If you have been lucky enough that the air was trapped immediately below the master cylinder then it is possible that pumping the brakes released the air completely - problem fixed.

The other alternative (if your pedal is still fairly firm) is that the air was trapped in the calliper and that there is a slow leak in the seal there (which could be how the air got in in the first place). In that case the air could have been pushed out through the leaky seal - bad. The problem feels as though it has been fixed but oil is leaking near to your pads and rotors.

It would be worth an eyeball check round the callipers on both the wheels with the new rotors to look for damp patches, just for your own reassurance.

I think that is what happened, air was trapped,


....they checked my master cylinder, lines, everything, and nothing is wrong with anything.


yipppee!


thanks everyone!

and I did!

it was just that the air needed to come out.


thanks sis!

your hired!

Well, Ive tried adding brake fluid last week, and then had the brakes done the day after that. And when the auto mechanic compressed the piston all of the excess brake fluid spilled out of the cylinder.. and it spilled all over the engine compartment and definitely made such a big mess. . And the next thing i knew was I had to replace my cabinairfilter [ADVERTISING LINK REMOVED] cuz it happens to blow warm air already.. Geesh

And they said that brake fluid does not evaporate. So i guess you have to wipe it off to and clean up any spills immediately. Spilled fluid could damage components in the engine compartment.. And explosion may happen. Really hope not..
