Brake/Clutch fluid reservoir

Recommended Posts

Planning on bleeding the brakes, opened the reservoir and there is a plastic filter(cup), tried to pull it but no cigar. Afraid if too much force will break it. Is there a trick to take it out?

Use two small flat head screwdrivers (for prescription glasses) and pry at 180 degree at the rim of the cup.

Why? It is not necessary to remove the screen in order to bleed the system.

Probably to get a siphon in there and suck the old fluid out.

Completely unnecessary if you are doing a pressure bleed (Motive system).

My bad, was not specific on why my question. Sburke is correct, wanted to siphon the old fluid from the reservoir. But according to JFP is not necessary. Guess with the pressure bleed the old fluid will be forced out by the fresh fluid.

When you pressure bleed, the new fluid moves through the system like a slug, pushing all the old dirty fluid in front of it, so there is no need to drain the reservoir. That is one of the beauties of doing it that way.

Trying to drain the reservoir can also create issues as people sometimes drip brake fluid in the process which can blister paint and create a mess that is often difficult to clean up.

One more drawback of removing the cup I can think of is without the filter, you may inadvertantly drop some debris into the reservoir.

Someone earlier had ask if they could mix the blue and gold ATE brake fluid. I'm sure you can, but it defeats the purpose of knowing when you've purged the old fluid. One time you use the gold fluid, the next you use the blue. By doing this you'll know when you've disposed of the old fluid by watching the fluid color change.

If you don't have a pressure bleeder and you're doing your own brake work, you should have this bleeder:

Almost done building a bleeder with a garden sprayer.

Along with defeating the purpose of the two colors, the blue is no longer available, but when it was it was exactly the same fluid as the gold, but with a blue dye in it.

John, well that's not very good news... so what is your recommendation on flushing the system? I guess you need to watch the fluid and when it gets clear in color you've flushed the old fluid out?

Basically, we have customers that always asked for us not to use the blue out of fear it would discolor the plastic reservoir, and we have obliged them. When the gold, or ATE 200 as it is properly known, get old and dirty, it is enough of a change when the clean fluid shows up at the bleeders. With the gold to blue, even Ray Charles could have caught the change over, but as the federal nannies have moved to prevent the end of civilization as we know it by banning any other color than yellow-amber for brake fluids, you will need to pay a bit more attention when flushing the car.

Based on my personal experience if you don't mind wasting a bit of new fluid, drain out 125mL per bleeder (or 250mL per wheel) is way more than enough to change out the old fluid. You will always have some fluid inside the ABS system you can't drain out anyway (at least not w/o the help of Porsche scanners).

John,

I had to laugh at the "Ray Charles" reply... very funny and thanks.
