Hi guys, trying to diagnose my Dads '97 Accord with ABS. I've removed all 4 ABS sensors cleaned and replaced them. I've bled the front brakes, and will be doing the rear once we've got replacement bleed screws.

Is there a secret to bleeding the actual ABS unit? Is ti possible? The ABS light still comes on when youve been driving for a while and stomp on the brakes. It pulses a bit as well under light load. any thoughts?

Thanks for the help.

Yes it is possible to bleed the pump/accumulator unit, there is a nipple fitting on it you can attach a tube to it and catch the old brake fluid into an old oil bottle.
You'll need a really tiny funnel to keep the ABS reservoir topped off.
Don't fully open the bleed screw [HIGH PRESSURE]
Turn the key on to repressurize the pump unit, between draining/bleeding.
Brake pedal pulsing under a light pressure is probably not the ABS.
I would think warped rotors the most likely cause.

Remember brake fluid will eat paint, clean up any spills with brake cleaner spray ASAP

 

Thanks for the reply! I'll give that a shot when I see the folks on the weekend.

Much appreciated.

 

It would be nice to know the code that gets set when the light comes on, I will say that the problem fixes itself so it self terminates the light, I would guess that it is pressure related, not WSS related.

 

i have a 97 accord 2dr coupe 5speed..
wen i pull off my abs light goes on and stays on and if off wen i brake it will pulsate den light will come on to help brake.
Is there sumthing i should check to find out wat it might be.
