!Steve Quote Link to comment Share on other sites More sharing options...

Rob Leech Posted June 1, 2009 Report Share Posted June 1, 2009 have they just lost the ball bearing that sits inside ? If they have, get 1 out an old freewheel, fit a treat .Josh.have they just lost the ball bearing that sits inside ? If they have, get 1 out an old freewheel, fit a treat .Josh.Acctually, not sure if they come with a ball bearing, might well of been a bodge , so try wackin a ball bearing in there, will give you a perfect seal aslong as its clean.Josh.Oh, and if this works, make sure to take a few out with you, 'because if you bleed your brake when your out nd about, your gauranteed to loose the lil thing .

forteh Posted June 1, 2009 Report Share Posted June 1, 2009 Yeah theyre meant to have a ball bearing in there, if its missing then thats probably the reason its leaking. Other than that they havent cracked the body by trying to tighten the bleed screw up too much have they? Quote Link to comment Share on other sites More sharing options...

Connor Powell Posted June 1, 2009 Report Share Posted June 1, 2009 No bodys not cracked... ball bearing? Bingo!Problem solved, theres meant to be a ball bearing sat behind the Grub screw, thats why it be leaking like a siv. Quote Link to comment Share on other sites More sharing options...
forteh Posted June 1, 2009 Report Share Posted June 1, 2009 Yeah, its about 2-3mm diameter and acts a seat for the grubscrew to seal against. Stick one in there and it will seal again. If youre stuck for the size Ill take mine out and measure ti for you Quote Link to comment Share on other sites More sharing options...
