Over filling brake fluid

[smileymikey]

Advice would be appreciated, I asked the dealer to top up my brake fluid while they serviced my car. I've just checked and they have overfilled it. Will this have any detrimental effect or is it ok. I have noticed that my mpg has dropped from 49.7 to around 46mpg since the service.

Yes it's well known for MPG to suffer when there is too much brake fluid in.

Ouch!

What I was getting at would too much brake fluid hold the pads onto the discs lightly. The only stupid question is the one you dont ask

However thanks for the demonstration of your superior wit and intellect

oookay

The fluid is filled well above the max level to the base of the screw neck filler spout. It was this that caused me to look in the first place as I couldn't see the level between the min and max marks and the res appeared empty. They serviced the car four weeks ago and Ive covered five thousand miles since ( so I'm guessing it was a fair bit higher, and pad wear has dropped the level) I can hear that the pads are brushing against the disks lightly). I made the comment about mpg as I had noticed the drop since the service, basing fuel consumption on forty thousand miles in the previous ten months.
