Hi,

So this morning I bleed the brakes using mityvac. After the first short drive ~15 mi, I checked and found that the fluid dropped 1 cm. I topped up and took another short drive. Dropped another 4 mm.

After the third drive, it stopped
dropping. I checked before topping up there is no leak.

Why did this happen?

One way seals? Reservoir?

 

There is a certain way to bleed this car and if I remember correctly, it has to do with the electric pump.

The fluid level, increases and decreases as you drive then park the car.

If the fluid level does not continue to leak then you should be okay.

BTW, do the brakes feel good?

 

Feels just like before. The fluid that came out also looked like new.

Maybe it was time wasted.

 

Never hurts to reset the clock and now you know the status of the fluid change interval.

 

Strange thing happened:

Last night art the end it dropped another 1 mm.

This morning I went to check for leaks, the level is way above max (reservoir full) Where does fluid usually go in this car?

 

I guess when it pressures up the system, the level drops.
When you first turn on the key, listen for the pump while you jump out of the car and watch the level go down in the master cylinder. The pump is very loud and will run for a few seconds.

 

I believe that the owner's manual states that you need to pump the brakes a certain minimum number of times before checking fluid level.

 

OK, didn't know that sound is from this pump before. Also didn't know the fluid checking procedure.

thanks
