Good afternoon everyone! I need your help. I just got my Land Cruiser back for almost a year and no expert on much. I was trying to bleed my brakes earlier and the rear brakes weren’t bleeding. I did some research and found out that the LSVP can clog it up or something. I don’t know much of it so I need some of your knowledge. My brakes are super spongy literally hitting the floor so I need to fix it asap. Thank you everyone! I have a 1991 Toyota Land Cruiser fj80

I don’t see the LSPV clogging it up. But if a lift is installed the LSPV can greatly inhibit braking and pedal feel if not addressed
I have every reason that I bled mine for the first time since the production line. Fluid was black, no trace of any wetness under the rubber boot. Seems to me to be fairly trouble free device unless the actuating rod is moved or lift altered.
It sounds like you’re saying this is a new problem after the car has been siting for a while. More than likely you have a brake master cylinder that is leaking internally. You should replace it.
If the brake fluid is not coming out of the bleeders at the caliper, close the bleeders back up and try pressing the brake pedal several times to see if that helps. Then open it back up to see if it flows out.. if that doesn’t work try pressing the brake pedal with the bleeders open. You could have debris clogging up the brake bleeders. You could also remove the brake bleeder.
Lastly , if you don’t have one yet, spend the $100-$200 to get a motive power brake bleeder tool as well as power probe adaptor. With these, you can keep a constant 15psi through your brake system while you bleed the lines.

LSPV will need to be replaced if its original. Its pretty much impossible its working properly for how old it is.

@JimmyA23 When you say you can't bleed the rear, what exactly are you doing when trying to bleed the brakes. There are lots of threads here and most end with using a pressure bleeder. Ask me how I know 
. Before replacing any parts you might want to invest in one. The reason I say this is, you'll probably end up buying one IF you replace parts. Some of these trucks are a down right pain in the 
to bleed. So, if you have to open everything up, a pressure bleeder will be your friend. Best of luck!

This is what I used. It worked well. There are others too.
