Brakes Wheels 1st Gen Tires Most liked posts in thread: Boiling fluid out of the resevoir

My guess it is the latter (overfill) -- I would think you would have boiled over last summer when you were trying to melt down your calipers. Is all the same except for the added ducts?

 

Regardless of what I've done to my brakes on the track, the only time I've had the fluid come out of the reservoir was when i filled it past the "max" mark, back in 2003 when i bought the car. I thought something was wrong with the car until I realized it was just user error. Overfilling slightly was a habit left over from racing old Alfas.

 

gonna have to go in the overfill camp on this. The only times I have experienced the same situation, was when I thought I was doing the right thing and topping off all systems...when in fact, closed systems need room to grow, and if they are filled to the max, they only have one place to go, out.

 

I've also experienced brake fluid sloshing out of the cap during track use. Filling only slightly above the "min" mark and not all the way to "max" has completely solved the issue for me.

Been there, done that, have the stains from overfilling to prove it.

 

Add a brake reservoir sock to at least catch some of the leakage from dripping down and attacking your paint.

 

That's funny to me because years ago on one of my Alfa racecars, I used... a cut-up sock. Never occurred to me to make it a real product!

 

Sounds like overfill. Sometimes when you swap from worn street pads to fresh track pads you can push the fluid back up into the reservoir. That'll push it over the max mark. The other option is a master cylinder leak, but you'd feel that in the pedal.

 

I cut the toe ends of old socks and wear them when working on vehicles. Saves the forearms.

As for the thread sounds like to much fluid. The BMW/MINI brake system fluid tank has a brake fluid level switch incorporated in it. So if you are low you will know it.
I often see the fluid tanks over filled on MINIS especially after someone changes out the fluids and bleeds the system. Read the Bentley procedure and watch the levels. Remember that temperature and humidity can effect the total volume during the procedure? Less is better.

A nice tool to have in the box for the track guys and very inexpensive.

Less is better should be taken with a grain of salt, always fill to the indicated level.
I would rather have a mess than be in deep trouble or dead because of a brake failure.

 

DID I EVEN SAY FILL LESS THAN THE MINIMUM ??? GO READ MY POST AGAIN!


And you should really apply at some auto shops to work on peoples cars with all you tremendous wisdom and experience....:crazy:

Was I not clear on reading the Bentley manual and perhaps a call to the local BMW/MINI dealership service department for information on proper procedures? Haven forbid that I know what I am talking about after 30 plus years in the business...:lol:

Grain of salt...? You should be the one that should never work on your own vehicles everyone's life and mine may depend on your lack of mechanical knowledge!

Did I take you comment personal....yup!

Brakes should never be taken for granted or worked on by the in inexperienced!!!

Get one of these like I have and come post here!

Geeeez where do these people come from?

 

Why would I want to apply to work at an autoshop, I work at Victoria's Secret.

 

Yep, was just a full moon...

The consensus said to fill a little over the MIN mark to be covered on track. Not sure what we are now arguing about.

Personal attacks will not be tolerated at all.

Do I need to bring this out of the closet?

 

wow, are you are douche by profession? OR, are you overly sarcastic by profession? I don't have a gauge to distinguish.

 

This has to stop. (kinda funny when you realize the thread is about brakes)

These personal attacks will not be tolerated at all. Disagree all you want, but there is no reason at all to call each names or insinuate any lack of skill by others.

As I said, from posts others have made when topping off brake fluid in track day preparation it is a good idea NOT to fill to the MAX mark but to be above the MIN mark. In addition a sock of some type around the reservoir will help to sop up any leakage.

On that note, this thread is was closed.
