Ok, I have about 80,000 on the FJ so far and it's getting time to change the brake pads. I've always done this on my Tacoma and other vehicles and it's a fairly simple process. However, I recently bought a repair manual CD and it says to drain the brake fluid before doing the pads (???). Normally, I just take off the caliper, hang it from the wheel with an old coat hanger, change the pads, and reassemble. Does anyone know if there is some pressing reason to drain the brake fluid to change the pads on the FJ that I don't know about??

Thanks in advance for your response.
