some people may say different but i always start from the wheel furthest from the master cylinder and work my way closer, so the order would be rear passenger, rear driver, front passenger, front driver.
what you do is take off the wheel and on the caliper there will be a bleeder screw, usually with a lil plastic cap over top of it. unscrew it a little bit (not all the way out) have some one sit in the drivers seat to press the brakes.
1. open screw
2. press brake pedal and HOLD
3. tighten screw
4. let off of brake pedal
5. open screw
6. press brake pedal and HOLD
7. close screw
and so on and so forth until you see fluid squirt out. do this for ever wheel in the order and wah lah, you bled your brakes.
