Walkaround 4Runner Brake System Upgrade and LSPV Delete

DISCLAIMER: I think it's obvious brakes are the most important system on your car. Please make sure all work is done to the standards that a dealership mechanic would conform to. If you are unable, please do not attempt brake work. Secondly, do not delete the LSPV. There are mixed opinions on this topic but I stand behind mine. The LSPV system is a constantly variable proportioning valve. No manual proportioning valve can claim to work as well. Also, when I removed the LSPV the rear brakes never worked as well. For reasons unknown, the automatic brake shoe adjustment system ceased to work after this mod. I dealt with this for less than a year before installing a functioning LSPV from the junkyard.

My LSPV has been leaking since I purchased the Runner. I decided to upgrade the whole brake system at once. V6 4Runner calipers and MC, Land Cruiser wheel cylinders, LCE rotors, stainless braided brake lines, manual proportioning valve, and a few other small odds and ends. These are easy but factory looking clean retrofit is not. See how I did it.

If you remove the LSPV then you must cap off the third line from the junction at the front brakes and install a proportioning valve for the rear brakes. I will also add this: I didn't leave it like this for even a year. Removing the LSPV caused the rear brakes to suck and the auto adjustment for the drums stopped working correctly. I get fed up with it and installed a working LSPV from the junkyard. I recommend refurbishing your OEM system rather than doing what I did with the LSPV.

Im in England, thanks loads for your fantastic information! your vehicle is so clean underneath! Mine has thick corrosion is on everything, and every fastener is a major pain in the ass to undo!

[timdiebert]

Great video! Thank you for being so detailed & clear on things.

From what I've read from other people who did this swap, the reason this didn't work out for you is because you have drums in the rear. Seems full disc truck owners are happy with the lspv delete.

Thank you for explaining which lines go to what, I am installing a wilwood PV in stock location, but wanted to know what line went to the front brake.

How do you adjust the proportions valve
Di you install on the rear breake line ..

You sir have just saved me a lot of time and anger lol

[jacobbaugher]

Looks like it’s the top, but want to verify it’s the top line running along the firewall that is cut to fit the manual valve correct?

[Jay]

Looks great. Something I will be doing since the lspv rotted away

[rolandvzable]

If possible could you post a link to the flare fittings? I'm doing this to a 98 Tacoma and my set up is bit as handy as

[jeffguia]

Question for the calipers what year or it doesn’t matter? Thx

[ottos]

Did the system work normally after you took out the other line? I have Toyota landgruiser LJ70. I read from a offroad forum that if you take the secondary line out entirely the brakes dont work normanny afther that. Great video by the way.

[reboureyn]

I got some EBC pads and rotors and they were like yours, drilled and slotted. Except my drilled holes are not drilled all the way throught. I looked this up and it says rotors that have holes drilled all the way through have a higher chance or warping. every hear this?

[jeffgood]

But what about that that line u have to block off it goes up front to the power steering or something I imagine and wraps back out to the rear self leveler so just take that line or lines off that system and block the wholes 5/16 pulgs

[pconstante]

You don’t explain how you got rid of the p valve how you rerouted the new lines

[TheAlexManVideos]

Yep. It's still not as good as a modern Honda Accord or something but it's better than it used to be.

[TheBeastGerman]

Did you make the bracket for proportioning valve or buy it

[creativesymon]

I won't be removing my LSPV, just renew it, *but how did you find your other upgrades worked?* The better calipers and drum cylinder? I'm upgrading my 3L diesel to a 4L V8 and the brakes are something that were never too good. So double HP and torque means they need major attention...when I get to them.

Notice a increase in stopping power?

Your rotors are on backwards. The veins should be pointed towards the back.
