Review on 🔧 ACDelco 178-0931 GM Brake Booster Kit: Vacuum Power with Grommet and Gasket by Ryan Gillett

Well I was looking for a brake booster that matched the bolt pattern in the firewall on my 1983 and later Mercedes 3 Months of testing for others at every parts store nearby and on Amazon. Got this one and it was 100% the same as the one I removed except for the master cylinder bolt pattern which I ordered a 2015 Colorado master cylinder booster to go with and now I have great brakes. They only made 11,000 Mercedes 380sl 107 Roadsters in 1983, the power brakes were $1400 if I could find one at all. Very happy.
