Power Steering pump issue HELP!
Hello, I have a IFS 91 pickup truck with the 3vze, 3" body lift, 3" bj spacers and 35x10 SS (I am pointing the mods out just in case it is neccesary for your recommendation) . Before adding those mods my factory steering pump broke, so I bought a cheap one on ebay, and it is broke too, so I took the truck to a mechanic shop and the guy culd not find one that would work because it would broke almost instantly, so, I would like to know where I could fine one that works fine or if due to my mods I should adapt another one, or which one do you recommend me to use. Thanks a huge lot for your help.

Did you mean "brakes a whole lot?" if the axle seal is leaking you should fix that first and replace the oil soaked brake shoes. they pick up brake dust and become very "grabby" when coated with gear lube or brake fluid and you can never clean them enough once they are oil soaked.

I have never seen anything similar happen except with a bad batch of replacement parts. I assume in that case they hired a new guy and he messed up a lot before they mended his ways (this case was with alternators). The parts guy was a friend of mine and he told me later (months after I upgraded to a higher quality part) that after 4 or 5 failures on exactly the same part they seemed to work through the bad batch and all was good from then on.

I mean that when I slightly step on the brakes there is a rear tire that completely stops instead of a soft stop. My axles are fine, the mechanic found what the issue was, and it is a piece that distributes the brakes fluid between the rear tires. I do not know how the name of the part would be in English, here in DR we called it "repartidor". The thing is that we certainly know because the part is leaking brake fluid and I hoped that somebody could know where I could get that part since I have not found it on eBay.
Doesn't matter what you or I name it, only matters what Toyota named it.
You are maybe talking about the LSPV (load sensitive proportioning valve), this is attached to the frame.
There is a distribution block, splitter, tee connection attached on the axel.
Lspv isn't available.
The other part can be cleaned and remounted, it just joins the three lines no mechanical guts to it.
Alaskans statement still good, you can't be sure it's not just bad/dirty pads untill it's clean and dry, unless you've checked brake line pressure at both brake assembly at which point you want to make sure it's not the lines and need to work your way along the system. Pull it apart clean it up and see if it will hold a seal, then put clean shoes on.

What are you using for power steering fluid? Most commonly seen failure is the wrong fluid, this system uses ATF (dexron 3, iirc, it's stamped on the older caps.) PS fluid will break them.
Getting a bigger, or different pump is likely to cause issues with the steering box, or some other headache. Look into rebuilding what you have, there are rebuild parts available. If you are determined to upgrade "hydraulic ram assist".

Delivery man,, repartidor. Better translation would be "distribution block".

If ONE brake is locking up your issue can ONLY be with the TEE being plugged on ONE side or the tubing/slave cylinder (the side that is NOT locking up) or brake shoes on ONE side (either one side is grabby or the other side is not working).

Mine was bad when I bought my 91 in the winter. Flushed it with the old pump in place, then replaced it with a ~$30 rebuilt one from Advanced Auto and performed the factory bleeding procedure. No issues. Did you flush and blead IAW the FSM?
