ABS Brake Flush
I was wondering if anyone has had experience flushing/bleeding the 4th Gen, or even 5th Gen, Accords. If so, could you tell me the proper procedure to do so? I understand there's a timing issue with the ABS system, so any help would be appreciated. Also, has anyone done a brake master cylinder and/or proportioning valve upgrades on their cars? What works well for you? Having just swapped for wagon front brakes, I'm wanting to compliment the larger calipers.

From what I understand the Wagon's Master Cylinder and Sedan/Coupe EX Master Cylinder are the same. You already have the correct proportioning valve for the front wheels in your ABS solonoid unit, So not only can you not change it but it would make no sense to do so.
As for bleeding the brakes. The best source for you to check with would be a service manual. The Brake fluid in the ABS solonoid assembly and pump are completely seperate from the fluid in the brake system. Bleeding it should be absolutely the same as bleeding any normal non-ABS car.
The brake fluid in the ABS solonoid assembly and pump is just for the valves in the ABS solonoid so it can acctuate them when it's necessary. You shoul never have to bleed that system or open it for that fact of the matter. It's a completely sealed off system.
But if you want to flush the brakes system I would consult the manual before begining. It should not be an issue because or my experiance in ABS brake systems and their design but maybe there is something special I don't know about with the 4th gen Accord. It's better safe then sorry. I always consult the Service manuals before begining work on a vehicle I'm not familiar with.
Good Luck

Our '98 Accord doesn't have a separate system. When you bleed the main brakes, it flows thru the ABS system. So you ARE bleeding the ABS while you bleed the main brakes.
I don't know which system the earlier Accords are similar to, but I wouldn't say that it's not needed.

Um.... If you have to ask, I hope you're not going to bleed your own brakes.
I don't have a 5th gen, & our '98 is auto anyway... But it's REALLY obvious whether it has separate reservoirs. Either the clutch master has it's own reservoir, or it has a small hose going to the brake reservoir. Take a look.
I imagine 2 liters would be enough.

5th gens have a separate reservoir for the ABS...you can use Super Blue in there.
Its a lil tricky to bleed from what I have read and unless you have a power set up you may not get all the fluid (like an AT drain and fill), but will have to drive the car, engage the ABS and flush again several times to properly flush it.
Warning, if you open the valve while the engine is running the fluid will start to spout like a geyser...
