1967 Corvette Brake Bleed troubles
Hi Guys,
I just installed a brand new SS brake system. New lines, master cylinder, and brake booster. The master cylinder is from Lonestar.
I'm having problems bleeding the brake. It does not seem the fluid is flowing out of the master cylinder.
I have it connected up and i am using a handheld suction device to pull the fluid from the master cylinder to the caliper.
What am I doing wrong. I can seem to get any flow out of the master cylinder.
Kind Regards,
Daryl

I never had any success with any of the suction devices. I use a Motive Power power bleeder, and it'll bleed any Corvette disc brake system in ten minutes.
Did you bench-bleed the master cylinder first?

and I will buy one of these the next time I do a full brake job.
However, for almost 50 years of doing brake jobs on cars, I have always had success doing it the old fashioned way, with the girlfriend or wife pumping the brakes while I turn the wrenches.
My wife of 42 years knows the brake bleeding procedure better than me.

Had a master cylinder problem on my 67 convertible and after bench bleeding the new unit we tried to bleed the individual calipers. Tried the old method of open-pump-close with no success. Messed around for another half day and finally took my friend's advise and gravity bled each caliper. I was shooked to find that I had a firm pedal. Jack the car up all around and put it on stands . Open the bleeders and place a pan under each caliper. Make sure you don't empty the master. Good luck.

Take JohnZ's advice. I had the same problem you do now. I tried with my wife pumping the peddle. We performed that operation 3 times and I never got a firm peddle. Went to the Motive Power Bleeder and got the adapter for my 66 MC. Bled the system by myself and had firm peddle for the first time in 20+ years.

Did it for the first time using the Motive tool on the complete system overhaul of my 67 this spring. I would never attempt it any other way again. Less than 30 minutes to do the entire job, including bleeding of the MC on the car (no need to bench bleed it).
