I am at a loss. This is not my first rodeo bleeding brakes which makes this frustrating. I started out by removing the old fluid from the rear master cylinder. Then filled with new dot 4 and started bleeding from the caliper as usual with all old fluid removed. I refilled to prevent any air in the system and continued bleeding until clean fluid remained. No air bubbles and no lever pressure. I then started from the caliper and reverse bleed still with no lever pressure. I tapped all of the lines, calipers and master cylinder to dislodge any air bubbles and then resorted to leaving the brake lever applied over night with the cylinder cap off but filled with fluid. If a brake bleeding system is in order, any advice on which brand?
Thanks
