Well I was driving home from work Friday and I got this horrible shake, the whole truck was shaking bad. It was so bad that I had to pull over and stop once I pulled back on the road it was totally gone for the rest of the ride home. On Sat. I went out for awhile driving on the highway and sure as sh^& it came back, I went to my dealer and they said that it is some parts in the rear end and they put an emergency order on them because the parts are back orderd. I know there are others that had this problem can you please let me know what the fix was? This has me very pissed and I only have 3000 miles left on my warrenty. Thanks guys for your input!

 

There have been alot of folks who have had their parking brake stick partially engaged which causes a severe vibration like you describe. Have you checked your rear wheels after this has happened?

 

No I did not, but it is funny you said that because I smelled brakes burning right after this has happened but thought nothing of it because I was on the high way and there were alot of other truck coming down the hill! I wil check this tonight if there is any other info please post!

 

Do not let the dealer start disassembling your truck! Next time it happens pull over and check the rear rotors. If one of them is smoking hot, it is the parking brake. I swear that Ford is getting bad reviews and wasting millions of dollars over a 50¢ part.

Parking Brake Fix

 

Wow I think that is it I can't wait to get into it tonight, thanks guys for your help if there is anything else let me know!

 

You will need a drum brake adjuster to loosen the shoes enough to get the rotor off:



A spring pick will come in handy, but why not just get the set:



One man bleeders are great:



You won't have to do any bleeding, but as long as you're there, and the truck has 33,000, its an easy time to change the fluid. It may also firm up the brakes.

Us older guys have worked on lots of drum brakes before. They need to be adjusted manually. Get an old repair manual for drum brakes, they're all the same.

drum brakes on a '04 f-150 ? I hope not, I haven't seen any...

It's definately your e brake. I just make sure I release three or four times before rollingto make sure it has disengaged before driving away IF and when
I use it. I really don't use it too much unless I'm parking on an incline ....

 

the e brake is a drum style system. There are pics here if you look...

 

 

I had the same problem, on mine it was the E-brake cable on the drivers side that was binding and not releasing the brake.

 

I'm lost... I thought all F150's had disk brakes all around. I know mine does

 

They do have disk brakes, but the e-brake is a drum brake inside the rear disk brake caliper...

You can see in the pics that there's "ears" that stick up to the right to hold the disk brake caliper.

 

Have same vibration problem. Dealer replaced front rotors and driveshaft. Rotors were warped anyway. But did not replace pads after I told them to. Did not fix vibration. I was po'd. Fortunately I know the VP of the dealership. Boy did he get an earful. They took the truck back in and promised it would be right before they released it.

This is interesting and you might want to check yours. The holes in the rotors were too big for the lugs and were chewed up around the edges from slamming on the lugs from shifting back and forth. Talked to a friend of mine that is a front end specialist. He said some F150s have 16mm lugs and some have 14mm lugs. He found this out from work he has done. And it seems it is hit and miss on what rotors are delivered. Take off one of your front wheels and just look for oversized holes for your lugs. If you turn the rotor back and forth it will go clank, clank. Imagine that movement with all the force of braking and acceleration. Just because it is sandwiched between the hub and the wheel doesn't mean the rotor won't shift back and forth. This might explain the clunking sound some owners complain of when coming from a stop.
