Do the Porterfield's reduce the brake dust.? The stock brakes are horrible for dust

Just put Porterfield street pads on my own Vantage in September. Significantly less dust; definitely squeal. I will be rectifying the squeal with some anti screaming goop in the near future I think. At the same time, it defeats Doug DeMuro's problem of people not noticing that you're driving at Aston, so I got that going for me now.

So, I have a 2007 V8V with 2,300 miles. The brakes squeak and it drives me crazy. After the brakes warm up, the squeaks go away. Still..... I read a lot of good reports about using BG Stop Squeal. so, I bought 2 bottles and soaked the pads in a pie tin. The stuff worked for about 25 miles and then the squeak returned. This winter I plan to install a set of Porterfields that the guy at Red Pants seems to like.
We'll see in the spring.

Ahh..I Googled skimming brake disks. I guess that might help in some instances. In my case, I've only got 2300 miles on the car and the disks are pristine.

A lot has been written about the need to bed in new brake pads / rotors to prevent or eliminate squeal. It is not clear why this is needed. Before I retired, I was in the auto industry and I can tell you that auto manufacturers do not do this to new cars. Over the years I've owned a lot of cars and the only one with squeaky brakes is my V8V. I've probably done a dozen of so brake jobs and never bedded any of them.... no squeals. So there must be something else goin on here. Clearly people have this problem with other cars too based on the number of products on the market purported to fix the problem. I don't claim to have a solution, I'm just looking for one.

Try using the brakes like you stole it and are outrunning the cops. Use them hot and heavy and see what happens. You've got nothing to lose. I suspect many of these brakes are glazed due to light use.

Once again, Steve McEvoy has the information we need. Apparently, different brake pads are bedded-in differently; here's the Porterfield procedure (which worked perfectly after I changed mine): https://aston1936.com/2019/10/24/bed...age/#more-4093

i removed the OEM pads from my 2007 vantage v8 and bought some very inexpensive EBC pads from ebay, then applied some copper based grease on the interface between the metal backing plate of the pad and the brake pistons. it is still quiet after about 10,000 miles. did the same and worked on my porsche cayman too.

i know better than to waste good money on brake pads for street use.

I recognize that you may not have meant to be cavalier about this, but.... tires and brakes are the most important safety aspects of a vehicle. These are two places that I will not cut corners to save a few bucks for both my own safety and of those around my vehicles.
