All o f sudden my 00 ws6 6speed manual the brake pedal got real hard and it didnt wanted to stop.i almost hit the car in front of me. All my way home a had to push real hard on the brake pedal and sometimes pull the emergency brake to stop it...
What could of went wrong .... and what can i do to test everything before i star buying things that i dont need..
Rotors are good .pads are good. Just recently put some 17 torque thrust wheels on it....i drive it one time a week...wat went wrong????

 

check your vacuum hose from the intake to the brake booster .you mite need a new brake booster .

 

agreed. brake booster

 

How can i check the hose from the brake booster... a lot of tips on the net say to blow on it and if goes easy is good if not its bad.....is that true ????

 

Did you check your brake fluid?

Fluid, master, distribution box, lines, pads, rotors, CHECK THEM ALL. Obviously something is impacting the brakes performance. I never check one or two things with brakes, I always check all of them above. You can never been too safe with your brakes.
