This is an absolute mystery to me and I would appreciate it if someone with an understanding of brake systems could give me a few tips.
I had the front brake pads replaced on my A4 B8 2010 sedan and ever since the replacement the brake pedal felt a lot softer. I can press the brake pedal until it hits the floor. Initially, I thought this is due to the pads adjusting to the brake disc, since I kept the old discs because they are perfectly intact.
However, after over 1200, miles the brake pedal behavior is the same. With the engine running, I'm able to press the brake pedal to the floor. However, when the engine is off, this is not possible. Also, if the engine is on or off but the electronic handbrake is on, the pedal cannot be pressed to the floor but there is some strong resistance just before the pedal would hit the floor.
I've been in touch with the shop that did the replacement and they said the brake fluid is old and must be replaced. Fluid replaced, but the problem remains. The shop says everything looks ok.
What could the cause for this behavior be? What mistakes could the shop have made that causes these symptoms?
