I just tried to power bleed the brakes (front discs) on my son's 67 Camaro. I started with the closest to the master cylinder , in this case the left front and then the right front. After I finished I put the front tires back on and found out both front brakes are locked. This is first time I used the Mytivac for this purpose and ran into this problem. I don't have a Camaro manual but I do have a 73 Nova manual. In that manual it states one must hold down the metering, proportioning and failure warning switch. Unfortunately the car is 15 miles away and I can't look at the system. Is there a similar valve in the Camaro system?
Thanks
