no rear brakes?

everytime i pull up to my garage i notice that my front wheels lock up quick and i kind of just slide to a stop.

same thing in the snow this year. when i get on the brakes the fronts lock up and i just slide towards the curb.

where did the rear brakes go????

i know they are good. i replaced them only months ago!!!!

is there some kind of brake equalizer that went south???

there is a LSPV, if that goes bad then your rear brakes will not work. that is what is wrong with mine

if you want to search on here it is called a load sensing portioning valve or a LSP Valve

I would adjust your "adjusting star wheel" in the brake drums themselves so that the shoes are almost contacting the drum. This can also be done by going in a parking lot, driving in reverse, then applying the brakes a few times.

Hey Rons85..

mines leaked when it went out.
