Lexus Repair: Brakes, power bleeder, proportioning valve

Question
I can't get the passenger rear and driver front brakes to bleed. I can get them to drip but no pressure. Is there a proportioning valve or something I'm not doing?

Answer
Hello Bryan, We do not normaly instruct on making repairs but what we use is a power bleeder (Vacula brand), they work great and most of the tool companys (Matco, Snap-On, Mac) sell them for a couple of hundred bucks or so. The proper tools will help make the job a lot easier.
