Need help with my 96 camry LE. It has now about 97k. Three four month back I did a brake job. Right after that I could smell somthing burning from the front. Went back to the mechanic, he said some times new pad smells that way. It will be OK with time. So I had this smell going on. but Four days back I came back from a 5 hours drive I could smell the same burning smell but little stronger. I didn't drive the car for 3 days, when started yesterday it took three try to start. But today it does not even startl. I think battery and starters are OK. Light can be ON. It does not crank. It makes electrical relay tick tick sound.

Is this a normal problem? Need your help.

No guarantees, but it is probably your starter contacts:

Yes, it is a common problem

Thanks. Any Idea why the burning smell?

Unrelated - no idea. Check your brakes to make sure they are not binding against the rotor. They will cause big trouble if they are too tight to release the pressure on the rotor.
