Brake Pressure Bleeder - Easy

[tubeman]

Pressure bleeding your hydraulic brakes is the way to go. It makes it a one man operation. No pedal pumping, no back flow. I constructed an easy rig that can use a compressor or a pump sprayer. Chedck it out! Comments please!

Whole rig.

It is my understanding that this method can destroy the ABS module on "some" cars. Just be careful.

instead of using the air compressor directly- Use a secondary reservoir with brake fluid or
put brake fluid into the pump sprayer and connect to your adapter- that way you have enough fluid to bleed or flush your entire system-
"same as motive"

Interesting concept....

I just use speed bleeders myself.

if anyone is interested I have a comercial version of that available for sale

I made a pressure bleeder from a cheap garden sprayer. You only need around 10 psi. The direct connection to a compressor seems like a great way to damage something and make a big mess if you are not extremely careful.

I use a regulater set at 25 psi. I basically got the idea from the motive but it was so messy. This way I can do it without spilling a drop.

Yep that's it. Same idea. Thanks!

The fluid is too expensive to do it that way and I find I only need about .5 liter to do the whole system. So all I do is top off the resevoir a couple times while bleeding and I don't waste a drop. At $15/half liter for Motul I can't spill any!

Unless you have a VERY good compressor filter/water remover, I would be leery of using my air compressor on my brake system.

Air compressor tanks condense a lot of moisture out of the air.

Exactly! You want the moisture OUT of the air. The pump sprayers don't wring out any moisture. The moisture is in the comp. tank where it gets drained out. Any compressor will remove moisture good or not. That's why they all have drains.
