I am going to attempt a break job for a friend on his 98 Concorde lxi and I was wondering if there is anything inherently difficult about this car's break system. His front rotors are warped and may need to be replaced. Is it particulary difficult to remove the rotors (front and rear) so I can get them turned (grinded)??? Is there anything else that I may need to know before attempting this. I've done plenty of break jobs, but not on this make or model. Thanks for any input.
