Does anyone know what the name of the part that is located behind the passenger side wheel which the two front brake lines go into and the one from the other rear wheel? Also is this part replacable and is it universal or specific for a 4 runner?

 

the caliper?

 

Need more info, what year 4runner, front wheel or rear, and pics would help greatly

 

LSPV, load sensing proportioning valve. There's a rod connecting it to the rear axle right? It adjusts front to rear braking proportion depending on how much weight you have in the back.

 

rear proptiong valve (sp?)

 

Are you talking about a combo valve? And what eric said.

 

Is that valve something that is easy to replace becuase many stores do not have it? If so does anyone know where I can order it from?
