Review on 🔧 Capri Tools CP21029 Brake Vacuum Bleeder by James Lighting

I have used this on 3 cars and 2 bikes. My *first* impression of it was that it was mediocre. As others have pointed out, it tends to pull air around the bleed screw threads and it always seemed to me that it was letting air back into the calipers. But today I think I discovered the magic of changing the oil on a Honda CBR. 600r. First, I cranked the air compressor up to 40psi (the recommended minimum). This prevented air from being sucked in around the bleed screw threads. Second, I pulled and locked the trigger to create a vacuum for about 5 seconds before breaking the bleed screw. So I don't think air can get back into the caliper. Also, I closed the release screw before releasing the trigger. This means it will run a little slower due to the low PSI. I'm a home mechanic so it doesn't matter and is even beneficial on bikes with tiny tanks. It's a little annoying on my truck. With my limited experience I think this is a pretty good product if you follow my advice.
