If you're like most of the gearhead-types who buy this car, you let the engine run at least a wee bit before driving, so you're not noticing the problem. After 4 months of ownership of my Little Red Hot Rod, I did the deed while in a huge hurry: Started it and immediately backed down my steep driveway. No brakes, I ended up in the street. If a car had been coming it would have been bad. I got the fix and it not only solved that problem, it gave better brake feel overall. Git er done.

 

If you have a SS built after Jan 09 it already has the vac pump and fit.
