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.

Don't do this for a living!
I did do rear pads on my wife's Grand Cherokee a few years ago in less than 20minutes, start to finish. This including rolling the jack in place and putting the tools away. I came home from work and wife said dinner's on in 15 minutes. With a busy night ahead, I worked as fast as I could and was washing up as she was puting the food on the table. It helped that I had done it before and knew without looking exactly what tools were needed.

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've swapped pads between OEM and Pagid Orange about 8 times. I've never replaced or cleaned the dampers. With the stock pads the brakes don't squeal at all - ever. With the track pads they squeak but that's going to happen with new dampers or old dampers.

By "tweaked" do you mean damaged? If that's what you mean saying this happens "offentimes" is really wrong. If the damper is damaged so badly that it's sticking in the piston bore, of course it should be replaced. But telling someone to replace an undamaged damper is like telling them to replace a pad before it's worn out.
How could you even damage a damper? The only way I could see it happening is while carelessly compressing the piston - and that could happen just as easily with a brand new damper before you install the pad.
I don't claim to have seen every brake problem under the sun but I've changed pads lots of times and I've never seen a stuck or damaged damper. Please enlighten.

I've never seen dampers stuck to the pistons. If I were doing a full brake job with pads, rotors as the OP intends, I might replace the dampers also on general principles.
Changing pads can be done quite simply without removing the dampers at all - hence they won't be sacrificial. I suppose if I noticed they were stuck and not moving freely I'd shoot some brake cleaner in there to see if they loosened up.
Van's DIY video they don't replace the dampers - or even mention them:

Oftentimes I never spell it offentimes -
Get those dampers out for trackpads. New ones for OEM pads acc'd to Porsche.
I'd surmise that Van has consumed caffeine early in the video which has thenceforth worn off.
You can see there are no dampers in his video.
Cheers!
