    here is my story...

    i was driving the other day and all of a sudden my brake pedal went soft. so i decide to pull over to a gas station and checked if i had any brake fluid in the reservoir...it was empty!!! i then i fill it up to the max level...and still my brakes were spongy. when i get home...i check the reservoir...it was till full. so i figured i needed to bleed my brake system and so i did. STILL SPONGY!!! what seems to be the problem? should i change my brake master kit? or could it just be my brake lines? thanks in advance...

    hindi ba parang may mas malalang problem sir ang brakes mu. the brake fluid canister can't go empty without a major problem. in the gasoline station, did you just top up your brake fluid or did you check for problems?

    yes i just filled it up and never checked for problems...i figured it was just empty...cause it happened to me before. BTW, when i brake, my car veers to the right...its seems so that the brake on the left is not working...also, when i bled my brakes...the left brake had alot of air in it...

    There is air in your brake lines.

    You will need to have to bleed all the air out of your entire brake system before the spongy feeling disappears.

    I think you have a leak in one of your brake lines.

    If the problem keeps coming back even though you've bled the system time and time again, you should probably have your brake lines looked at. Unless you take care of the leak, air will keep getting into your brake fluid and you will still get spongy pedal feel.

    Check your underchassis for areas where paint has been stripped or melted clean off. That's where your leak probably is.

    i thought of that as well...i checked under the car for leaks but i found nothing...maybe i can just bring it to a shop...how much do you think they will charge for a fix if a leaky line is the problem?

    try checking the contct between the master ccylinder and the brake booster. the m/c might need to be reconditioned. there might be an internal leak too between the primary piston and the secondary pisto.
    is your brake system diagonal split or front/rear split? is it anti lock brake system?

    nung pinacheck ko ung brakes several years ago, i found out that only one side was working. It seemed that only one of the rubber thingies inside the cylinder was getting pushed forward when i stepped on the brakes, ung isa naiiwan.

    Apparently We ended up having the master cylinder replaced and a new repair kit installed. We also found a leak in one of the rear tires(forgot what that thingy attached to the drum brakes was called)

    I'm assuming it's diagonally split as it's a Honda.

    Di ba ang mga oto may dalawang diagonal connection naman ang brake circuit so that if 1 circuit fails may naiiwan pang isa.

    since the reservoir was empty, there is a great possibility that you have a leak somewhere in the system,

    find a competitive shop to get it diagnosed properly to immediately put the car back to safe side.
