I didn't have a chance to test the compression tool but it looks promising. About the bleed kit the vacuum pump works realty intermittent opened it up and discover that the piston is really low quality and the o-ring didn't fit tight enough this explains the intermittent pumping. The adapters that go over the bleed port are made from some type of soft nylon and they don't make a good seal especially in Canada they became very hard once they got a bit cold the same thing is for the hoses. So if you are in Canada it will not work for you . You need to wait for temperatures over 20 C in order for the kit to work. I would have return it if Canada post was not on strike.
