Good day!

So i am building a brake pressure bleeder out of a garden spray bottle. I just bought a used brake cap and took it apart.

The car that i am trying to bleed is a 2005 Honda civic. The following image below is the break down of the cap (bought one from a junker)



What is the rubber part on the right for? Also what is the purpose of the white part?

Also in the reservoir there is a screen assy. is it removable?

Thanks

i believe that white part holds the black rubber, which "seals" the cap from the brake fluid spilling if somehow ur brake fluid boils n spills out.

The rubber probably locks out moisture. The screen does come out, get a grip on it and it pulls right out.

yeah you really dont want dirt and water vapor in the brake fluid so the cap is very well sealed.

Thanks guys for the help

So i've modified the cap into what i want to be. I had to take the white part out and use a 3/4" scotch-brite pad and grind down the center raised portions.

I am going to take some RTV and seal the white part onto the cap (fillet seal). I then put the rubber on, and punched a hole through the center to allow for a fitting to pass through. I am going to seal the rubber to the white part, as well as seal the area around the fitting where the rubber meets.

If this works out, i'll take photos.
