#4673571 - 02/21/18 05:19 PM Another Brake Fluid Flush Question

Iíve lost track of how many one-man brake fluid flush videos and DIY tutorials Iíve watched and read. I always use my Vacula but wonder if there is a better, easier way. Eric the Car Guy has a video where he pumps the brake pedal while fluid is expelled through a plastic tube into a bottle. I always wondered why air isnít sucked into the system past the bleeder threads when the brake pedal is released. I certainly see a lot of air bubbles in the fluid when I use my Vacula. The way I learned as a kid was you have a partner who works the brake pedal. You open the bleeder on the down stroke but close the bleeder before the pedal is released. Question: can one person pump the brake pedal with the bleeder valve open? This would certainly make the job easier. Thanks.

Here is what I use although I rigged it to operate with a mechanical vacuum pump instead of an air compressor.

Yes, it can be done. I routinely do one-man bleeding. You crack open the bleeder screw about a half turn. This allows fluid to flow out under pressure and releasing the brake pedal lets only a tiny amount to be slurped back in... kind of a poor man`s one-way valve. Keeping a tube on the bleeder screw makes sure no air is slurped back in.

Gravity bleeding can work, too.

(Embedded images preview isn't working for me lately)

Perhaps more versatile, and almost certainly more reliable than your Vacula, which is way overkill for non-pro use. Good name though.

But its only 0.5% of the cost, so its not going to fly on bitog.

IF it sucks air (you can pull or push fluid, or cycle between them) if you hold the syringe higher then the bleed screw the bubbles will rise into it.

What about air sucked in past the bleeder threads?

My own home made one man brake bleeder. I bought the 3/8" O.D. - 1/4" I.D hose at an ACE Hardware and used a quart drinking bottle.

Honestly I was skeptical of the one man bleeder system. So I decided to try it out. I made the bleeder as shown on youtube. Hooked it up and cracked open the bleeder valve. Pressed on the pedal several times and and checked the fluid level. Found on my vehicle I can pump the brake pedal a dozen times before needing to refill fluid level. It did work. I do it this way all the time now. Wife is much happier not having to be the brake buddy.

Tip for first time bleeders: You will empty the brake fluid reservoir faster bleeding the front brakes vs the rear brakes on most vehicles.

No experience using wives for this, but I've tested Scottish and Taiwanese girlfriends in this role. Neither were very reliable, and they are probably also the most expensive solution on the market.

You need two things for the 1 man bottle tool to work:
1) correct ID rubber hose. use a small hose clamp to seal if anal.
2) fluid present inside the bottle covering the lowest level of the hose

#1 helps minimize risk of air bubbles making it through the hose/nipple connection.
#2 makes it so there's no air, but rather fluid coming back up the hose when you let off the brake pedal. After a few cycles, any residual air in the tube from the start has been pushed through and the hose is pure fluid. The tiny bit of old fluid that gets pulled back up by letting off the pedal is nil and not enough to be a concern. Just keep cycling the fluid.

This is the machine that works. This is how I have been bleeding my brakes for decades

If a gravity bleed doesn't work. There is a leak sucking in air. It proves your work when replacing lines.

It doesn't really matter, the master cylinder is above the bleed screw, it has not option other than to drip out. You are right about it sometimes taking a longer time but eventually it will.
On those I usually just give the brake pedal a light touch to get it moving.

When installing new calipers I always remove the bleeders first and put a couple of turns of thread tape on them and put them back in without bottoming. This seals the threads and once bled and tightened prevents the screw for seizing later.
