Default Bleeding Brake Sequence On LS430?

I need to flush/bleed my brakes, and usually the order you bleed brakes goes from the furthest brake caliper from the master cylinder to the closest. So most cars would be:

1) Passenger Rear
2) Driver Rear
3) Passenger Front
4) Driver Front

My understanding though is the earlier LS400 model, it's a different sequence

Does anyone know the proper order for the LS430?

Thanks, I only have bits and pieces of the factory manual.

Digging through older threads the sequence is posted as you have.

In addition there was an old link that was broken but StopTech still has the white pages up. Give this a read as well:

I don't have my manual handy but I bled the brakes this summer and used the Honda procedure.

Hondas categorically have pretty weak braking systems. They stop alright, but their components are kinda cheap - master cylinder, abs, disks, calipers, ect.

And Honda mechanics swear the best way to bleed the brakes is to start with the driver's front wheel. The reasoning is that the junk/old fluid will get out of the system quickest, rather than pumping it all the way to the right rear wheel.

The procedure I used was like this:

0) Driver's front
1) Passenger Rear
2) Driver Rear
3) Passenger Front

It's fine to do it either way and if your fluid is in alright condition it probably doesn't matter which sequence you take.

That's an interesting strategy, I hadn't thought of that. I had just always gone by the old way of furthest moving in to get all the air out.

My main issue though is flushing the brakes, I don't have a spongy pedal. I did a test on the fluid and it looks bad. It might make more sense to get the nasty fluid out rather than pulling it through the whole system. Usually I drain the reservoir first, top it off with fresh fluid, and then bleed until I get fresh fluid coming out the bleeder screws.
