I know this has been covered but I can't find it in the archive.

The car:
1995 Integra GSR

What is the procedure for bleeding the ABS and when should it be done ie: before or after the system is bled?

I am not sure what years used this same unit but I do know is they have used several different ones between 1994 and 2001.

TIA

 

Hey, it's your lucky day. I happened to save this from the last time.

================================================== ===

Here is the procedure for ABS brake fluid replacement (from the Helms manual - for '94-'97 Integra):

1.) Remove the bleeder cap from the maintenance bleeder on the modulator unit.

2.) Attach the wrench to the maintenance bleeder.

3.) Connect a rubber tube of the appropriate diameter to the maintenance bleeder, and set the other end of the rubber tube in a suitable container.

4.) While holding the rubber tube with your hand, slowly loosen the maintenance bleeder 1/8 to 1/4 to collect the brake fluid in the container.

CAUTION: Do not loosen the maintenance bleeder too much. The high-pressure brake fluid can burst out.

5.) Tighten the maintenance bleeder.

6.) Start the engine and let it idle for a minute. Stop the engine.

7.) Check the brake fluid level in the reservoir. It should be below the MAX (upper) level line.

8.) Repeat the steps 4 through 7 to drain the rest of the brake fluid from the modulator unit.

9.) Remove the cap, and refill the reservoir to the MAX (upper) level with fresh brake fluid.

10.) Repeat steps 4 through 8 twice, and refill the reservoir to the MAX (upper) level with fresh brake fluid.

11.) Tighten the maintenance bleeder to the specified torque (8 lbf-ft).

12.) After replacement, start the engine and make sure that the ABS indicator light goes off.

================================================== ===

BTW, '98-'01 Integras do not need to bleed the ABS system since it doesn't have a seperate brake fluid reservoir for the ABS system.

 

Thanks bro. Do they say when this should be done? Before or after the system bleed or does it not matter?

 

It doesn't matter.

 

What about the '97 ITR System. I know that it is different from the '97 base system. Is this an independent one like 98+?

 

Yes, it is the same as the 98+ Type-R Integra ABS system.

 

So can't/doesn't need to be bled, right?

 

I read 2 stories..

1. All G3 Integras have THE SAME system.. (seperate ABS from main)

2. 98+ Have ABS system that "shares" with the main when activated

Which is true?????

 

All '97+ Type-R and all '98+ Integra ABS system do not need to be bleed. The reason why is because they do not have a seperate brake fluid reservior for the ABS system.

 

1. False.

2. True

 

This is a nice piece of information to keep in mind. Thanks Bret.

 

HRMmmmmm...interestin....thanx...

 

hey guys,
i know this is a pretty old post, but i had it bookmarked cuz i felt it was very helpful. anywho, i've got some problems with a spongy pedal, and i'm 99% sure its a MC problem, but i want to assure that remaining 1% and not spend $220 by covering all my bases. i've already bled my brakes a few times and checked for leaks to no avail. so my question is, do you think that bleeding the abs reservoir will help with my situation? and if so, i've got this little pump i use to bleed my brakes, so can i bypass steps 4 through 6 below by using the pump instead of starting my car over and over again? oh yeah, and i'm using ate super blue, but the abs reservoir still has the clearish OEM fluid in it, so if i bleed it, should i be seeing blue inside the abs reservoir?

TIA!

I wish my ABS still worked... at least I don't have to worry about bleeding it. Nice post.

 

I don't think that bleeding the ABS will help with a spongy pedal. But it couldn't hurt to try, especially if the ABS hasn't been bled in awhile.


You will not be able to use the pump to bleed the ABS system. The reason why, is because the ABS system is under pressure. When you bleed the ABS system the pressure in the ABS system is released. So you will need to start the car between bleedings to re-pressurize the system.



Yes, you will need to continue bleeding the ABS system until the brake fluid turns from clear to blue. ATE Super Blue (and Gold) is great for bleeding the brake system, because it is easy to see when the 'old' fluid has been replaced by the new.

 

hey everyone
i tried this aforementioned ABS bleed procedure, and it resulted in draining all the brake fluid from the ABS reservoir. the reservoir would not fill up. so i called an acura service department and they told me that they have a special machine that cycles the brake fluid by essentially engaging the ABS while the car is still. is there a way to repressurize the ABS system without going to the dealer and paying an assload for something that essentially seems simple? TIA

anyone? bret?

 

I have never had a problem getting the ABS reservior to fill up.

Did you complete drain the ABS system and then try to fill the reservior???

I always relieve the pressure in the ABS system and then restart the car to pressurize the system. Then I shut the car off and refill the reservior to the MAX fill mark and re-bleed the ABS.

HTH

 

man, that sure does sound like you would be starting and stopping the car ALOT of times.

 

I did not completely drain the reservoir. i did it bit by bit, then repressurized the system after draining a bit of fluid. i kept starting and shutting off the car, and i thought the abs reservoir was refilling itself, but i guess the fluid in there had stained the side of the reservoir so it looked like it was full. i came to realize this after there was no more fluid coming out and my abs light was coming on.

should i just try to keep bleeding the system even though there is no more fluid left and try to get the reservoir to fill itself?

TIA
