[QUOTE="Dan Cooper, post: 1455450, member: 98210"] If I recall correctly, the speed bleeders have a spring loaded reverse check valve ball in them. It's possible / probable that vacuum will not lift that check valve ball against the spring pressure to allow fluid flow. That same feature will also prevent reverse bleeding with a syringe or other reverse bleeder from the bottom up. As mentioned previously, you will probably need to bleed the system the good old fashioned way by pumping the brake lever / pedal with a hose from the opened bleeder to a catch container. Watch out for brake fluid geysers from the master cylinder when first operating the lever / pedal. dan [TABLE] [TR] [TD]Things are never so bad they can’t be made worse. – Humphrey Bogart (as Charlie Allnut) from The African Queen.[/TD] [/TR] [/TABLE] [/QUOTE]
