spongey brake petal
Hello, I just replaced all the rubber lines and hard steel lines on my 02 Tahoe.pedal hard and won't sink down when not running.start it up no petal right to floor.ran a full bottle of fluid thru the system and no bubbles when bleeding . Any ideas ? Master cylinder? Changed out dirty reservoir .before adding fluid.

also, If the system has a proportioning valve; a special tool is required to release the valve for bleeding the rear brakes. when you develop a fairly firm pedal...have a shop perform an automated system bleed with a scan tool.
the trick when replacing brake lines and flex lines is to never let the m/c empty. slightly depressing and holding the brake pedal with a pry bar will close off the ports in the m/c so fluid will not drain.
