VW Quantum master cylinder. We only carry original equipment quality, direct fit master cylinders; you don't ever want to skimp out on brake components. The master cylinder is responsible for converting your foot pressure into stopping power for your vehicle. If your brakes feel spongy, or the pedal is progressively getting softer it is time to replace your master cylinder, before your car no longer stops at all.
Flush fresh brake fluid through your brake lines when you change the VW Quantum master cylinder. Never try to reuse old fluid, over time it draws moisture from the air and then can't handle the heat generated while stopping. When you bleed your brakes after installing the master cylinder, make sure to inspect your braking hardware. If it looks like it’s time for new rotors and drums, look at the kit below to get all the parts you need for your VW Quantum.
