This brake job is costing me $4,800 just for the parts. (My labor is free, which is about what it's worth.) No, that's not $4,800 for brake pads and turned rotors--your standard "brake job." Even Porsche parts aren't that overpriced. What I have waiting in my little cellar workshop is an entire new brake system: huge front and rear four-piston Brembo calipers, massive cross-drilled and vented rotors, a Turbo Porsche master cylinder, vacuum booster, brake lines, high-temp brake fluid…most of it originally designed for the 1,100-horsepower Porsche 917 Le Mans and Can-Am car.
