I am having issues with my brakes and wondered if anyone could give me a hand diagnosing it. My brakes work fine sometimes and other times the pedal goes all the way to the floor before I get brakes. When it does this it locks up the brakes and my brake lite comes on. Anyone have any ideas on what this might be?

 

low fluid, or a vacuum leak.

 

put constant pressure on the brake pedal dos it remain in the same place or is it slowly going down if it creeping down the master cyl is by passing pressue inside it self replace it

 

X2 - bleeding your brakes might help too.

 

When it works it seems to hold steady. What is the best way to check for a vacuum leak?

 

anyone?
