958.2 front brakes
just purchased a 2016 base. The front brakes were replaced when I bought the vehicle (non Porsche dealer). They squeak pretty badly at parking lot speed otherwise no squeal. I tried tracking the paper work and see what brake pads were used but there were no mention of the part number. I'm thinking about replacing it with something different. Which pad should I get? EBC? OEM? Hawk?

I recently replaced mine with Pagid pads, which are the OEM supplier. When comparing the old (Porsche) to new, the parts were identical. Price is much lower, of course. I think I got mine from Pelican but shop around for best price. They have good bite, no squeal and a normal amount of dust (some, but not excessive).

I like both Hawk Ceramics & Hawk LTS pads. You can probably resolve your squeal by removing the pads and adding some Permatex pad backer anti-squeal goo to the backside where the piston contacts it, or by installing the proper Porsche pad dampeners which are adhesive pads with a metal prongs. The adhesive sticks to the back of the brake pad and the prongs lock the dampener into the caliper pistons. What causes the squeal is a harmonic vibration between the back of the pad and the caliper piston, not the face of the pad and the rotor. Once you affix the caliper pistons to the back of the pads, the noise will go away.

thanks for the reply. I think the dealership that replaced it, used a cheap brake. It is leaving brake dust like crazy. I have to clean the wheels weekly to keep it from turning black. The dealership willing to make it works, so I'll see if changing the pads will be a better solution.

Change Pads + Rotors?
I recently had the pads replaced by my local guy on my 2012 958TT. They squeak like crazy. Now, the dealership is telling me that I should have replaced the rotors at the same time (rep told me it is a very expensive proposition; no exact figure, but said he recently charged $3400 for pads/rotors on a 2005 Turbo!). Does anyone have experience with having to change both pads and rotors and, if so, what did it cost you, appx?

Turbo rotors are pricey - Turbo S rotors are super pricey.

1. Try putting brake grease behind the brake pad, where it touches the caliper piston.
2. Remove the transfer layer from the rotor which formed by the previous set of pads. This involves either sanding off the transfer layer using garnet sandpaper, or a more extreme measure of turning/machining the rotors to achieve a smooth surface.

Reply to post re pads + rotors
Thanks for the feedback, guys. I'll run the information past my local guy, who originally said the rotors were fine. And yes, from looking online (Suncoast, etc.), the Turbo rotors are expensive (what else is new).

Who is your local guy? I work in Los Gatos and live in Milpitas, and would like to be able to take my car someplace other than the stealership. Have your experiences been good with this local shop?

You might look at TRW pads if greasing the back of the pads doesn't help. You can get them from Amazon.
