For those of you that are bleeding brakes and are having trouble getting them started, grab your favorite color balloon, or condom ( for those that have-not been cut ) place it over your shop vac, and place over the bleeder valve, I saw it for the first time today and it worked great, they hit all four wheel cylinders in about a minute, finished up with a manual pump ( foot ) and was done in ten minutes total. Note ( not responsible for the impromptu looks from your other half )
