Not necessarily. As a pressure sprayer, it has an inlet tube that goes to the base of the sprayer. If you filled the sprayer with fluid prior to pressurization, you'd be using hydraulic pressure as opposed to pneumatic to clear out the brake lines. It would take a lot of fluid to make sure everything was flushed clean, but this would certainly keep the resevoir from being empty. > Message: 15 > Date: Tue, 16 Apr 2002 14:18:20 -0000 > From: "jtrealtywebspannet" <jtrealty@xxxx> > Subject: Re: Pressure Bleeder > > The biggest problem with your method is you can too easily empty the > master cylinder and to refill you must constantly relieve the > pressure and refill.
