Silly brake bleeding question

[DJDV1]

Ok guys I have searched the forums for about an hour now and I have found that allot of the threads that are posted can be confusing and also have information not specifically meant for the model and year vehicle in question.

So here is my question:

How do I bleed the brakes on my 1997 4Runner 2wd Automatic with ABS?

I have read where you need a scanner tool to activate the solenoids??
Doesn't sound right....

Then I have read that one must bleed the brakes with the vehicle running.
Still Doesn't sound right....

I have always bled brakes by starting at the wheel cylinder furthest from the master cylinder:
RR
RL
FR
FL

NEVER PUMP THE PEDAL

JUST PRESS AND HOLD, then open the bleeder, wait a few seconds and close the bleeder letting your helper know to release the pedal

Repeat and repeat until finished.

Is this correct ?
Am I missing something?

Please let me know.


The reason for this question is because I tried using a mighty vac to bleed them myself after doing pads rotors, shoes and drums and my brake pedal is still soft.

Gonna have my neighbor help me tonight with bleeding them again.

Thanks for your help.

The order is correct , add bleeding the LSPV last.
You do want to pump the pedal slowly, and the person pumping must keep the pressure on while you open and close the bleed valve.

And if you have ABS it's a bit different.

I open bleeder and then have helper push pedal to the floor. Then I close the bleeder and have helper release the pedal. Pump the brake can make a few air bubbles into lots of tiny one that go everywhere. (A quote from my truck service manual) On your 97 I wouldn't worry about the abs. As long as it wasn't activated with the system open your good.

Thanks guys much appreciated!!

I did not have the vehicle running or the key switched to on when I tried it myself so ABS was not activated


I have ABS so I assuming LSPV is not applicable in my case?? [MENTION=1857]fourwd1[/MENTION]

What do you do if you have ABS?

I've done nothing different on my 96 and 97's.

I have a 98 with the same brake setup as you do and I've found it much easier and it flows a lot more fluid with the engine running. It's perfectly safe, just be aware of where the exhaust piping is (it's hot) and you'll be fine.

For 01-02 the FSM says it's required to have the vehicle on for bleeding, due to the pump being on and running.

99 with ABS, engine & key off, pump 3 times & hold down.

LSPV is the load sensing proportional valve, which increases rear braking when there's more weight in the back. I think the 3rd Gens have it.
Nothing to do with ABS.

All of them or just the newer ones like 01-02?

Most 3rd gens do NOT have a LSPV. I know mine does not ('99 w/ ABS). If I had to guess, I'd say only the non-ABS trucks had the LSPV for 3rd gens, at least in the US.
