I was haulin azz to work today cuz i was running late as usual and i went to slow down so i did not get a photo radar ticket, my bake petal went all the way to the floor. so i pumped my brakws and it stopped. I checked my resivoir and it is full and i could not find any leaks. my brake seem to be working but the pettle will occasionally do the same thing as it did this am. Would it be my master cylinder going out????

 

when was the last time the brake fluid was changed? Brake fluid absorbs water and when heated the water turn into vapor.

You may have an internal leak on the master or a leaking wheel cylinder that you haven't seen. Also the brake hoses may be bloating when pressure is applied.

 

ok thanks i will check all of my lines and look for leaks again
