It's because the truck couldn't get up to speed loaded up:D

One poster on BlueOval made the comment that the 5.7 was tied to mandatory upgrade options and trim pkg's, this is of course untrue. Now Ford does sell stripped full crew cabs in F-250 level and up with vinyl floor/seats no power windows, ect, but very very few, and I don't think the F-150 comes as a full stripper in crew cab configuration. Either way the XLT and above trim levels are what most buy.

While you guys are laughing, Ford uses an apportioning valve in the brake system. The valve senses load to the rear rotors. When the truck is empty, there is very little braking action with the rear brakes. When loaded the valve will send more brake pressure to the rear rotors resulting in shorter stops when loaded. So yes the Ford will stop shorter when loaded due to more equalized braking from the rear brakes. Make fun of Ford all you want and they definitely give you lots to work with but the brakes are good. That is, as long as you like your front wheels brown from brake dust- ever notice? Ever ride in one that the rotors weren't warped?

Every Ford truck I owned braked ok, but like you mentioned the rotors were quickly warped and had a couple of calipers completely seize up while driving!

Ford boys are the LAST people to talk about brakes!! All the brakes on my last 5 Fords have been complete [email protected] and don't stop worth $h1t.

Is there any truck/SUV that doesn't have a load sensing proportioning valve anymore? Well, the Tundra has Electronic Brake Force Distribution (EBFD), which is better than a simple/dumb proportioning valve. Either system should attempt to optimize brake force depending on the load, if it makes a loaded rig stop faster than an unloaded rig it is either malfunctioning, or very poorly designed. It should not sacrifice unloaded stopping for loaded stopping.
