Really unenjoyable brakes. Help :( (ALB?)

I know what it is, but there are two completely separate reservoirs for brake fluid, one for the brakes themselves and one for the ALB system...

Are Ludes not the same?

2nd gens are, I think all the early systems had 2 reservoirs but I may be wrong.

And like Merc says, the 2 systems work in conjunction so both need to be bled properly to function correctly.

That said when I fitted braided hoses on my Accord I somehow got away with only bleeding the main hydraulic system

Ahh didn't know this, thanks! Was just in a rush to try to sort it out with no internet this evening. Something else to get on with tomorrow then

The 2 systems comment though, if the reservoirs are separate and the ALB is now disconnected then it shouldn't affect the brakes. Just we now have no ALB. Which doesn't matter as it never worked anyway. Surely it shouldn't interact with the brakes if it's a separate reservoir and is now disconnected right? My mint one doesn't have it at all thank god.

if the 2 systems were separate why would it be an alb system it has to be connected to the braking system or you would have to have to sets of calipers

Have you got the Accord service manual?? I reckon it'd be worth comparing it to what's in the bay of your car. I just glanced it it to refresh my memory and the diagram says that the main system is plumbed in to the modulator - are you saying that your car has had the 2 systems separated and the main system has had new hard lines made up going to a proportioning valve or something? I have seen this on a couple of ALB cars which had borked ALB, from speaking to the Honda techs at my old dealership it sounded like their preferred solution to a Faulty ALB system

Obviously the systems themselves are connected. I think we may have crossed wires here? Everything I've been led to believe off the 3geez forum though says the fluid for each system is totally separate. So bleeding the connected brakes fluid, but not the disconnected ALB fluid, shouldn't affect the brakes themselves?

Maybe it's completely the wrong information though, this is the internet after all

Honda information on the ALB for the 3G Accord says that there is a 'fail safe' relay connected (which is definitely there in the fuse box) so that if the ALB itself fails the braking capacity is not affected...?

What I'm trying to say (I think?) is that yes, both systems need to be bled correctly to both work correctly, obviously. But if one is no longer connected, and the connected one is bled correctly, then the connected one will still work correctly, and the disconnected one will be irrelevant to the correct functioning of the connected one? Does that even make sense? I'm so tired and that was a lot of 'connect' or 'correct'

Downloading a service manual now, it's taking a while though. Looks like we've got a long night of reading ahead, after 2 hours sleep last night too.

I'd just like to apologise if anybody's brain exploded after trying to read that sentence

I am literally so tired I clearly can't even put together a coherent sentence anymore. I guess I should go to sleep and maybe try to rewrite my reply in the morning when I have a connected, correctly rested, functioning brain. Sorry

yeah when they say fail they mean electrically fail like a dodgy sensor or ecu the calipers will only have one fluid system which means the fluid from one system will have to mix with the other.
have a look at the caliper and see how many brake lines you have going to it?

The lines of the ALB system have to be connected to the lines of the brake system though right? So if there's air in the ALB system (due to it not being bled properly) there's air in the brake system.
