Motive Power Bleeder

With the suction type you can go from wheel to wheel and leave the master cap off . Put the hose on loosen the bleeder , Tighten it and move to the next wheel.

Look in the master and top it off as is required. No pressure in the system. The only place fluid comes out is at the bleeder your doing. And its sucking fluid which cannot spray like a pressure style. Easiest and safest one person method available.

I have seen the pressure style make a real mess when mistakenly taking the master lid off under pressure. Talk about paint damage. Like a small explosion of fluid.
