Brakes become soft

[Mohammad-997]

i have a audi a3 8p 2.0tdi and recently the brakes have become soft sometimes. I would be driving and when i brake sometimes id have to press the pedal all the way down for it to actually grip the brakes. Most times it just grips it as soon as i press it.

check brake fluid

Possibly a vacuum leak - could be park of your shaking car issue too?

Can you get a diagnostic check (VCDS, Carista, OBD11) done to see what codes come up?

If you also have a shaking car issue are the wheel bearings good? If there is play then you can get pad knock-off which lengthens the brake pedal.
