Default Brake Bleeder Kit

I think I?ve found the Holy Grail in Brake bleeder kits all for less than $10.
While at Lowes I stumbled across this 2 Liter (0.5 gallon) Pressure sprayer for $5.88 in the home and garden section. While there, I went and bought 10 feet of 3/8 OD tubing (1/4? ID) ~ $3.00

Connect the 3/8? tubing (about 2 feet) to the sprayer and the other end to about 2 feet of ?? ?static? line tubing. Wire tie them together to prevent any leaks. Connect the static line ?? tube to the zerk brake fitting (AKA bleeder valve) and you have bleeder kit that works with virtually NO spillage. Just a couple of drops when removing the tube from the brake (zerk fitting). I filled up the Left Main on my 10 in less than 5 minutes.

I cannot find a listing at the Lowes website but here is the manufactures info.

That 1/4" static line segment was the missing link for me - had the 1/4" ID tubing attached to my dedicated sprayer and found it was too large to snug onto the bleeder nipple. Was going to buy new barb and tubing to correct the issue, but I have nylon static tubing in abundance here in the shop.

Problem hopefully solved and staying solved.

Ok so this is a totally stupid question, but the zerk brake fitting.....I never in my life would have thought that the end of a bleeder was the same size as a zerk, but it is????? So any zerk grease filler fitting (a new one of course) will work?

Yes - simple zerk as far as I know.

I have a similar set up using a hand operated oil pump. Same concept.

One addition I made is scavenged a grease pump end fitting and threaded a barb into it for the hose. The grease gun fitting is a simple housing with rubber “spring” that holds two ball bearings to close off the fitting, one in and one out. This allows you to pump fluid into the hose to fill the hose. Under pressure, the air will bleed out and you stop when fluid just starts to come out. The ball bearings then close off the tube. Then you can plug it into the brake fitting.
This is how a grease gun keeps its extension full of grease so you don’t pump air into the fitting. Works the same with brake fluid.

This isn’t important unless you are servicing your system and don’t want to drain all of the existing fluid. For a new system full of air anyway, it doesn’t matter.

This also works well if you want to scavenge out old fluid and replace with new, which I do every brake pad change. Again, eliminates the mess of draining the old fluid into a pan.

Anyway, just another idea.

Remember - only fill you’re reservioir about 3/4 full or it will expand at temperature and run down your fire wall or on your shoes!

Default Brake Bleeder

Didn't find the 2-liter version at Lowes but found a 48 oz. Multi-Purpose Hand Sprayer at Home Depot. They appear to be one in the same except for the pot volume. Same brand, different model number.

Default Simple

That looks like a good solution and better/reasonable than many options. I have a couple of dumb questions....

I couldn't tell how you connected the 3/8 and the 1/4" lines. The ID and OD are the same so I can see how it would sleeve in but did you just put safety wire to hold it?

Where did you get the fitting that connects to the zerk? I see that you safetied it.

Do you use aviation brake fluid?

Thanks for the 101 level questions.

John,

(1) I connected the 3/8" tube to the sprayer nozzle & safety wired in place. This fitting easily come off and just as easy goes back on.

(2) I inserted the 1/4" tube into the 3/8" tube, wrapped the connection with electrical tape & safety wired this connection. This is only to keep the lines connected and keep from dripping brake fluid all over the place. Remember the lines will be under pressure. The pressure will depend on how may "pumps" you fill the bottle with. I didn't go over board just enough positive pressure to go force the fluid to go up hill, through the lines.

No special fitting to connect to the bleeder valve. Just "HOLD IN PLACE" the 1/4" line. It's a snug fit, but it can & probably will come off if you don't hang onto it.

I used 5606 hydraulic fluid.

Hope this helps.

john

Default Compatability

Just curious if the brake fluid is compatible with the plastic of the sprayer.
I wish I could find a stainless steel sprayer, my dad had one but long gone now.
