SC brake rebuild upgrade
 

I have never touched the brakes on my 82 SC. They work good, but I think it is time to go through the entire system. I plan on changing all the existing rubber/flexible lines.
Also considering upgrading the front brakes to the wider 84 up Carrera rotors and calipers and just rebuilding my rear SC calipers with a set of new rotors.
Any thing I need to know and order before I start on this project. I would like to have everything on hand before I start this project. Any and all info appreciated.

If it ain't broke don't fix it. Just change the rubber lines if they are old and flush the fluid, check the pad/rotor thickness.

My understanding is that SC brakes are already over powered for stopping an SC. Upgrading to different rotors/calipers doesn't accomplish much. But replacing the rubber and wear parts sounds like a wise plan, especially if you don't have records of when it was last done.

That makes sense if you have increased hp by a great deal....otherwise stock is more than adequate if in good shape.
You can 'over brake' and get a twitchy and break away/lock up situation.

Do the maintenance and leave the rest alone. Slotted or drilled Zimmerman or ATE rotors are a good idea.

PMB Performance does a great job rebuilding calipers, they look and hold up better (the crud you see on your calipers is actually corroding them) and not too big a job to DIY

+1 on new rubber lines, check rotors/pads and change if necessary

I just upgraded my pads to more track oriented units. I'm stunned at the performance of the basic stock components. It's a very good system for the SC, I wouldn't waste my time upgrading the front rotors / calipers if the rest of your car is basically stock.

I put the early Boxster fronts calipers on with 3.2 rotors 12 years ago.

A different feel. Can't say they brake better as have never worked either kit hard enough. Have swapped them on and off again.

I say put the hoses on. Flush and do everything you can to get every spec of air out. Getting the air out was THE biggest step change in my brakes I have experienced. Before and after the Boxster "upgrade".

If you go the 3.2 route, and I am just talking, do the whole nine yards if possible, including master cylinder.

Make sure you replace the calipers with the bleed valve up! (If you swap them side for side by accident, the bleed valve will be down - which is bad.)

Thanks for all the responses. However, I failed to mention in my original post that I have installed steel turbo flairs on the 82. I also increased the wheel size to 17x9 on the rear and 17x7 on the front with larger tires all the way around.. I love the turbo look of a Porsche.

Since my original post I have secured and rebuilt a set front and rear of Carrera calipers. Ordered new Carrera vented Zimmerman front rotors and a set of emergency brake shoes for the rear. Figured I would replace them when I had everything apart.

Question - What rear rotors do I purchase. Carrera or SC.

Thanks again for previous responses. I am not a rookie at building cars, but a rookie at building a Porsche. I do have a complete set of factory Porsche manuals to help me along the way.
Thanks again.
