i just got the revo center diff and rear brake kit and installed it. but my question is, does any one who has the rear brake kit, can you get the rear wheels to lock up or get close to locking up?

I have the brake caliper screws on nice and tight but not tight enough to bind. when i push on the brakes by finger all the way the brake linkage just start to bend it it still doesnt lock up.

so does anyone else get theirs to lock up or close to locking up?

i know I know you dont want them to lock up because it will ruin our diffs, but im just saying, cause it seems like the brakes are weak
