Brake Pedal continues to go to the floor

Recommended Posts

Hello my name is Cameron and I'm working on a 2013 edge right now and have done the brakes but the pedal is still going to the floor. I've replaced the master cylinder, abs module, put new rotors in the rear resurfaced the front and put new pads all the way around. I have bled the brakes I would say a tot of ten times and the pedal hasn't changed. It'll feel like it's going to build pressure but still does not. Can anyone help?

Few years ago I had the same problem.  Took it to the dealer and they replaced the brake booster.

I've been all the way through this... brake booster recall (small tear in the diaphragm) HPU replacement (advised by main dealer) Master Cylinder replacement (done same time as the HPU - on dealer list)... braking system felt better for a refresh (car was IRO 240k km) but none of them fixed the intermittent issue... after a test drive I requested the dealer to replace the vacuum hose (at my instruction and cost) as it was the only item pending that hadn't been changed... and they point blank refused. 

 

Fixed the issue myself with a $30 OEM replacement hose and took it in to the garage and dropped in on the service advisor's desk and left after a brief discussion.  My car was revving up intermittently also, which is indicative of a vacuum leak / air ingress. 

 

Hope that helps.  Keep us posted.

Basically there's four things that can cause the brake pedal to go to the floor.

1. Air in the Brake Lines
2. Brake Fluid Leaking 
3. Brake Booster Is Failing or Is Bad, and 
Master Cylinder Is Going Bad

 

As you have addressed all of these (I assume you would have noticed a leak), I'd center in on bleeding the abs module.
