I'd remove the brake pads and caliper bolts without cracking the brake lines and carefully get a good look at the caliper piston seals.
Look at the flexible lines too. If they all look good (not cracked) put everything back and bleed the system and drive the car. Brake lines swell on the inside with age, if they have not been replaced they should be.
Rebuilding calipers is always a good idea as Landseer said if within your ability.
But you did say it stops well..

Thanks the fixer, lll start narrowing things down this week (hopefully)

Camo, looking at your sig, 1982 Porsche 928-hellbronze metallic auto , did anybody ever check to see if its a Weissach? They were that body color with a two tone interior.

Danglerb, My interior is just ugly brown

So, I've noticed my car shifts a little hard, I'm thinking I should get the transmission checked. Is it pretty involved to check the fluid?

I have seen a few cases where the vac line was either missing or severed for the transmission modulator. Follow the metal vac line at the front of your intake to where it is fastened to the engine at the rear of the right cam tower. Check the condition of the rubber line that attaches to it. You can also adjust the modulator easily. Details are outlined in the WSM.

Checking the fluid is easy. The reservoir is mounted at the right of the transmission case. Kneel down in front of the right rear tire to see it. It is small, so it is easy to overlook as it is usually coated in grease. Here is a good guide for checking the fluid. The Nichols page is a great reference. Bookmark it for the future.

Thank you kiln_red! I'll check that tomorrow (hopefully)

Remember to have the car up in temp and running while checking the fluid. Make sure the car is level and have a piece of cloth ready to whipe the reservoir with :)

Hey, after doing some searching I am starting to wonder if I might have a Weissach. I doubt it but you never know.
I always thought that mine could do 0-62 faster than 8.5 seconds. If I understand correctly, the Weissach (how do you say that?) does 0-62 in 7.5 sec.
Anyway my interior is similar to this one.http://forums.pelicanparts.com/uploa...1358271947.jpg

I have the VIN but I dont know where to look it up. If anyone could help, VIN is:WP0JA0927CS821644

Like i said, I doubt it is, but it never hurts to check.

The Weissach was strickly a cosmetic option. The difference in acceleration may be 2 different tests, one of a manual and one an automatic.

Oh ok. I just read that somewhere on the internet.

If you have pieces of the luggage with the car, it might be important.

No I don't have the luggage.. Also there's no crest on the dash.I noticed that's mentioned in the link dougm shared

How can I find out if it is a Weissach or not?

Camo,
There were only something like 205 Weissachs made. I believe that it has an option code. Email roger@928sRus. He has a couple of them and can run your VIN # to check.

Roger might know, 200 or so planned, but actually more than 250 going by vin I think found, maybe as high as 275. Option code is

M462 928 - Special Model 82 "WEISSACH" - Hellbronze Metallic w/Leather Medium Brown Int.

Great thanks guys!

Well there you go!! I knew there was an option code for it, but I didn't know the number. I figured one of the resident gurus would know and speak up.

So Camo, if your car has that option, then it is definitely a Weissach.

Thanks Danglerb.

I looked in my warranty manual and under optional equipment. The option number danglerb gave is not listed

According to Roger, I DO have a Weissach. I picked up a Weissach for $2,500 :D
Now if only I had the luggage...
