brake problems
before not getting brake fluid to calipers. replaced all flex lines and calipers ( frozen up ). now they wont hold pressure. using a bleeder tool with guage. pumps up and slowly goes down. I did find a leak ( loose line from repair ) but still wont hold pressure and i find no leaks. used proper method for corvette left rear inside first ect... any help appreciated. feel like i am missing something simple. HELP !

Corvette brakes can be difficult to bleed sometimes...one way to do the job is to keep the master cylinder full at all times and push a clear section of tubing tightly over the tip of the bleeder screw on one of the calipers....put the loose end of the tubing in a container on the floor....loosen the bleeder screw a couple turns and see if the brake fluid gravity drains into the container until there are no bubbles showing in the clear tubing.....then tighten the bleeder screw and use the same method on the next caliper....keep the master cylinder full.

Sounds like the master cylinder was not bled successfully. You need the small tubes that hook up to the outlets on the MS and pump fluid back into the reservoir as you pump the piston in the MS while in a vise with a straight blunt tool like a 1/4 inch ratchet extension until you see no more air bubbles-15-20 times. With brake fluid still in the reservoir, install the MS in the car and hook up the brake lines to the MS.

If your power bleeder isn't holding pressure, you probably have a leak somewhere. If you let the car sit for awhile, do you see brake fluid puddled up anywhere on the floor?
