i'm not arguing, or stirring up a bees nest, i'd like to find out the truth myself, now that i'm hearing all this other stuff.

what about Nascar @ martinsville... they burn up bearings, warp rotors and everything else... i know its not as intense on the road... i just remember the video of the rotors on the race cars gettin red hot to the point where they bake the grease in the hubs and melt the tires off the rims.

 

All that is a byproduct of extreme braking and the intense heat that results from it. Watch one of those under car cameras. As soon as the brakes are applied, the rotor gets cherry red. That heat transfers down into the hub and on into the bearings, cooking the grease and burning up the bearings.

I'm not saying you can't warp a rotor from overtorquing the lug nuts at all, but it's from the torque applied to the rotor bending it and not heat from binding a bearing.

 

the owners manual on my 05 says 150 ft pounds...

every vehicle I have ever owned has been 100, this sounded kind of high, but what the hell

 

Thanks, yeah my manual says 150 also, but it is always possible to miss a service notice or some change so I was wondering.

I have seen disk rotors warped by over tightening. At various brake schools they listed over tightening as the major cause of warping, and brake heat as a weak second.

With anti-lock brakes I would be surprised if any normal brake use would generate more heat than the bearings could handle, everything else being equal.

I am suspicious that Ford may have had a bad run of rotors. It does happen. My brakes have been good, but just this week started to act like they were warped. The truck has never been abused, and no harsh braking in the last three months or so.
Mostly around town, with mixed freeway, and all easy stops. I will take it in to the dealer and have them take a look soon. If they won't replace the rotors, and since it is so slight I suspect they won't, I will pick up some aftermarket rotors and pads and just upgrade.
Rather not at such low miles, but the couple three hundred bucks is cheap enough that I would rather do that than fret about it.

oops

 

Doesn't the front brake tsb cover all this? I heard from my ford mechanic friend that there were a bunch of bad brakes on the 04-05 models.

 

The recommended for these trucks is 150ft lbs. The main reason for warped rotors is uneven torque. Uneven torque will kill a rotor every time. Since I started torquimg my lug nuts by hand, I have not had a warped rotor.

 

True. My rotors warped inside of 4000 miles, and Ford replaced the front calipers, and rotors with the improved versions under warranty. There is a TSB posted somewhere on this forum......Search.

 

hmm never seen them burn up bearings and have never seen a tire melt off of the wheel, but then again i dont watch nascar that offten o yeah thats because i am at a different track racing my speed truck and glowing my rotors, my sister races the same trucks i do she uses her brakes more then me her rotors get red and so hot it melts the glue in the brake pads onto the rotors and we have never had a problem with wheel barings, we just re pack them every other race

 

You can do a search for my user name I am on my 4th pair of rotors with 2 turns on different pair, and they are warped again. This is my 3 F150 and the frist 2 didn't have problems. I also have a Lincoln Avaiator which is fine.

I looked at the lemon law because my truck has been in the shop for 18-20 times, but was told to trade the truck because the cost would be more then loosing my shirt on the trade. I have kept the truck and today when I hit the brakes I get the vib, still have the clunk and the AC sucks monkey. I still have the truck and probably will keep it a while till it makes sense to trade it.

The problem I have is Chevy's are ugly, Dodge has even worse quality issues then Ford, and I will not drive a Toyota or Nissan. So there you have it, F150 till it rots! But I still even after all of the crap I have been through love this damn truck! Good luck with what ever you decide to do, I would just trade it at this point.

 

Unreal. Im glad my dealer has been an absolute pleasure to work with. I had the rotor fix done at about 18000mi no ?'s asked,well after brake "warranty" is up. I cant believe your two dealers wont help you out. Its a known issue for cryin out loud! I would definately complain to Ford. Go for blood and take em for every dollar you can! Hope it works out for you...

Later,

I have a 2004 Lariat crew cab and I complained about front grooved rotors and brakes squealing at 5,000 miles and I think they just cleaned them with brake cleaner. I took it in again at 14,000 and complained again about grooved rotors and squealing and they turned the rotors!! The told me the rotors are under warranty but the brakes are not.
I'm planning on replacing the pads with the Hawk HPS that I saw from another member. It sucks you spend big money for a nice truck and have to deal with squealing brakes!

 

I think brakes are considered wear items and are only warrantied for 12,000 miles.

 

Hey guys, look at the date of the original poster and the number of posts.....it's obvious this guy's not comming around again.

05-21-19 FRONT BRAKE ROUGHNESS - SHUDDER WHILE BRAKING

Publication Date: October 17, 2005

FORD: 2004-2005 F-150


This article supersedes TSB 05-06-21 to add new parts and update Service Procedure.

ISSUE:
Some 2004/2005 F-150 vehicles built before 11/29/2004 may exhibit front brake roughness and or shudder while braking.

ACTION:
Service the rack and pinion, rotors, and caliper assemblies as needed, based on vehicle build date and current part levels installed on the vehicle. Refer to the following Service Procedure.

SERVICE PROCEDURE

Vehicles built prior to 8/20/2003 require the replacement of the rack and pinion assembly if it has not been replaced. Refer to Workshop Manual, Section 206-03 and 211-02.
Determine if the vehicle has the old or new level rotors (Figure 1).


Figure 1 - Article 05-21-19


If old level rotors, replace the front rotors and front caliper assemblies. Refer to Workshop Manual, Section 206-00 for front rotor and caliper replacement.
NOTE: WHEN REPLACING THE ROTORS ON 4X2 UNITS, A NEW SPINDLE NUT IS REQUIRED.



If new level (47 fin) rotors are present, perform one (1) of the following:
If rotors are within minimum thickness specifications, machine the rotors using the Rotunda on vehicle brake lathe and the Rotunda adapter kit 201-R0093. Refer to the Workshop Manual, Section 206-00 for the correct on-vehicle brake lathe procedure.
If rotors are beyond machinable thickness, the front rotors must be replaced.
Install new service fix calipers.
NOTE: REPLACE CALIPERS WITH NEW SERVICE FIX CALIPER ASSEMBLIES BY REMOVING THE CALIPERS AT THE KNUCKLES. THE SERVICE REPLACEMENT CALIPERS WILL BE PRE-ASSEMBLED WITH ANCHOR, SPRINGS, AND PADS. THE CALIPERS SHOULD BE INSTALLED AS A UNIT WITHOUT DISASSEMBLY.
