    Verify mo rin kung kailan ka last time nag pa bleed and renewal ng fresh brake fluid? Napa check mo na rin ba kung may leaks?

    If you are sure na walang leaks sa brake master, and inside the cabin sa brake pedal.

    pa-bleed mo brake system mo, might be trapped air bubbles kaya ganyan brakes mo.
    at the same time, check brake pads and pacleaning ka nadin ng brake drum shoes.

    If you had these done and medyo lumulusot padin yung preno,
    might be palitin na yung piston ng brake master mo, pwedeng i-repair kit yan
    or kung medyo na-ukit na yung cylinder, brand new brakemaster assembly na ang solution dyan.
    pero either way, if ako ang may-ari ng kotse, palit nalang ako ng OEM brake master assembly.

    maging top priority mo yang preno sir.

    Sir hindi normal yang ganyan... better have it checked muna for leaks and start from there... we can't say directly what's wrong based sa ganyan lang na description

    Thanks

    Sir just to verify lang, nag kikick-in ba yung ABS pag dumaan kayo sa lubak and lumalalim yung preno? I'm also a Mazda 3 owner po (V - 2005 model) kasi and I've ran into similar situations with my unit. Just to share my story (sorry mods kung nobela) Immediately after the ABS operates, either because of potholes or sudden braking, lumulubog yung preno. It eventually goes back to normal however, when I pump the brakes or just by continued use nung auto. My online research came up with two most probable culprits. Either the brake master failing or the ABS pump having issues. Then 3 months ago, nangyari uli yung issue but this time, hindi na bumalik sa normal yung preno. Kailangang sagad to the floor na talaga yung apak para mag-full stop yung auto. I was expecting the worst but what I initially did was to follow what most of the auto-gurus here always suggest... start with the simplest and cheapest possible solution first, which in my case was to do a total system flush/refill of the brake fluid. Lo and behold, it worked! Balik agad yung normal feel at operation ng brake nung auto. To this day, I have not experienced the same issue kahit na nadadaan pa ako sa lubak and even after mag operate ng ABS. Hope this is also the same case with your unit.
