I've always had a little vibration but it has been starting to get worse. Recently I think my e-brake has been acting up to make the whole truck "shudder" like others have talked about. It finally gave out. Going to the dealership armed with good info tomorrow!

From: Georgia on my mind...
For what it's worth, I've been driving around for a couple weeks now on these new calipers. So far, so good. Pedal feel is good, probably better than it was with the original stuff, stops straight and true, no pulsations. I replaced the rotors on my truck before, so I resurfaced them this time with an Accuturn on car brake lathe, removing about .015" on each side of each rotor. And for y'all that really worry about it, brake dust seems to be lessened with these new pads as well.

FRONT BRAKE ROUGHNESS - SHUDDER WHILE BRAKING
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
1. 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.
2. Determine if the vehicle has the old or new level rotors (Figure 1).
a. 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.
b. If new level (47 fin) rotors are present, perform one (1) of the following:
(1) 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.
(2) If rotors are beyond machinable thickness, the front rotors must be replaced.
3. 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.

During that time, he told me most dealership mechanics are in such a hurry to finish they don't take the time to completely & properly bleed brakes. His reccomendation is to bleed as much air out as possible, till you have reasonable pedal, then drive the vehicle around a bit using the brakes, like in a parking lot, then bleed again till you have a good hard pedal. Repeat as necessary...
I have an 04 screw and just had the tsb done on mine. Yes, I had the older narrow rotors. They replaced whole front brake system as described in the tsb. Drove it off the lot, & whoa, soft pedal. Drove right back in & said this is not right. Tech came out & I said I thought there was still some air in the lines, I could push the pedal (hard) nearly to the floor. He drove it around in the lot, stomping on the brakes, took it back into the service area & bled brakes some more. Came out & said they were fine, bleeding was clear fluid. But, when I got back in, the pedal was much better. Not as hard as before the tsb service but much better than before. So truth is he DID have air in the lines. Try bleeding the soft pedal and be prepared for it to take a while and use up a lot of fluid.
For what its worth, the steering wheel no longer shakes when I brake hard at speed, so I think the tsb worked for me.
