Ready to do front brakes...
I am ready to order 2 new OEM rotors, a set of OEM front pads,new rotor screws, a front caliper spring kit, 4 new caliper bolts. Do I need to order the vibration dampers(4) and new sensors(2)? I have a friend who bought my 79'SC a few years ago who has a Porsche brake piston compression tool that should make this pretty easy. I've watched Van's video and will be ready to go as soon as I order my parts.
So, is there a need for sensors and dampeners when I do this? TIA.MY99 coupe with 56k miles,on 2nd set of pads and original rotors. Last winter I did the front brakes on my GMC pickup and it was very easy, so I'm hoping this will be similar.

The sensors should still be good as long as they haven't contacted the rotor. It may be a gd idea to get the dampeners just for the sake of peace of mind,because often times they get ruined when trying to get them off the old pads. Overall pretty straight forward job. Maybe a 3 out of 10 in difficulty. IMO

Steve......like Eric said if the sensor didn't contact the rotor (or the brake idiot lite would be on) I would not bother. But they are only $10....The DIY is really straight forward. Make sure you zip tie the caliper to the strut and have the correct bit for the caliper bolts. T-25? 1-2 hours tops.

I replaced the calipers, rotors, pads, dampers, sensors yesterday on my wife's 99 996 and it was pretty straight forward. I did replace all the sensors and you should definitely replace the dampers in my opinion. In the front you will need 4x 996-351-088-01 (2 per caliper), in the rear you will need 4x 996-352-086-00 (30mm round) and 4x 996-352-086-02 (28mm round).
Good luck with the project!

Steve, the first time I did a front brake job on one of mine, I skimped and did not buy the new dampers. Save yourself some frustration (and squealing brakes) and get new dampers. Good luck.

Thank you all(Ericginpa, Pete,Axeman,Van, and Mark) for your input and advice. I just didn't want to duplicate parts that I didn't need to. I'll place my order tomorrow and hopefully in a few days my Porsche will be ready to play safely again. Funny, this afternoon my oldest son came over, and thought it was pretty cool that I was tackling yet another Porsche project. Thanks guys.

One more observation. I did my brakes (front pads and rotors) last week.
The older caliper bolts use a 10mm hex socket. The new bolts use a T-55 torx socket. Torque them to 63 ft/lbs. I had a buy this large torx socket at Pep Boys for around $6.
I could have used the old sensors because they did not break through. However, I could not pull them out of the calipers and pads without breaking the small clips; i.e., I could not press the small clips to release them from the calipers. Thus, I was glad I bought all new parts except the main pin, pad retaining spring/bracket and cotter pin.

Barn.... if you can't get the little screws off on the rotors, there is a tool that you use a hammer with to untorque the screws. Works everytime for me. When putting the screws back on... use anti-seize. Let us know how you make out.

I had negelcted to order new dampers, so I cleaned my old ones. I used brake cleaner and a scraper knife to clean them, and it only took a few minutes.
The reason I would recommend buying new ones is that it was a pain in the *** to find a replacement adhesive.
