I was bleeding my brakes today, replacing all the brake fluid (old) but the helper I had released the brake pedal too early, and it sucked air into the system. Then the pedal fell to the flood so I re-bled the lines and no more air bubbles. The pedal returned to it's normal height and a nice solid feel, as good as the tC gets.


My question is. Do I have to bleed the master cylinder as well if the air entered into only one brake line? The reservoir was full the entire time this happened.

 

If I'm reading you correctly you should be fine. The air bubbles wouldn't have gone all the way up the lines, especially if you re-bled them right away.

 

^^ makes sense, yeah I bled the one line within about 2 minutes and then (about 20 minutes total for all lines) went around to the rest of the lines to make sure all the air was out.

cool, just checking, thanks for the info

 

Anytime. Just pay attention to it and should be fine. I remember when I first bled my brakes, I spent the next week wondering, "is that how it's supposed to feel?"

Happy motoring!
