Hi

Been having issues with my brakes coming on and stopping the truck. It happens on left and right at the front. My calipers are ok and I've bled all four wheels and also the master.

I've been trying to find any other 60 that has this LSPV valve mounted to the front brake booster just below the master cylinder. I can't find anyone who knows anything about this valve. Here is a pic.

Does anyone recognize it? Is it from some other toyota?

Thanks

I havent seen one there. But I dont think that is a Load Sensing PV because they need to connected to the axle to alter the pressure as the suspension is loaded and unloaded.
But I do know some 60 series have a proportioning valve that stays fixed once its set. No load sensing feature.

It is most likely year and market dependent.

My 89 Fj62 has it, my Hj61 has it, I bought a master cylinder seal kit and there were left over seals, would they go into that proportioning thing?
My brakes are s*** and have very low pressure and sometimes don't work, that is the only thing I didn't touch.
