Toyota Vios 2019 stiff brake pedal even after engine start

[InYourDrimz]

Hello po, inquire lang po ako sa mga experts rito., bale yung vios, matigas yung preno kahit naka start na yung engine (after 8hrs+ na naka park, dala ko sa trabaho) then ayaw mag shift ng gear, na gagalaw naman yung shift knob at makikita sa OBD na nag shift yung gear pero pag i gagas na, pa atras lang arangkada, tapos tinry ko i restart yung engine, ayun bumalik na sa normal yung brake at bumalik narin sa normal yung pag shift ng gear, 2nd time na nangyari, yung una nung malakas yung ulan pero umayos naman kahit hindi nirestart yung engine., ano po sa tingin nyo problem? Nakaka kaba lang baka bigla magloko sa daan, plan narin namin i pa check sa kasa pero baka hindi rin masyado i check since hindi naman madalas mangyari. salamat po sa mga sasagot


PS: automatic po transmission

Dalhin mo sa Toyota yan kasi under warranty pa naman ang unit mo. Wag mo muna ipagalaw sa iba baka ma void ang warranty.

nabuksan na ba brake system mo? kung yes malamang may air bubbles yan. kailangan ibleed para mawala at bumalik sa normal yung brake pressure mo. if no, dalhin mo sa casa kasi under warranty pa yan. same rin ipacheck mo baka may air bubbles at kailangan ibleed.

Better have it check right away when it involves the brakes. It could be the brake booster acting up. Try this test, after you park your car, turn the engine off. Pump the brake pedal with your feet and see if it gets stiff. It should. Next, rest your feet on the brake pedal like you were waiting for the stop light, then start the engine. The brake pedal should move down a little which means your booster is good and it could be an intermittent problem in the brake booster.

tried this test sir, bumaba naman yung brake pedal upon start ng engine., yes po, inaalala ko lang po kasi baka di rin i check ng maigi since yung problem bigla lang mangyayari without knowing when or what i did to trigger it (i just drive and parked the car), welp na ka sched nadin po this wednesday sa toyota, thanks po!


- kahapon nasabak po uli sa malakas na ulan, and nung nag papagas ako i notice, yung "check engine" light is nag stay na naka-on sa ignition (before mag light lang ng ilang sec. then mag off na) pero nag o-off naman pag mag start na engine

- salamat po sa mga nag reply

Better have it check sa casa. Hindi masosolusyunan dito yung ganyan problema. Break pa po yan.

 

[scavenger007]

the ecu is the most probable cause in my opinion
