Rear end - tundra

02 toyota tundra- pressure relief valve on the tundra rear end plugs up causing the fluid to seep into right rear brake drum,this in turn causes the shoes to grab and lock at slow speeds. Has anyone ever heard of this? I have had this repaired twice, will this continue?

If the truck isn’t used to launch boats where the rear axle is submerged in water, you could remove the check valve and then adapt a rubber hose with enough slack in it so it can be secured somewhere under the bed.


yep do as tester said,but only run it the whole way up under the hood (to the highest point)in case you do get a boat down the road,and forget.
or cruise through a creek in flood waters,keep it high.
