You guys experience this before? First time for me in 25 years over various vehicles.

Last set of pads were semi metallics that I put on previously (from napa). I guess they were too dense and wore down the rotor along with the pads (pads still had some life in them).





Bought some Centric blanks and Posi-Quiet ceramics from AutoAnything.





Mush harder than I thought trying to find a long stretch of road in LA to bed in the rotors/pads. Two sets of ten 60-10mph heavy braking. Waited for midnight (on a Sunday), slow lane 91 freeway.

 

Had a caliper seize and shread a rotor like that on a'04 and an'07. Motorcraft is good stuff except for brakes. Powerslot slotted rotors and Hawl LTS semi metallic pads. I couldn't be happier.

 

Seized on passenger side and 10k miles later its doing it again. Beware, you may have bad flex lines. I'm changing mine all around and replacing the whole passenger side front... again.

 

Centric makes good products. You shouldnt have any problems with them. I have a set on my truck

 

Just had to replace a seized caliper on my passenger side 07 .... replaced the rotors a long time ago with brake performance slotted and dimpled and slotted on the rear with ceramic pads all around

 

I forgot to mention that I had them on both front rotors (equally worn). It would be strange to have both front calipers frozen nearly at the same time, but stranger things have happened. I'll keep an eye on it if it starts again, I'll look into swapping out the lines and possibly rebuilt calipers. Rear rotors showing a very small amount of ridging...I may just change those to ceramic pads for prevention if it is the density of the semi metallic pad.

Thanks for the feedback guys.

 

DarrenWS6,

Did you replace or fix the seized caliper, and if fixed what did you do?

 

I had a RF caliper seize up. I replaced both front calipers with reman's

 

I bought brand new calipers for the front, left & right, from the dealership. Best to replace in pairs. Painted them silver while they were off the truck.

 

I should have painted mine when I bought them. Good advice here. Paint them before installation

 

That problem has existed since they came out with the NB in '04. I have owned new Ford trucks before and have never had the kind of rotor grooving that the heavier NB has. To compound it, the So. Cal. stop and go doesn't help at all. I wouldn't be surprised if Ford gets the rotors from China. There are a lot of other Chinese made parts in our trucks. The rotors are just plain soft metal. I think they were old beer cans in a former life.

 

When I had my 2005 F-150, I posted in here about how I thought the new body style (for 2004) trucks had junk / undersized brakes. My logic? I've driven F-150's for years and always got at least 60,000 miles out of front brakes and 80,000 miles out of rear brakes. On my 2005, the rear brakes (rotors and pads) were absolute junk at 23,000 miles. The fronts followed at 27,000 miles.

So what did I hear? All sorts of idiots saying I must be riding the brakes and there was absolutely nothing wrong with the factory brakes. Funny how replacing them with higher quality pads and rotors allowed me to get almost 40,000 miles out of the second set. Oh, and not too long after I replaced the original pads and rotors, both front calipers seized up, so they were both replaced.

My current 2010 F-150 - which is an exact duplicate of my 2005 - currently has 43,000 miles on it. And, the truck came with significantly larger front brakes. I had her up on the lift this past weekend and the brakes (all the way around) look like they'll go another 20-30,000 miles. You draw your own conclusions.

 

It does make things much easier.

Here are a couple pics from my brake job.

 

Well i got over 75k on my front brakes, and the rears are still good after 90k, so what's your point? My calipers are original and i only replaced the front rotors in order to do the centric conversion to 4x4 versions.

 

Wonderful. Yet another slap in the face. You might notice that your truck is apparently a 2008 - which is several Engineering Change Orders newer than my 2005. That might explain your better brakes.

Getting back to the point I was trying to make, the brakes on the newer trucks are significantly different / bigger than what came on the earlier trucks. Smaller brakes equal harder working brakes. Harder working brakes equal more brake wear and heat. More heat leads to issues with "soft" components (seals, sliders, etc.) in the calipers. And that's the stuff that goes bad and causes one to replace calipers - usually after they seriously overheat a rotor. Get my point now?
