Hello,

I built my own pressure bleeder using a 1 gal sprayer, and plan to flush out my brake fluid this weekend with the new super blue stuff when it comes in.

The procedure for doing this seems simple enough, but one thing that is not clear is:

Do I add the new brake fluid to the 1 gal sprayer and pump the fluid through that?? Or do I add the fluid to the MC and then refill it when it starts to get low, only using the sprayer to pressurize the system??

Thanks!!

 

Yes...but that Super stuff needs to changed often because it attracts moisture and can rust your system. Dot 3-4 is the best. The brake system is set up to be gravity feed/bleed.

 

Sorry, your saying "yes- add fluid to the mc, AND use the sprayer to preassurize the system"--to paraphrase??

By often to you mean like every year or 2 years??

Thanks,
John

 

I'm not a fan of the home pressure tanks bleeders as you may notice because i have seen the problems that can occure like sending air in the system. Did your pressure tank come with instructions? ...many apply air pressure only. Changing fluid every 2 years is about right for normal use.

 

To be honest I have not heard of any issues like this. It seems to me the only way you could get air in the system is by letting the MC reservoir go empty??

The tank was designed as a sprayer, so one would fill it with the desired medium to spray, pump it up, then spray with the provided wand.

As it is now, I can either add the fluid to the tank, then push the fluid through the sprayer to the MC reservoir and out the caliper, OR I can simply use the sprayer to put air pressure on the system, periodically having to stop, and refill the MC reservoir.

So, the question is: WHICH WAY DO I DO THIS?

 

Sorry if this has been asked/answered a million times already. I just want to make sure I do things right. I am still very much a shade tree mechanic, so I learn as I go.

Your help is greatly appreciated.

 

I just power bled my brakes today with a homemade power brake bleeder made from a Hudson type sprayer. Fill the sprayer with brake fluid (about 3 qts) and then pressurize the sprayer. This will push pressurized brake fluid through the master cylinder through the brake lines and out the bleeders.

Start by sucking the old fluid out of the master cylinder with a turkey baster. Then fill the master cylinder with new fluid then attach the power bleeder with brake fluid and pressurize the system. Start with the rear right, then rear left then front right lastly front left. You want to start with the wheel farthest from the master cylinder and work to the wheel closest.

Dont forget to repressurize the system every so often to around 15 psi.

After you have bleed all the brakes remove the power bleeder and use the baster to remove fluid to between min. and max. line.

Hope this helps.
