Bleeding brakes

Hey guys I did the rear rotors/pads on my girlfriends 03 v8 4runner and after getting that done I figured I should prob bleed the brakes since its prob still the original fluid.

Anyway I have a hand vacume bleeder and I hook it up the the rear passenger bleeder screw, build up some vaccume and then crack the bleeder screw. Started pulling fluid out very slowly after pulling out a couple table spoons worth of fluid, I closed the bleeder screw, and then went under the hood and took a look at the master cylinder and of course THEN read the little warning statement saying its a high pressure brake system and to release pressure before servicing.. So I'm like wtf does it meen a high pressure system how is this different than any normal car. I stopped the proces of bleeding the brakes immediatly as this car was my ride home and took it on the road to bed the brakes in. They seem spongy (might just feel that way because I drive a sedan with really good brakes most of the time) but they deff had enough power to totally lock up the wheels at any speed. It seems like the front wheels are only locking up though.

Did I do something worng? I have built/restored a few classic cars and done motor swaps. I like to think I know cars pretty well but I dont work on new cars for a reason.. they're too damn complicated.

BRAKE − BRAKE FLUID (W/VSC)(From August, 2004)
BRAKE FLUID (W/VSC)(From August, 2004)
BLEEDING
NOTICE:
 Wash off brake fluid immediately if it comes into contact with a painted surface.
 If the brake pedal is depressed with the reservoir cap removed, then brake fluid will spatter.
HINT:
 If any work is done on the brake system or if air in the brake lines is suspected, bleed the air from the
system.
 When bleeding, keep the amount of the fluid between the Min. and Max. lines on the reservoir.
1. FILL RESERVOIR WITH BRAKE FLUID
Fluid: SAE J1703 or FMVSS NO. 116 DOT3
2. BLEED BRAKE BOOSTER W/ACCUMULATOR PUMP ASSY
HINT:
Perform this step only if the brake booster w/ accumulator pump assy is removed and/or installed.
(a) Turn the ignition switch off, depress the brake pedal 20 times or more, and release the pressure from
the accumulator.
(b) Fully depress the brake pedal 10 times.
(c) Turn the ignition switch to the ON position and start the brake booster pump.
(d) Make sure the pump operates for 8 to 14 seconds.
If the pump does not operate as specified, repeat steps (a) to (c) and recheck the operating time.



3. BLEED BRAKE LINE
(a) Front brake line
(1) Turn the ignition switch to the ON position and wait
until the pump motor has stopped.
(2) Connect the vinyl tube to the brake caliper.
(3) Depress the brake pedal several times, then loosen
the bleeder plug with the pedal held down.
(4) At the point when the fluid stops coming out, tighten
the bleeder plug, then release the brake pedal.
Torque: 11 NVm (112 kgfVcm, 8 ftVlbf)
(5) Repeat (3) and (4) until all the air in the fluid has
been bled out.
(6) Repeat the above procedures to bleed the other
brake line.
(b) Rear brake line
(1) Turn the ignition switch to the ON position and depress
the brake pedal.
(2) Connect the vinyl tube to the brake caliper.
(3) Loosen the bleeder plug and release air.
HINT:
Brake fluid is sent through the pump, so keep the brake pedal
depressed until the air is completely bled out.
