Fading break pedal

[kramerpage]

While backing out of the driveway this morning the brake pedal went completely to the floor. It kind of scared me because I wasn't ready for it and I haven't had coffee yet.

I recently had new brake lines installed from the output of the ABS to all four wheels and also installed for new rubber hoses. When I receive the vehicle from the mechanic the pedal had top end play but it didn't fade if that makes sense.

So I went to Harbor Freight and got a bleeder that you hook up to the air compressor and did all four wheel cylinders I got small fine bubbles out of the right rear the left rear was fine the right front find the left front it was weird I got a lot of bubbles and the bubbles never stopped.

I have no idea where do you even start as far as troubleshooting. The vehicle stops fine it's stops straight it doesn't pull it's just about 2in of pedal before it even begins to break so if you have any suggestions I would appreciate it thanks.

Have it towed back to the mechanic and have him fix the vehicle correctly.

I drove it over 1000 miles with out issue. I don't believe I could pin it on his work or not. Hence I bleed the brakes thinking maybe he missed something.

I drove the vehicle today and it stops fine. when I went to park and applied brake and placed in park the pedal went to the floor. Any Ideas? Brake fluid level has not moved. Could it be air in abs unit from installing new lines? Can I disconnect master cylinder lines and place a threaded plug in both outputs from the master cylinder to determine if its the MC?

Any vehicle with an ABS braking system must have the ABS unit bled when replacing brake fluid and/or brake lines.

Ford’s hand held computer tool enables the technician to operate the shutter valves in the ABS module to remove and air in the module. On GM vehicles, the technician uses a GM Tech II, hand held device to operate the valves.

I believe the brake system was not properly bled the first or second time. There may be another defect in the system also.

You are endangering yourself, your passengers and other motorists by driving the vehicle KNOWING there is a serious brake problem

I still believe having it towed to a qualified brake mechanic to be repaired is the most prudent course of action.

PS - When traveling to or through Columbus, my wife and I always stop and eat at Schmidt’s Sausage Haus in the German Village.

Thanks for the insight...Love to be SCOLDED like a child. Geee Thanks

I have an appointment august 5th . I would like to attempt the repair myself if its the MC but I dont throw parts at vehicles so I posted here.

Schmidts went down hill after the owner died and his lazy son took over over 12 years ago. Place is horrible and filthy. Just sayin...

It’s been quite some time since we visited Columbus and ate at Schmidt’s. We must have got lucky - as I don’t remember a bad experience. Thanks for the heads-up.

Good luck with your vehicle. I own a 2015 Expedition Limited 4x4.

Could possibly be vacuum lines are leaking & worn out. Will also affect braking

 

[kramerpage]

Thanks. I checked vacuum, booster and MC seal when I removed master cylinder. Pedal hard when vacuum hose disconnected.

Ok. Mine, 2004, had a problem also & ended up being the hose assembly coming off the Vacuum tank. Yours may be different. Had a light leak when braking (hose deteriorating) & brakes were a little spongy. New hose & great breaking
This is yours:

Dude, another member says Rock Auto's website is terrible, so I'd be afraid to buy from them dude.

Up to you where You get your parts. I used that link for the Motorcraft part number that fixed my brake problem. I've used the site for 15+ years w/o problems but is your choice. I had to remove the battery & tray for my repair, yours may be different.

In quite a few situations throwing parts on things that work can save you a headache later.

A hose assembly is something you can remove and check for leaks. You can also check that vacuum check valve is working correctly.

I never had a problem with Rock Auto either. They trade customer service for rock bottom price. Crappy service, low price. Usually works for me. I've saved hundreds.

LOL - that's the most optimistic comment I've ever come across for rationalizing the use of a parts canon.

If you plan on keeping a vehicle I stand by it. Not enough life time to analyze things to deaf. Got kids and jobs to deal with.
That why people come here so others and analyze for them and save some IRL time. Love the site!

Parts Cannon? I got one of those!

They're expensive to load - that's the only problem.

I'm not saying I disagree with you - I totally get it - but it can be really expensive doing it that way and no less frustrating.
