I restored my very first vehicle brakes while still in high school in 1983 and lived to tell the tale. Since then, I have continued to take college classes cover- ing many automotive systems, including brakes. The biggest brake job I was in- volved with was a 1923 Baldwin Steam Locomotive back in the 1990s. Yes I said train. And yes, you can stop a train!
I like brakes. I’m even employed as a Conductor/Brakeman on the BNSF, and have been since 1997. Not a day goes by that I’m not inspecting some sort of brakes at work.
So when my Porsche 928 needed a refresh to the brakes and suspension, I took the brakes by the horns.
Stomp On’em If You Got’em!
9T28 BRAKE UPGRADE
o brake or not to brake is the big I was experiencing sticky brakes on question. Newton’s law states that the front wheels. Upon inspection, what objects will remain in their state I thought was original, was not. It turns
placed with GTS large Brembo calipers and 993 Turbo rotors. Bonus!
While they were an upgrade, they were old and tired. The first brake parts that definitely needed to go were the flex brake lines. Don’t skimp on this part. Buy a high quality brake line. It’s critical to deliver the brake fluids to each wheel cylinder or calipers. I inspected the hard brake lines as to their condition. Are they corroded, bent, or leaking? For me, it turns out I found a kinked brake line connecting the front brakes just off the master cylinder that I fixed by making a new one from stock copper line avail- able at any parts store. Otherwise, all my brake parts came from 928RUS. They are very knowledgeable about the ins
of motion unless a force acts to change out that my old 1985 brakes were re-
the motion.

I inspected what I thought was original ... turns out it was not.
