I Change The Brakes Butthey Dont Wanna Grab Like New Brakes They Stillworklike Old Brakes!! Help Asap Please!!

I think you would get a few more responses if you include some basic information as to type of brake. And no offence here but using a space between words would be helpful.

Are you talking about disk brakes or drum brakes. Front brakes or rear brakes or did you change all four. Did you note any fluid leaks prior to doing the brake replacement or any leakage after replacement. Did you have the drums or rotors turned. Are you sure you used the right replacement parts. Did change the brake fluid or bleed off any brake fluid? Do you have a how to manual to reference to make sure you put the brakes back together properly?
