I drive a 2004 Hilux Raised Body Double Cab 4x2 (difflock) with 3.0 Turbodiesel engine.

Only have one problem. When driving it down at sea level the brakes keep on binding. It feels like you are pulling away with the parking brake applied. You need to hook your foot behind the pedal and pull it forward to disengage the brakes. Problem not experienced when travelling at higher altitudes.

Anyone experience this and is their a solution? Has the Toyota techies baffled.

First thing I would do would be to bleed the brakes. Maybe something with the air densities at sea level and high up are causing problems? And, if that is the case, check for tiny leaks, or your proportioning valve if there is one. I had a problem with mine on my 87, but, it's an 87, I don't know about 04's. Good luck.

Thanks. I'll try that. The Toyota agents tested the proportioning valve (load sensing valve) when I first experienced this and found it to be in order. What should one check on this valve? For leaks?
