Car : S3 205 GTI
Any idea what the plug is for? It runs along the back of the engine bay up the top from right to left (when viewing engine bay from front).
How does the brake system work on the 205? Since i have rebuilt the engine something is just not right with the brakes, it feels like i am not getting any assistance from the servo, the brakes are absolutely terrible.
Do the brakes rely on any power to boost the system? or is that not how the servo works? (is it purely hydraulic or rely on some kind of electric pump?)
Not sure if the plug i am asking about is related, it happens to end just at the brake master cylinder/servo
Maybe i just need to bleed the brakes...the pedal doesnt feel too mushy though!
