Load Sensing Proportioning (LSP) and Bypass Valve (BV) leaking

One of my sons' brought his 2003 Tacoma PreRunner TRD Off Road to my house because he was having to put brake fluid in the master cylinder reservoir every day.
The Load Sensing Proportioning (LSP) and Bypass Valve (BV) was dripping brake fluid on the ground. The dust boot was also torn.
I looked up the part and the least expensive was $185 next day shipping from Amazon. Looks like a Toyota only part.
Yes there were aftermarket self adjustable parts available to order on line but I decided to pass.
After googling results of this problem I noticed a couple of persons stated that they removed the unit, cleaned then re-installed with no leaks.
That is what I did and the leak problem went away.
Once the unit was removed from the truck I removed the rubber dust boot, the snap ring, plastic rod centering piece and rubber gasket. I tried to remove the nut holding the piston and spring but it wouldn't budge and I didn't have an impact socket that fit.
I cleaned everything that looked dirty then put back together. It took a brass brush to clean the crud off the metal parts.
The torn dust boot was sprayed with several coats of Plasti-Dip as I didn't have any thing else.
A thorough brake bleeding was performed with my old Motive power flusher using three quarts of Valvoline Dot 3/4.
The end results were no more leak and normal braking.
Just an FYI for anyone else with this problem. Hope this helps someone save $$$.

 

Apparently there is a OEM rubber boots kit for the LSPV. So when there is a torn boot or a leak, you can buy these instead of a whole new LSPV unit

part number:
04477 BUSH & BOOT KIT, LOAD SENSING SPRING
04477-60010 (01/1995 - 08/2000)
04477-60040 (09/2000 - 08/2004)

 

yeah, definitely cheaper!

 

I don't remember

It's been a while since I touched my LSPV and I can't go check on the truck since I am out of town for the week :/
