What is a LSPV on a Toyota pickup?

The factory Toyota braking system still slows our Tacoma down just fine, even with the added weight of larger wheel/tires, suspension, rollcage, etc. But after installing the long travel rear suspension, we knew something had to be done about the stock Toyota LSPV (Load Sensing Proportioning Valve).

How does a Toyota brake proportioning valve work?

It is a spring-loaded component that activates when fluid pressure builds when you step on the brake pedal. Then, the valve’s plunger unseats and fluid rushes into the calibrated range. Once this happens, the spring gets compressed and the plunger blocks the fluid from passing through.

The load sensing valve (L.S.V.) serves the purpose of automatically adapting the brake pressure and therefore the brake force according to the load of the vehicle.

What happens when a proportioning valve goes bad?

A faulty brake proportioning valve could increase your vehicle’s braking distance, as it might reduce the pressure from the rear brakes too much.
