Home Made Brake Pressure Bleeder & Universal Master Cylinder Adaptor

Hey Guys,
This is my home made Brake Pressure Bleeder & a Universal Master Cylinder Adaptor I put together.
Hope You Like it,
Cheers.

A good vid, thank you. I've used something similar, but with brake fluid in the spray bottle. Starting with the fluid level in the brake fluid reservoir (BFR) a little below the max imum level the pressurized spray bottle would pump brake fluid into the BFR increasing the fluid level in it. Also, the pressure of the air that was in the BFR would be increased. Bleeding fluid from the brake system resulted in the fluid level in the BFR being maintained due to the pressure in the spray bottle transferring more brake fluid. On completion of bleeding and releasing the pressure from the spray bottle, the residual pressure in the BFR would return fluid from the transfer hose back into the spray bottle. I never had a problem with the BFR being overfilled and a mess everywhere. The level in the BFR would be virtually the same as when the operation started since the BFR still contained the same volume of air as at the beginning. Of course, this system requires an airtight seal on top of the BFR, otherwise air can be lost and the BFR overfilled.

I have long done the same thing with vacuum on the bottle at the wheel, have to keep the master full

Thanks for your great idea, this is fantastic I'm gonna make one for myself. Great video by the way.
Cheers Astro

Good video. I use a garden sprayer to reverse bleed brake systems. I force the fluid back through the system from the caliper/wheel cylinder into the master cylinder. It can get messy if the old fluid isn't removed from the master cylinder and one forgets to depressurize the sprayer before removing the hose from the bleeder.

I made one of these years ago when I needed to bleed the system on my 65 MGB. No fancy dual circuit brakes on this old girl. Just four lines radiating out from the union on the right side of the car. I found this worked great without pumping it out too much, usually just a pound or two of pressure was enough to flush all the dirt out of the lines. I need to flush my 2010 Charger now, so I guess it's time to make up another one. Thanks to the OP for posting up such an awesome video.

Add a tee and a plug to adapter plate and a elbow pointing up for the air. Then you can add fluid with out removing the adapter plate. Use 1/4 tee. Add fluid with a
squirt type oil can. Use the set up to blow out the system when changing out your fluid.
