soft break pedal with full travel

Proper bleeding sequence is farthest to nearest (to the master cylinder), so driver rear, passenger rear, passenger front and driver front, followed by the LSPV over the passenger rear inside the frame rail. I often deviate a bit and to the LSPV after the passenger rear brake since I am there and have the vacuum brake bleeder all set up and ready to go. I've only bred brakes once with the 2-person technique so an no expert at that. I find the vacuum (or pressure) brake bleeders work fine for me.

Roger up here in Nova Scotia everything rusts that's the reason why I replaced the rear brake cylinders "but" the overload proportional valve's (or load sensing valve) bleeder screw is completely rusted seized which means that if I mess with it I am going to have to buy a new one from Toyota for $240 CDN plus new brake lines,can I bleed the system withouth messing with that overload proportional valve?.Thanks.

You have to continue pumping the pedal until all the air is expelled. Usually more than 4 pumps. Using a glass jar to catch the used fluid makes it easy to se when the air is all out.

I've always bled the LSPV when I do my brakes, so I don't know what happens if you don't bleed it. It can affect both front and rear brakes. It does have a two pressure lines to it, one with the main rear brake fluid and the other from the front circuit that senses if front pressure is lost. You can replace the LSPV with a lower cost adjustable proportioning valve (you lose the load sensing part of the valve). Wilwood makes a valve that costs about US$40 and there is a full kit to bolt in place of the LSPV for US$70:
