Review on 🔧 Copap Brake Fluid Bleeder with 4 Master Cylinder Brake Bleeder Adapters - 90 to 120 PSI for Enhanced SEO by Randy Brimmer

This vent valve did not work as expected in practice. The master cylinder reservoir is too tall to fit under the open hood. The big problem is that the master cylinder is located near the hood on most cars, so this is a common problem for most users. The height of the bottle is too high to fit in the space between the open hood and the master cylinder. I had to top up brake fluid manually instead of automatically keeping it full. The bottle needs to be short and wide to function as intended. Vacuum generation is negligible and requires a lot of air to operate. You need a decent air compressor. Air is sucked in along the threads of the bleed screw, making it difficult to tell when all the air has been removed. TIP: I smeared brake oil around the bleeder threads and it improved the situation. I ended up pumping out the old fashioned way when the second person pressed the brake pedal. I just wasn't sure if the brakes were fully bled, otherwise
