Maybe you need an abs scan tool to properly bleed the abs system? I am not sure if you have to do that with honda abs. I had a civic with no abs. I bled the brakes a couple of times and still had a soft pedal. It wasn’t until I adjusted the parking brake cable that I got good firm brakes. Is your parking brake cable adjusted properly?
Since you opened the system before the abs module, you may have air trapped in there, and might need a Honda scan tool to bleed the system correctly, but I’m not certain. I’m not sure how the parking brake cable would have any effect on your spongy brake pedal. I’ll refer your post to Eric who is obviously the Honda guru around here.
as far as i know the parking cable is a cable, doesnt usually have anything to do with brake fluid. usually if the abs is acting up it would try to push ur foot off the peddle at random or not work at all, is your abs light on? my best guess is air in the lines you can use a piece of clear hose attached to the bleeder screw to see when the air is completly out of the line.
no my abs light is not on. I don’t lose any brake fluid in my master cylinder. Thanks for the reply..mze
try bleeding the brakes with two people. one pumping and holding the brake pedal. the other opening the bleed screw.C8-)
Possible seal leaking. I’d check the master & slave cylinder seals in the master cylinder, and the piston seals in the calipers as well. Since you took the master cylinder off you should also have removed the power brake booster and checked the seals for leaks. You can do this by manually moving the push rod back and forth and looking at the fore and aft seals around the push rod.
Make sure your front caliper pins/slides are not seized. I had a soft brake pedal kick my ass with this problem before.
I am assuming the soft brake pedal existed before the recent repairs? And this is why you did them? If this is a problem that started after your repairs then disregard my suggestion.I am curious too if the problem was present before you making any type of repairs?
Also stated above, you may or may not need an ABS scan tool to bleed the system.
After doing extensive research on the soft brakes issue, I notice Honda and acura have also soft brakes with some their cars,. One of the problems was abs modulator. It could be defective or air in the abs system which needs the dealer to bleed the abs system…
I made a video about this very thing, now be sure that you’ve covered all the other bases first and make sure you don’t have air in the system, this really does work BTW. I will also say that the friction material that you use has a lot to do with it too so if you didn’t use OE pads I would recommend Akebono as a close second, and make sure you follow the brake servicing recommendations in these first videos for best results.
