I am having some of the same problems bleeding my front brakes after changing the pads and mounting a new rotor. ie. cant get the spongyness out of the brakes. I ran almost 12oz of brake fluid through the system. Used the mityvac and then tried it the old fashioned way. Before I try some of the tips I have read, ie letting the caliper dangle, my question is what is on page 6 of the forum that keeps getting referred to. The thread I am reading only goes to page five.
Thanks,
Ted
