Orion Motor Tech Pressure Bleeder, 2.5L Pressure Brake Bleeder Set with 49.5mm Adapter, 2.6qt Manual Power Brake Bleeder with 500mL Brake Bleeder Bottle Compatible with GM Models Chevrolet Chrysler

Word of advise. The seal for the pressure cap that goes on the master cylinder, if the seal has a rough look to it then it has to be flipped around, the other side is smooth and thats the sealing side. Otherwise it will leak brake fluid all over. Mine came with the rough side facing the sealing side and it would not seal on the master cylinder reserviour, after flipping the seal its worked like a dream. But overall I can't complain about this, it makes bleeding and flushing brakes a breeze. I pump it up to 15psi and open the first bleeder. Another tip, when bleeding the last caliper start bleeding it until the air is out of the clear drain hose attached to the bleeder, then releave the pressure in the main bottle, pump the brake predal 5 or 6 times, disconnect the quick release from the cap and pump the brake pedal until the fluid is at the MAX line. If you do it in those steps it will not draw air back into the system and you will have a mess free brake bleed/flush process.

I don't know if it truly matters, but I didn't fill with fluid. Replaced all the lines on my truck and had already mostly bled the brakes using vacuum. But as always... I was sucking air around the bleeders. Overfilled the reservoir and used this pressure bleeder to force it through. As with any other brake job, I kept an eye on the reservoir and topped off as necessary. After I had a good pedal, I opened a bleeder until the level was at the full line only wasting a little fluid.If I was doing a large job from the beginning I would follow normal protocol and put the fluid directly in the device. However, no clean up.Tip for anyone really struggling, I read on another review (can't remember if it was on this product or another) that you can pressure bleed from the bleeder up into the master. Apparently helps with removing trapped air bubbles in the master. This was done on a clutch. Not sure what modification you'd need to do this, but it's worth having stored away if nothing else does it.

The media could not be loaded. Air leak at the cap and so won't pressurize on my Chevrolet Volt. I emailed the company, they were very responsive, and sent another one right away. However the second one also leaks. And yes, I made sure the gasket had a smooth side facing out. I even flipped it, but had the same result.Surprisingly, the supervisor who answered my second email then said I ordered the wrong one and only offered 15% refund, suggesting I try to resell the item myself! I'm grateful that Amazon has such easy returns because apparently the company has a skimpy policy themselves.

I built my own bleeder before but this set was cheap enough to justify buying pre-built. Pressure bleeding is the way to go with a one-man brake job. Very easy to remove air, and do a complete fluid change. I change fluid ideally every 3 years in my personal vehicles. The pump is very easy to use and seems to be well built, it does take quite a few pumps to get it into action though. For a newer product to market the build quality is very nice. I wish they would have chosen to have a separate cap to add fluid not just the pump opening. There is also no bleeder valve on this model you have to unscrew the pump to bleed the pressure. Overall I like the unit and the shortcomings didn't really affect the performance at all, and also didn't make the job any harder or dirtier than it needs to be. Overall I think this company was MOTIVated to make a competitor to a popular brand and I think they pulled it off in spades. I for one prefer the quick disconnect style adapters to the other kind.

In my case the adapter at the master cylinder reservoir did not seal. It puked fluid everywhere with little if any pressure added. I'm going to have to figure out how to make a seal from an inner tube or sheet of rubber. The quality of everything else looks ok. Just can't make use of it yet

This thing saved me a lot of frustration. I’ve used larger more expensive units at old jobs and had similar attributes this tool had. All for a fraction of the cost. Was struggling to get brakes bled on a 2009 Silverado 2500. Needed the pressure bleeder to go through the bleeder procedure with a scan tool. This did the trick!

why not give thicker gasket ?
