Question about brakes

[yalegolas]

I have a 81' 911 sc that I am slowly restoring, I am looking for performance, but want to be somewhat cost effective.

1. Should I go with metal lines or rubber?

2. Should I need to replace my rotors, should I go stock, drilled, slotted?

3. What kind of pads should I run?

4. Are their any other upgrades / Prevent maintainance I should do I might not know about?

Thanks for the imput

unless you are competing at a professional level .. the SC stock brake set up is plenty ..

The brake's from what I remember reading are "way" more than the car actually needed .. Porsche believes if you are going to go fast you better be able to stop faster ...

As for the lines there are different theory's out there .. stock rubber lasted for 30+ years on your car and a new set would last about the same ..

Stainless Steel versions get DOT if you are getting any you are going to drive on the street (if something happened it would give your insurance an out if they found it)

but eventually it is your car and these are just recommendations ... think about it though

1. Should I go with metal lines or rubber?
If you do a search there is a lot of information on this topic. The cost is almost the same, some people are worried about kinking the braided lines and that the rubber ones last longer, but that the braided ones give a better feel. Really you should change them both after 6 or 7 years and inspect them regularly. Some people feel that braided gives a harder pedal feel. My plan is to do braided on my '73 driver and do the stock rubber on my '86 garage queen when the time comes to replace them.

2. Should I need to replace my rotors, should I go stock, drilled, slotted?
Go solid. Drilled or slotted seems to be a waste of money unless you go with a big brake kit upgrade. I recommend Zimmerman coated as they are awesome and don't show rust as much or quickly as non-coated. They are also quite affordable.

3. What kind of pads should I run?
For street driving I use Jurid's (they make OEM Porsche as well). For more spirited driving I have used EBC green (still a good street pad). For performance the choices are endless.

4. Are their any other upgrades / Prevent maintainance I should do I might not know about?
I would flush the whole system with a good brake fluid and I would also rebuild my calipers at this time.

I ran stainless braided lines for years in Europe. As long as you bear in mind (a) they'll cut through anything they touch if allowed to move at all and (b) they can't be inspected, so should be replaced on a regular schedule, they're great. I have never noticed any difference in pedal feel between stainless and good rubber hoses.

In the US, DOT regulations are written for rubber hoses and stipulate attachments/fittings that are not best suited stainless hoses (do a search). So that's a choice between inferior design/function and non-DOT hoses (which are superior). Then think about the situation you could find yourself in if you use the better, non-DOT hoses.

I chose to use brand-new factory rubber hoses when I upgraded my entire braking system to 996 brakes with a 930 M/C, and it feels like there's a block of wood under the pedal. YMMV.
