Brake and ABS bleeding. learned something today

BLCKFLSH · Jul 13, 2011

I read on another forum that the bleeding sequence has changed, for newer Accords (98 and up, from what I read). Also there is no need to bleed the ABS, supposedly because the fluid will go through the modulator during normal calliper bleeding. I looked up the sequence in the 03-05 Accord service manual, and sure enough it says nothing about bleeding the ABS. I scanned the page. This is the new sequence

This was the old sequence

I doubt it really matters a whole lot, which rear wheel is done first, but I thought it was useful information. Also nice to know I don't have to worry about bleeding the ABS.

I read this on v6p about bleeding the abs:

Before u look into a master cylinders get a 14mm and 10mm flare nut wrench and bleed your ABS modulator just like u would bleed the brakes. Have your Buddie hold the pedal down and crack open the two bolts on the side of the ABS modulator one at a time I did 5 pumps on each one or until there is no air. Then move on to the 4 brake lines on top of the modulator do these the same way one by one 5 times each. Then bleed the calipers I did the wheel closest to the ABS modulator so Passenger front, Driver Side front, Passenger rear, Driver Side rear. I had the same problem flushed the system 3 times then i called my uncle who is a Master Tech at Honda and this is how he told me to do it and it worked.

Make sure to keep an eye on the fluid. Constantly check it I got real low a few times but got lucky. Once u get an air pocket out of the lines the fluid will drastically drop.

Good luck

I'm curious to know if it's actually necessary. I've only bled the calipers.

You really should not need to bleed ABS unit unless you replaced something in brake system upstream .
I used to work on many vehicles that had bleed nipples at the ABS unit , on normal fluid replace/bleed normally it never needed , maybe if you let air get into system its probably faster to bleed the ABS then wheels ,then to bleed it out only at wheels .
If out of blue you need to bleed system I would look closely at each component to see what might be going bad .

FWIW my gen8 accord has no bleeds at ABS unit .

Here is a quote from the expert.
"Beginning in 1998, Accord ABS no longer has a separate fluid reservoir, and no longer has a separate bleeding sequence. Bleeding the main brake system pushes fluid through the newer ABS system and no additional bleeding is required. Bleeding order for the newer cars is LF-RF-RR-LR."

Here is the link, if anyone wants to read it. It has directions for bleeding the ABS systems for 97 and older Accords.

your original post is correct info on order and procedure .

Oldie but goodie.

Thanks, Blckflsh. Couldn't remember the sequence and was wondering how I could bleed the ABS. Just threw new rotors on the fronts and am planning to bleed, soon as I can pick up some Valvoline Dot 3-4. I use the hose submerged in fluid, one-man method.

I'm going to bleed once a year now.

I lube slide pins every year. I crack the bleed nipple while compressing the caliper piston with a C clamp. That gets rid of the fluid in the caliper. It goes through extreme temp excursions and you don't want to push that back up into the system. Other than that, I flush every few years.

This is my latest brake lube...ceramic. Don't know how it will perform but supposedly turns into a dry film. "Up to 3000 *F working temp"....
