You need to use it on some
brake system flushes but oh what a mess. Those standard adapters are
hard to fit, and prone to leaks and possibly onto the car's paint!
Because of these serious deficiencies most shops only use a pressure
bleeder as a last resort. They even pass up selling a needed brake
system flush because they don't want to deal with the mess. Well now you can sell the service with no leak worries - We have found the world's best brake adapters - based on a German idea- an expanding o-ring that locks in the brake master cylinder(reservoir)- Those flimsy plastic reservoirs now have a tight fitting adapter that still has an easy to
attach safety chain(with screw tension adapters). Now you can bleed
those domestic models and all Japanese models as easily as you do the few
European cars with the screw top ATA reservoirs.(We have separate
adapter for European cars).
