Hello. I've been up and down different info resources online and even to a mech or two. So, here's what I need to know:
Let's say the mech has checked everything in the brake system and had found nothing wrong. BUT, the brakes are spongy and the pedal needs to be depressed all the way for a complete stop. Worse during slow driving and stopping than anything else.
How else apart from actually driving the car can the Mech come to the conclusion that the brake line has to be bled? (eg, there's air in there?).
I'd truly appreciate any input regarding this. Thanks in advance.
