Front Left Caliper Help

Hi guys,

Think my front left caliper is duff - when bleeding, having cracked the nipple, fluid leaks out at the base of the nipple rather than down the bleed tube. Have tried different nipples but same result. Is it worth trying the teflon tape trick or do I just risk a used caliper - are the 4 pot Tokicos fitted to any other bikes to improve my Ebay search options (GSR600 etc)?

Need two new tyres and caliper for MOT so trying to save pennies but need brakes sorting as a priority as can't bleed them like this.

I'm so unlucky that if there is such a thing as re-incarnation I'll come back as me!

Thats unusual ..... You are only cracking the nipple by 1/3 of a turn ? Thats really all you need.
Anymore than that then, because it is a slightly tapered hole, it will bleed out then.....

Otherwise, it kind of indicates a crack or fissure.....but, that is fairly unlikely.....

Teflon tape is not going to help, as brake fluid disolves PTFE (Teflon), i am not aware of ANY type of sealant, liquid or tape, that will work.....

I might no' be a smart man Jenny....but i can pain' ma copper colored bike a dif'ren color.....

Thanks amte, I suspect a crack or thread damage from a previous owner perhaps forcing the wrong size nipple in? Either way it looks fooked as if I barely crack it nothing comes out, opening it slightly further (not even 1/3 turn) results in fluid leaking around the nipple and down off the caliper to the disc and then to the floor.

I'm so unlucky that if there is such a thing as re-incarnation I'll come back as me!

As long as you can bleed it, then just go with that and save the money on another caliper...

I wonder if J-B Weld could be used here. What do you think?

Another option is to check into using a Helicoil to repair those threads.

I often use an aerobic thread sealant.
I use just a drop, and let it cure. Works great to keep fluid from working its way up threads while using the bleeder.

I think the couple I have/use are Three Bond products.

Anaerobics are like common thread lockers. You take the air away from them and they cure. When you thread the bolt in, it takes the oxygen away and they set. Have any of you ever noticed that the tubes are not even close to full!? This keeps air in the container so the agent does not cure.

Aerobic sealants you dab on and let them sit out in air to cure. Then thread them in. Lots of factory Kawasaki bolts come this way in the bags.
