All 74 through 78 Newport, New Yorker, Imperial cars had front disk and 74-75 Imperial had rear disk as well. I own three of these cars and I've not had any major problems with them. I've not heard of anyone else having trouble outside the usual stuff that can be expected of disk brakes. ----- Original Message ----- From: "Kenneth Napper" <I440toyou@xxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Sent: Tuesday, February 10, 2004 1:51 PM Subject: Re: IML: Imperial Disc Brakes I under stand that,disc brakes were not big till what 1977?The two big problems with four drums is over heating and locking up,new brake systems still lock up.To over heat Imperial brakes witch are the widest and longest any company made is very very hard,I am more concerned about the 2inch by1inch brakes on new cars.I own a great 1967 crawn coup.When the brakes changed to ceramic metalic material all pads got better ,so enjoy the best ride of any car made,worry about the person near you.
