Question: The whole basis of the film is that Max is suddenly aware of hidden evidence that impacted his sentencing. However, his lawyer claims he wouldn't have known and hurried the case to keep it hidden. The question remains: how did Max find out about the evidence while in prison?
Question: So how exactly did Max Cady slip past Kersec's security system and get into the house? Did he kill the maid outside and then just walk in disguised as her?
Answer: He snuck in during the day and hid, before Kersec's teddy bear security system was set up. Sam Bowden realises this when he wakes from a nightmare. Its how he was able to poison the dog which hadnt been let outside. Max Cady killed the maid in the pantry with the same piano wire he later attacks Kersec with.
Answer: Kersec suspected that Cady might attempt to break into the Bowden house if he thought it was empty. His plan was for Cady to break in and then be shot dead as an intruder. He likely lessened the security to allow Cady to break in. Cady killed and then impersonated the housekeeper to get in.
I like your answer but I'm a little confused by the "lessened the security" part. If I'm not mistaken, every possible point of entry into the house at least from the ground floor was connected to the bear via the fishing line, so Kersec would know if a point of entry was disturbed by the bear moving. Where would Kersec lessen the security from that standpoint, especially since his setup was supposed to be foolproof?
Kersec wanted Cady to be able to break in so that there would be a plausible reason to shoot him dead. The idea is to make it look like his death was a result of self defense. I'm only speculating that Kersec made it easier for Cady to break in into the house. Being as it was his security system, he would know how to make it possible for Cady to get in.
Answer: As I remember it, Sam Bowden, Max's lawyer, knew his client was a rapist. He did not want Max to go free, so he buried the evidence that could have exonerated him. At that time, Max was illiterate, and Bowden assumed he'd never know about the hidden information. While in prison, Max, who was actually highly intelligent, learned how to read and also studied law. He later mounted his own unsuccessful appeals, which presumably gave him access to all previous evidence.
