Troubleshooting braking issues with vacuum pump

2418 Views 9 Replies 4 Participants Last post by  Tom Mobley
Hi all,

After replacing the rag joint on my 67 SS, I went to take it for a test drive. Good news is that the steering is working fine. The bad news is that the brakes were barely holding with me literally standing on them at each stop sign. Needless to say, I ended the test drive early and have the car safely back in the garage. I have an SSBC electric vacuum pump kit installed (previous owner). I'm suspecting the vacuum switch, but is there a way I can verify that? I want to avoid ordering unnecessary parts if possible.

Thanks as always for the great advice!

looks like a pretty clean shot solution. Always nice when there's guys that know what they're doing hanging around. :)
