Air in brake lines = fender bender

[jlenovi]

Pedal went to floor (35K mainly HWY) resulting in fender-bender. Plenty of pad, grooves in soft rear rotors but not enough to cause this. Old mechanic sez: you have air in lines. NO WAY! Well, he cracks right rear bleeder, waits, finally fluid starts. Closes bleeder, I have pedal. Brakes have never been touched and always felt a bit spongy, this is the way it came out of Louisville. Anyone else experienced this or am I just lucky? :fire:

It's possible... the factory filling method isn't fool-proof. They evacuate the system (which also checks for leaks), then fill it with fluid. They do not bleed at each wheel. It's certainly possible for some amount of air to be trapped. It's rare, but it does happen.

mine are sota like that. but you can put the pedal down then when you let up there is pressure.
