I was wondering, Brake bleeding.

I have a monojet syringe like thing to blast goo out from where you get a tooth pulled.

Waht I was wondering (since I remenber someone saying something about it) if I could use it to help bleed the front brakes on my bike.

I dont want to really go through 10 hours of bleeding again.

Think it will work? or someone also said Turkey Baster too but cant remember?

just run a hose from each bleeder valve to a can and let them gravity bleed for a while as long as the end of the hoses are under brake fluid you dont have to worry about air getting in the line just keep the mastercylinder topped off.goodluck,happy wrenching

This may be really late but, huh, never too late to ask?

I've never bled brakes before and that doesn't sound too difficult. So, I just run a tube from the caliper into a can and let the fluid drain - while keeping the other end topped off? Thats it? How quickly does the fluid drain? How often would I have to top off the master cylinder.

Any advice?

Thank You!!!!

Have some fluid in the can so air will not get sucked back in. If you let reservoir go to low you will have to start all over again so check frequently. The syringe will allow you to quickly suck new fluid thru system but will drain reservoir just as quck. Bleeding brakes can be a long drawn out process.

Bench bleed them if you really want to get the air out and you don't have a high volume power bleeder. By putting them on a bench, you won't have to fight gravity. The air goes sideways instead of being forced down, where it doesn't want to go.

On a car, the vertical distance from master to caliper is usually less than on a bike, so a bike can be tougher than a car.

I always run a tube from the bleeder valve back into the reservoir then slowly pump the brakes. This way it keeps sending the fluid back eliminating the need to constantly top off the reservoir. The air escapes as the fluid goes back into the reservoir and after about 10 or so pumps there is no air in the system at all.

Main thing to remember doing it this way is to make sure no fluid spits out and gets on the paint job so covering the tank with some old towels or a plastic bag is a good idea.

Good idea, Wicked, but I would caution against that until all of the old fluid is purged from the system. Even though I cleaned everything as best as I could, those first several pumps were very nasty.

Wireman's tip of having the free end of the hose connected to the bleeder valve under brake fluid is the critical difference. Once I did that, bleeding worked easily. It is also the recommended way from HelUSA , the manufacturer of my new brake lines.

I use a sqeeze type ketchup bottle and force the fluid up from the caliper. First I drain it all put to make sure that there isn't any old crappy fluid left, then I put a piece of battery tube on the tip of the bottle (not the bottle you but it in, but a Rubbermaid type with a pointed tip) and force it back up from the bottom (caliper bleed valve)The tip of the bottle is kind of mushroomed, so I use a ziptie to keep the tube attached to the bottle.
