It is around 90 today in Seattle, and I was on the last leg from Downtown to my house. (hour plus drive with traffic). I did stop for about 30 min to run a quick errand, but then I jump back in the Ex and headed down the local hill, when all of the sudden my brakes no longer felt "grippy." The peddle was solid, but the brakes felt soft/slippery. I nursed it the last mile home, without incident. I did notice a metallicy smell, but could not figure what wheel it could be coming from. All four brakes were hot enough that a quick splash from the hose immediately boiled off...
All fluids are full.
These are brand new discs, calipers and pads, all less that a month old and greased with the manufacture (Power Stop) provided grease.
I know for me, even after proper bedding of new brakes, within a few weeks, if the brakes get used in a high stress braking incident or just used constantly, I can smell them like they are being bedded again.
Also, when was the last time you inspected your brake lines? Maybe the rubber on such a hot day (baking from the asphalt), and from heavy usage (heating the fluid) made the lines softer than normal.

Interesting thought on the bedding again, that could be the case. I have put an a number of miles since the change, however, I don't have the exact number at the moment.
As for the lines, all mine are now stainless, so that should not be the problem.

sounds like you need to disassemble them and find the cause.
I am going to have to find some time to play around the search things over. Once the brakes cooled at a stoplight, they were working as normal once again...
I will be testing things out early tomorrow, and if I still have issues, Bently_Coop has an IR gun I can barrow.

Right? But it's so easy to forget the KISS principle.
I had a brake problem I posted about one time many, many years ago, describing in the best detail I could what had happened. I even PM'd a few guys whom I respect on this forum, but I could have saved myself any question to what was wrong by just pulling the wheels and properly inspecting the brakes.
I forget the keep it simple when it comes to my own vehicles....and apparently Dave's too.

yup, me thinks a close inspection will quickly reveal the culprit.
that or he used "ceramic" pads ( if they even make them for a super duty )
The pads are the Power Stop Z36 Extreme Truck and Towing Brake Pads
.
just my opinion but ceramic pads have no business on a heavy truck. they are fine for soccer moms mini van so she her wheels don't get dirty. but they do not have the stopping power I want for my truck..
those Z36 are "ceramic" according to power stops marketing but since we really don't know the formulation of their pads, they likely use the "ceramic" as a marketing buzz word.
I doubt that is the root of the problem just pointing out what I see.
Pirate- what is your opinion on the Hawk LTS pads? Seem to be working for my truck which is close to 7k lbs, most I towed was 7k up a fairly large hill and down the other side with my brake controller acting up and I didn't have any issues.
- Designed for large brake systems found on full-size trucks
- Engineered using technology from Fleet & Military applications
- Ferro-Carbon friction material delivers more braking power and fade resistance than OE pads
- Low dust
- Excellent pad and rotor life
- Virtually noise-free
- Ideal for import and domestic full-size trucks, vans and SUV’s (1/2 ton) with moderate towing and hauling duty

I like them enough that I quit trying different pads about 3 trucks ago
( I do like the PS rotors though, mostly because they look neat and don't rust )
for my trucks those have been my go to pad for many years. with 37-40" tires. my ex weights 9k and my race trailer has weighed 16k fully loaded. ( it is built for that weight and has fantastic brakes of its own )
