hi this is my first post on here so hi to every one first and any help would be great..
ive just got a 2003 a4 quattro 1.9 tdi 130 and i must of covered 80 miles coming home with no probs at all till the nexted day, at slow speed my brakes went rock hard like the servo was not working and now its done it to me about 4 time but only at say about 5mph and my steering is the same some times again only at low speed or when im parking it goes stiff..
i have checked all the fluids and they are full and i cannot see any leeks.

so can anyone help thanks
