My brakes are squealing now, too. I find that when my pads get low they start talking. They still have plenty of miles left on them, though. If the squealing starts to bother me (and it already has) then I'll change them...but not because they've worn out.

Would you change pads without resurfacing rotors?

mgordon18

Ab. So. Lutely. I won't replace the rotors until they're worn past the wear indicator or if they have cracks spreading from hole to hole or out to the edge.

I would just change the pads and bed-in the new ones on the same rotor.

Edit: You asked about resurfacing and I said replace, but the same statement holds for resurfacing, at least for me. I've had no issues so far, and I've gone through lots of pads, particularly on my rear axle while still on the original rotors.

Changing just pads and not rotors is very common for us track junkies. If your rotors are still in spec, I'd just throw a new set of high quality street pads on and it will probably solve the issue. Swapping pads is very easy DIY and takes about 6 minutes a corner once you have the wheels off.

If you have a 997 it takes 6 minutes a corner. I wish it were as easy on a 991. The 991 requires the entire caliper to be removed, to change pads. From start to finish for a street to track swap, including track rotors, I clock in around 90 mins. Plus the caliper removal process just introduces unnecessary, increased risk of cross threading the caliper bolt, which I've unfortunately done. What's even more difficult is a caliper rebuild (link to my walk through here)

911.

I think its a bunch of BS there are many manufacturers that use the same brakes that Porsche does that dont make any noises. Chevy for example...

first time you do your own brake job, get the caliper stud kit and the brake line stud kit from Tarett. Yes, first time a little longer but next time so much easier

OMG. This is amazing. I didn't even know these kits existed.

I just received Centric PosiQuiet pads for my .1 4S. The fronts did not include a hardware kit, while the rears did. Anyone know if there is additional hardware needed for fronts besides just the replacement pads?

I bought these:
Fronts
Rears

Just replaced the pads in my 991.2 with Posi centric. My pads came with the hardware. I replaced the rear hardware but left the front existing hardware in place because it seemed like a pain and the old hardware looked good. Brakes work great with less dust. You may want to have replacement sensors on hand because they break easily.

Awesome! I'm doing this with my next brake job!

BTW, in addition to the above, I'll add that Porsche OEM rotors don't have a lot of extra thickness to them, so that after going through a set of pads, there often isn't enough material to have them machined. Instead, if they're within spec., I just throw a set of pads on and figure on replacing the rotors when they wear out. As for pad choice, I like Porterfield R4S over Centric Posiquiets. They're pricey, may give some noise unless bedded, but have far better performance.

Starting to assemble parts for a front Brake Service on my 991.2 base w 26k miles. Rotors are lipped and pads are...worn; can’t quite tell exactly, but there might be 4 or 5 mm left. So, soon.

OEM rotors and pads ordered from Suncoast, the few remaining parts from Pelican. I plan to DIY in my garage. I’ve done Bimmer disk brakes before, but I’m no pro mechanic. I just take my time and work through it.

What pad spreader do you guys like for opening up the pads in the Porsche calipers?

I was going to go with this simple one, unless there was some particular reason not to:

That's the one I have. Works well.

Do the rear brakes require the electronic parking brake to be retracted using software (like Audi and VW) in order to change the rear brake pads?

Bob Z.

Nope, not required.
