I have a 1987 4Runner. While trying to bleed my brakes after a rear axle gear swap, I noticed the LSPV bleeder screw is broken off, so I can't bleed the LSPV. This is one of those with a solid hex head bolt and a separate bleeder nipple. Does anyone know if I can get this bleeder screw anywhere without buying a new LSPV? If I can, I'd drill out the broken one and replace it, but the dealership says they don't have a part number for just the screw. I assume it is (some thread?) metric hex screw with a conical tip like the other bleeder screws, but instead of having a hollow passageway thru it, it just opens a port to the bleeder nipple on the side.

If I can't find one, what do you think the most successful way to bleed my brakes without touching the LSPV is? Can I even fully bleed the system without being able to bleed the LSPV? I basically dumped all the fluid out of the rear when disconnecting the lines. Just kills me to pay $218 to the dealership for a new valve when all I need is the screw. Most trucks have the standard hollow bleeder screw too, so it's hard to find in the junkyard... Guess I could spend $120 for one on eBay, but still...

I recently went through replacing mine with a new OEM one sourced from the middle east. I took the old one apart and it was a bit gooey inside but probably would have been fine after cleaning. I think i kept all the old parts. If you want it, it’s yours for the cost of postage. I’ll have to check in the garage and find it Saturday.

That would be awesome if you can find it! Would be really nice to have good brakes here in Colorado in the winter

I took mine apart, and like Melrose, it was pretty full of old sludgy fluid. but it cleaned up well.
And your assumption about the bleeder screw is pretty accurate. Essentially just a bolt with a conical end. No hole. I think the revised LSPV has a single, more conventional bleeder.

I've got one up for grabs from a parted out '87 4 runner with the arm still attached
