ABS Failing Options

[barterj]

I am away at college and don't drive my car that often anymore . I noticed that when I drove it during thanksgiving break that the ABS failed to work when i had to stop quickly, luckily I didn't rearend the car in front of me. The Front Right Tire locked up, and then after that i noticed that when I normally apply my breaks that the Front Right Wheel seems to have more breaking pressure than the Front Left Wheel. I have gone through the electrical part of the system and can't find the problem. The ABS light is NOT on. My first assumption was the the ABS computer has failed, then i thought that the ABS module had died but either of those would make the ABS light come on. Also the ABS solenoids are fine and working. I plan on having the issue diagnosed Toyota. Does anyone know what could possibly be the problem?

thanks for all the help, im going to be driving the car again this coming weekend and im going to see if there is anything else that might help me figure out the issue. I also have to replace a cv boot and clutch so I will look at the calipers at the same time.
