Review on 🔧 Capri Tools CP21029 Brake Vacuum Bleeder by Rob Parsons

Take other reviews of this product with caution. People complain about air bubbles being drawn in around the nipple and rubber bushing. It is true. So what? This is just a sign of a good vacuum cleaner. This air does not get into the braking system. It is drawn into a vacuum chamber from the outside of the caliper. I used this to vacuum the brake lines on a 30ft RV. It worked great, bubbles and all. I turned on the vacuum and then opened the nipple 1/2 turn while holding the vacuum line so it wouldn't slip off. I then went in and performed the old brake bleed procedure of checking the fluid level in the master cylinder. The RV has such a long run and lots of high air seats that you want to sit on. The vacuum combined with bleeding the brakes created enough flow to keep the air bubbles moving. I then went back and closed the nipple before stopping the vacuum. I went from soft, spongy, dangerous brakes to a hard pedal. I did it on my own with no help and didn't spill a drop of brake fluid. It took less than an hour from start to finish. I wish I had bought one of these years ago.
