My truck 2004 F150 FX4.

My issue- crazy shaking rear end while i was driving on highway for like 1 mile or so then it went away, not even press on brake pedal- nothing. its like out of blue!

i pulled over and checked, i could/see smell smoking from rear end brake.

I searched in here and found out its common know that rear end drum got stick or stuck caused rear end shake.

so I had a auto shop guy checked everything and said it looks good and nothing rust etc that he find to be normal. he re-adjust rear end drum E brake and lubes etc..then 5 days later...It came back again- on highway!

Today, I stopped by auto repair shop- same guy he got clueless too..told me to drop it off tomorrow to check everything..

He suggested me to get new rotors, drums since its orignial rotors all (4) and is approx 66,000 milages on it.

Advice will be GREAT!!

Thanks!

Sounds like you have an emergency brake sticking as othersand I have had. If you do not use it often it tends to stick more when you do use it. Make sure it releases when you pull the release. you may need to replace the shoes (emergency brake) and/or the disc. Make sure all of the cables work freely.

 

Is the wheel hot when you pull over to check it. does it pull to that side?
If not you may have a axle bearing on it's way out. check the diff fluid and vent. jack it up and lift on the axle to check for play.

 

oh yeah its HOT when i touch the rotor near the rims. nit doesnt pull to side.

I removed rear end and checked everything. no play in there from axle shaft.

I redjust drum brakes, clean it up etc and its back to normal...i touch rear rotor and its MUUUCCHHH better, kind of warm to touch..

thanks!

I had that happen under warranty and they replaced the rear pass caliper.

 

how do you figure it out ?? or a dealer figure it out ??

Thanks!

 

I've read on here that there is a TSB out on sticking e-breaks. If I remember correctly it involves replaceing one of the cables and I think it was the passenger side.

 

Yes, I just had it done on 08. They replace the parking brake cable and bracket assembly. I'm almost 100% certain that you have the same thing. By the way, it took several times to fix it correctly, just in case you needed more encouragement. I wouldn't let them hose you on it, as said there is some type of problem they are aware of.

 

I had an issue when the truck was 4 years old, there is a pivot point as part of the manual handbake, this is inside the rotor and a link was siezed where it attached to the brake shoe, the other thing this can do is prevent the handbrake from holding the truck when applied.
I have won the award for rear brake life, on 159000 and still on original rotors, new ones to be fitted next week .(3 sets of pads in that time)
