Need some help with my brother...?

My brother is... interesting... he is the "i dont care what happens to me as longs as equal or worse happens to you" type person.... not in ever sense... but he is also a snitch and tattle-tailor, and a non-remorseful lire(lies allot without feeling bad) (no exaggeration). It seems that every time he comes with me and my friends are there, he makes up, or blow a story up to the point where i will get into trouble. Just today i got grounded for something that never happened. I have tried to get him to stay away by asking nicely, but he still follows, or by force, the he tells and i get in trouble. And as of today, he hates me because my friends apparently hate him, though they say the don't and they did nothing bad to him... i was there too. he has been doing this for 5 years and i am sick of it. i NEED him to stop. every one has said "Beat him up" but i cant because i will get KILLED by my parents... it also doesn't help because his pain tolerance is that of a teaspoon. My parents only believe him... how do i make it stop? he has got me in trouble because i didn't barrow him a game. he said i threatened to kill him... and i DID not. how do i get this to stop.
