brakes/bleeding

[doubleA]

hi all

i am planning on changing my rotors/pads soon.

I found through searching that bleeding the brakes requires a computer hookup? I ask because if I need new calipers will I be able to bleed the brakes?

The dealer may use Toyota's tech stream to bleed, but you can do it just fine w/o it. That being said, several members have had issues bleeding these brakes. Leave key in on position. Pump will bleed rears w/o pushing on brake pedal (!). Fronts get bled the old fashioned way. Do not press too hard on the brake pedal when bleeding, as you can damage the internal master cylinder components. Lots of advise on whether to start bleeding at farthest cylinder from master, or whether you should follow Toyota's sequence for bleeding. If you let the master run low or dry while bleeding, you will end up having to tow to dealer so the tech stream software can open and close the solenoid to get all the air out. Be particularly careful with the fluid levels when cracking the rear bleeders open with key on.
Best of luck!

Seriously? Top off master cylinder, put key in on position, and the rears will be bled automatically? Never heard of this before.

On position means start the car?

that would only be needed if you somehow get air into the MC/ABS unit. if no air, you don't need a scan tool.


also, to prevent issues, when compressing the pistons into the calipers, crack the bleeder open, and let then excess fluid out there. don't force it back up the line, into the MC/ABS.

I just did it on mine, old school 2 people brake bleeding. Pressed pistons back with small pry bars, screw drivers. Nothing special. No scan tool.
