I've had my 05' Super Duty for a few years now. I really like the truck, but the brakes have always been sub par. They work, but they just don't compare to any of the newer trucks I've driven. I've flushed all the old fluid out with fresh DOT4 fluid, I've flushed the hydroboost system out with fresh synthetic ATF fluid, I've put new OEM rotors and Wagner HD pads on the front along with new front calipers, and new rubber lines. I haven't done much with the rears except new pads.

Even after all of this, the truck just doesn't stop as well as I'd like. Don't get me wrong, it will come to a pretty quick stop if I really stop on the pedal.......but you really have to stomp on it if you want to stop in a hurry....I can stop just as fast in other trucks I've driven with a pretty light foot.

Is this just how these trucks are? Are the brakes just not as good as the newer trucks? Is there any other ways to improve the brake feel on these trucks?

Thanks!

Newer is always an improvement. Dana 80 disks are roughly 15” 04 and up IIRC. 2013 up sterling 10.5 axles or what ever the newer axles are called, are upgraded with just as larger of brakes as the older dana 80. So if you drove anything SRW 13 and up that’s what you’re noticing. Larger disks, better materials and more pistons makes all difference.

Look into powerstop brake upgrades. People whom upgrade says they are truly an improvement.

I'm pretty sure the rotors on my 2005 F250 are around 13" diameter, not 15" diameter.

Yes. Dana 80 is 15” ish... I brought up the 80 and newer sterlings to make a difference.

Your 250 has small disks. Did you put any thought in the resolution to your debacle?

Just put powerstop rotors and pads on my 01 f-250 today. I'll let you know in a few days how they work. The best thing I noticed so far is the violent shaking when I hit the brakes is gone. Just smooth stopping now.

Yes, I'm curious how they work. I've tried those slotted rotors on other trucks in the past and they didn't help out at all. All of the area where those slots are, is area that isn't touching the brake pad.....so you actually have less contact between the pad and rotor. Sure, they might work on racecars that get the rotors glowing red hot.....but on normal daily drivers, I think it's all just marketing hype. There is a reason no trucks come with slotted rotors from the factory.

Reason? B/c manufacturers are not speedy. Slots dissipate heat and channel debris away from the contact surface thus increasing grip and stopping efficiently. There is a science behind it.

As I mentioned in my first post, these brakes were mentioned. Hence, “did you put any thought in to it”...

They work.

But they're not going to help stop any faster, they're just not. Bigger rotors and pads probably will, because the surface area is getting bigger, not sure how a bigger rotor will fit though. But that's probably just masking a problem. Assuming it's not normal, then either the assist is weak, or pressure is being wasted somewhere in the system. Like stuck caliper pistons or something.

Whatever you do, don't start changing piston sizes. Like different master cylinders, different calipers etc. That's a bad idea.

I put this pad a rotor combo on my 2000 f250 and it stops a lot better and I have not noticed any break fade when they get hot. I got them off amazon. IMG_0570.jpg

I have been replacing rear calipers about every 3 months. what brands/part numbers use a metal piston in the calipers? the phenolics seem to fail.
