BradJohnson Posted March 11, 2013 Report Share Posted March 11, 2013 (edited) So I was low on funds, didn't have a bleed kit and was sick of taking my brakes off to bucket bleed. So I made this little contraption, What it is, is a length of brake hose with a barb in each end. One end is sealed to a generic sized bottle top using 2 washers and a nyloc nut. The idea is that a bottle of water will screw to the bottle top and the other end to the brake slave, you squeeze the bottle until the system is bled through and then tighten up your bleed screws. It works a treat and I have no air locks, and the kit doesn't leak! Props to Brad Tomlinson for the idea though!

Danny00135 Posted March 11, 2013 Report Share Posted March 11, 2013 surely setting an old inner tube valve on the top of the bottle and using a pump would be more effective... If you release the bottle it will just draw air back in when it expands :/ Quote Link to comment Share on other sites More sharing options...
dann2707 Posted March 11, 2013 Report Share Posted March 11, 2013 If you release the bottle it will just draw air back in when it expands :/ It shouldn't do? Like if you bleed from the slave to the lever. Squeeze the bottle to bleed the system, then nip up the grub screw in the lever, unscrew this bottle bleed kit then tighten the slave screw. If the lever grub screw is tight the bottle can't possibly suck air from anywhere if you get me? 1 Quote Link to comment Share on other sites More sharing options...

If the lever grub screw is tight the bottle can't possibly suck air from anywhere if you get me? The bottle looses water as it is compressed, the natural elasticity of the Polyethylene terephthalate will force the bottle to it's original shape, The water that this bottle looses will need to be replaced by air, and the only way of getting air through is through the brake system. Or am I thinking of this all wrong? Quote Link to comment Share on other sites More sharing options...
dann2707 Posted March 11, 2013 Report Share Posted March 11, 2013 I forgot the main point above. If you keep the bottle squeezed there is no chance of the air coming back in. Essentially, what you're describing is like using a syringe as normal, push the water through the system then withdraw the syringe so it pulls air back in, that's what you're thinking is going to happen yeah? But if you squeeze the bottle and don't let go then no air is going to be sucked back in. Quote Link to comment Share on other sites More sharing options...

Yes, but the adaption of a valve and pump will allow the water to be pushed through without having to keep the bottle compressed Quote Link to comment Share on other sites More sharing options...
BradJohnson Posted March 12, 2013 Author Report Share Posted March 12, 2013 Yeah a valve is my next project. I was thinking about adding one to this design but didn't have one spare. Quote Link to comment Share on other sites More sharing options...
