Capri Tools CP21029 Professional Vacuum Brake Bleeder Kit - Automotive Brake System Maintenance Tool for DIY & Mechanics | Perfect for Car, Truck & Motorcycle Brake Service

OK, so I received a defective unit yet I still rate it 5 stars...WHY???Because this thing is awesome! First one I ordered was trashed during shipping... with the air port sticking out of a hole the box when it arrived. NO THANKS! I decided to return that one because I figured it was probably damaged somehow by the idiots also called UPS. Second one I bought was in better shape when it arrived, so I used that one. Like others said in their negative comments, it does pull air in to the rubber bleeder adapter, but so what. It still pulls plenty of fluid, and there is NO way any of that air is getting in the caliper. You would need a negative pressure in the lines for that to happen, and this thing is always pulling a vacuum when activated. I did have two other issues though, but again, it worked so well that it still gets 5 stars. First issue is that after using continually for about 10-15 minutes, it started spitting and sputtering from the exhaust and the vacuum stopped. I had to let it sit for a few minutes and then tried it again. It then worked for a minute or two and then started spitting and sputtering again. Was barely able to finish the second caliper because of this. NOW, this may be caused by water in my air line or maybe not... I do not know what the cause. After a few days I tried again and it worked fine. I do have a line drier installed but it may not be working well enough for a continuous compressor run. This thing pulls a pretty awesome vacuum at 120 psi, but obviously your compressor will have a harder time keeping up, as mine barely did. Second problem is that mine leaked brake fluid from the vacuum port on the lid while in use. Not sure if the fitting in the lid was not installed tightly, but it did leak fluid onto the lid when in use. I did not see a way to tighten the fitting, as I was unable to remove the lid to check the underside. Did not leak a ton, but in my opinion, it should not leak at all. SO... in the end, I returned it because of that. In spite of the leak and spitting/sputtering issues, I absolutely will buy another when I need it. This thing is hands down AWESOME, and easily allows a 1 man bleed job. The fluid pull is slow enough that you can lock on the handle and stand at the reservoir to keep it topped off. Add a little extra above the max fill line, and by the time you get back to the caliper to tighten the bleed screw, your reservoir is right where it needs to be - and the job is done. I bled all 4 calipers on a 2008 Mitsu Lancer with the spongiest brakes I ever felt, and the pedal is now ROCK SOLID!!! Thank you Capri Tools! Again, I will absolutely buy another... hopefully one that does not leak.
