i was told that when you upgrade a erst to cossy brakes that the back end locks up easily. then i read somewhere that if you remove the load sensing valve it does away with this problem is this true. im doing a underside resto so i need to no so can run new brake pipes or get the valves cleaned up

 

cossie front or rears? leave the load valves imo, unless your fitting a bias valve

 

cossie rears is it true about the locking up tho what way do you get round that

 

you can run 4x4 rears as the piston is bigger it will not lock up.
its becuase on a smaller piston like a cossie 2wd the fluid will push the piston much quicker locking the backs first while the fronts are still trying to get fluid to the calipers.
or fit a brake bias valve.
