Quick question.

Is it normal to have brake fluid in this lip?

It isn't normal but if it was over filled and you ran it hard you may very well have a bit of an overflow. Or it could just be there from last time it was opened/filled.

Clean it and keep an eye on it and see if it does it again, and check for leaks.

[BIGJake111]

Yeah I am particularly puzzled as I had not ran the car hard but I had just spent 10 minutes at slow speed in a parking lot with lots of light braking. I'll keep an eye on it

It's not unusual for a track car to have some fluid there. The cap has a vent in it that allows some fluid out under high G's.

Looking at reservoir dead on from front, there are max and min indents for fill level.

Aside from being over-filled, all things considered, your fluid definitely needs changed/flushed. It should be 'golden amber' (a la olive oil coloration - not motor oil).

Instead of flushing all that old sludge thru the lines/system, I'd instead evacuate from top of reservoir...

Good luck

Were you slow driving to bed new pads? Reservoir looks overfilled to me.

If you ever spill even a little bit of brake fluid down there when bleeding or flushing your brakes, it is very hard to get out, it just seems to swirl around that lip and go under the edge of that cowling. I finally said enough and took off the cowling and got a toothpick and some of those blue paper shop towels and got it all cleaned up.

In the photo, your brake fluid looks overfilled (maybe you are on a slope). If overfilled I think it can come out the vent as others have said. I fill mine right to the bottom of the little triangle bump out above max.

I've never been able to take out the little screen before, but then someone told me to give it a little turn (I forgot which way) to remove. Does anybody know?

[BIGJake111]

It was on a major slope when I took the photo, hilly parking lot.

[BIGJake111]

So is this a vent for heat or rather g forces?

G forces is something my car has been through a good bit of lately, whilst heavy braking not so much.

[BIGJake111]

Come to think of it I had just been up a 25% grade in the parking lot and had to spend more time like that then usual due to traffic, maybe gravity just worked some out of the cap?

Never have to turn mine - just pulls right up (did in my 986 and does in my 997 and 95B). Has a lip/ridge or two which are compression fit to hold in place keeping it from slipping down in though. Hmmm...

Two things:

- still looks overfilled - regardless of slope based on minimal air pocket visible...

and more importantly

- fluid is filthy and needs flushed ASAP

Good luck

Take a pic on level ground.

You don't check any fluids on a slope.

[BIGJake111]

Still overfilled not on a slope. Just not by as much.

I don't seem to remember seeing the fluid above the max, what would cause the level to rise without adding fluid? It hasn't happened overnight but the fluid in the past has been beneath the Max for sure.

Is your cap tight?
When was the last time this was messed with?

[BIGJake111]

I think last oil change at the dealer. I'm changing the oil and fixing one of my front fans in the coming weekends, I think I'll add brake fluid to the list.

flushing and bleeding the brakes is a easy DIY

[nicecar]

I noticed mine doing the same thing so I added plumbers tape to the threads and that worked for a while until recently. I just last week took the tape of and cleaned it off then carefully rotated the cap counter clockwise until it made a click then tightened being careful not to over tighten. Same procedure used for coolant cap. Someone on this forum recommended this procedure when tightening the bolts for the bleeder valve on the coolant tank which are seated in plastic which you dont want to cross-thread. Great top tip....thanks to this forum..What is a top tip anyway? The tall guy on Wheeler dealer says it.

[BIGJake111]

Just want to update. Checked the level this morning and it was right at the max. Seems to be temperature related.

[BIGJake111]

New brake fluid, oil change, and a nice wash, car feels great.
