I've had brakes from you in my cart at least 4 times and haven't had the courage to buy them yet. I bought the brakemotive stuff and have been very unhappy with them, so I'm hesitant to take the leap on an unknown again. I'll be sticking with regular rotors and semi metallic pads this time.
The brakes arrived today so I can answer half of my original question. The semi-metallic pads are rated FF. This is the same rating that the Hawk LTS pads have, which doesn't mean they're equivalent, only that they're in the same ball park.
Here's an interesting shot of the Nakamoto rotors. There is an obvious casting seam between the two halves that isn't exactly heartening. On this rotor it's like this all the way around, on the other it's far less dramatic.
I have zero clue if there's any significance or if this is merely cosmetic as this isn't a subject I'm any kind of expert on. So I'm going to try to find an objective expert opinion, but if your group has any input on this @1ATony it would be very appreciated.
Well most any cast will have at least 2 halves and some have multiple sections, so having a seam doesn't mean it's not cast as one piece. I'm 99.99% sure this is still cast as one piece.
What I'm not sure on of course is the exact casting process. I don't know if there are 2 simultaneous pours that meet in the middle of the vanes or one pour for the entire cast.
If it's a single pour this is possibly just core shift showing the seam but it's still a solid piece through the vanes, no worries.
If it's not a single pour then it's possible there's a situation where the metal wasn't hot enough during the cast and by the time the pours met they were too cool to properly join as a single piece. It would be similar to a weld that's too cold and doesn't have proper penetration; they're stuck together but the bond isn't strong.
I can't say as I've ever looked that closely at the vanes on every rotor I've seen, but that doesn't look right to me. If the caliper isn't sliding freely - which is a very common thing on these trucks - the unequal force applied to the faces could cause it to shear. I think you're right to be concerned.
I recently changed front rotors and pads on my '02 and '04 Excursions. Used Hawk Sector 27 (drilled and slotted) Rotors and Hawk LTS pads. The change went smooth and so far I've not had any issues with them. Stopping in the cold has been great. I haven't noticed any appreciable dust yet. Only about 4 months on them so far, but we drive a lot of miles. Right now the set of both is $220 on Amazon, but when I bought them, it was $185. The Hawk pads don't come with any of the hardware (springs, clips), so you might consider picking up a hardware set from O'Reilly or Napa unless you know your springs and clips are good.
jpanask - you still happy with the section 27 rotors? The kit on amazon is still priced well:
I am still happy with the Hawk brake sets on both of my excursions. The set comes with two rotors and 4 pads, along with some break grease. There is a front set and a rear set that can be purchased separately.
Cool. Thanks for the info. I was thinking of going with the LTS pads and the Powerslot rotors, which appears very popular. But this deal is very intriguing....
I just picked up a full set of power stop brakes, rotors and calipers. Front and back, the z36 set up. Hope I did ok. I was gonna try and get the russell lines to go with but 4wheel parts did not have them for the excursion. I guess I will get them later on. I got the kit for what seems like a really good price. Hope everything goes on easy.
