In need of doing a brake job on my 911 and need advice.....

[Johnny-5]

2000 Porsche Carrera 911 brake sensors just came on so now Im in need of doing a brake job. Is it better to just replace the rotors or get them resurfaced?

If I was to replace them what brand would you recommend? OEM? Etc...? Also what pads should I go as well?

Thanks

You would need to check the rotors for cracks (between the cross drilled holes) and for thickness.

Minimums are:

front 26 mm

rear 22 mm

I was told by the dealer and by an indepedent shop that I should replace the rotors vs resurfacing them so I ended up just buying rotors. What is your take on this? Have you noticed any performance or issues after resurfacing the rotors? Who do you take it to to resurface the rotors?

Any competent automotive machine shop can easily resurface the rotors, as can many well-equipped service stations.

As long as you haven't worn the rotors down to near their minimum allowable thickness, they should perform as well as new rotors.

Thanks! Good thing I didn't throw away my old rotors, I guess now I have a spare set.

Are these the same for a Turbo?

No, minimum rotor thickness for a 996 TT are:

front 33.5 mm

rear 27.5 mm

Lateral runout of the brake disc, max. 0.03 mm

Lateral runout of the wheel hub, max. 0.03 mm

Lateral runout of the brake disc when installed, max. 0.06 mm

so since the 996 C4S uses the same brakes as the 996 turbo, I assume I use the same minimum measurements?

front 33.5 mm

rear 27.5 mm

Correct - as long as they are steel brakes and not ceramic (PCCB).

Most shops will always tell you that you need new pads and rotors - easy money. I just did my pads on my 80,000 mile 966. The rotors were all at 50% between new and minimum thickness - not even close to needing replacement.
