Brake booster, Vacuum leak?


Recommended Posts

Hi Guys

 

I have a 2011 edge sport.

 

I kind of feel the brake had some issues because it felt spongy and very soft so I recently took my car to the dealership and had a brake booster replaced under warranty.

 

Right now the brake feels normal. However, the new booster still won't hold vacuum for very long. It seems to lose vacuum slowly overtime.

 

If i drive it to work and park it for 8 hours, the pedal is still soft after work. But If i park it in my garage for like a day, the brake is hard when i try to start up the car.

 

I also have a Honda accord, I can park it in my garage for 1 week and the brake pedal is still soft when i step on it.

 

I'm just wondering are you guys all experiencing the same or this is just me?

 

Under normal circumstances, how long should the brake booster hold its vacuum?

I had my booster replaced under (extended) warranty this week. Pedal was spongy and I had to pump the pedal before. Now it's firmer and I don't see it loosing vacuum after setting.

 

You may still have a leak in a connection or hose somewhere.

 

Honda is known for a"soft" pedal. Of the Honda's I've owned I always hated the brakes.

Hi Enigma-2

 

Have you tried to park your edge for at least 2 days and then try the pedal out? If park it overnight i still have a soft pedal in the morning. But if I leave it for more than a day then the vacuum is completely gone - a rock hard pedal.

 

However, my pedal during driving feels great, very firm and responsive.

 

It bugs me a lot as my accord was parked in the garage all week long and i went to start the car, the vacuum is still there.

 

I don't know if it is a ford thing or i have a leaking hose on my edge sport.

I have tried to get it to a dealer here in Odessa during the 2nd week of June and they gave me the run around about how they can't set an appointment even three weeks out (which I think is total bs) This is three different dealerships. I called a dealer in College Station, TX and they said that they would look at it on the 27th of July after I move down there for work and would have it diagnosed in one day, and if it will take longer I will have a rental covered under my premium care warranty that same day. At least it sounds like I am moving to an area with a great dealership. Also thank you for the replies. The service department in College Station said he thought it was the brake booster after giving the symptoms I was having. He also said that it was BS that the three local dealerships here wouldn't take an appointment and would take 5-7 days just to look at it.
