What happend after the change in fluid the braking was ok but i noticed that when the engine is not fully revving the brake pedal tends to bottom out the same is also when traversing inclines or declines.
When on highways and when the car is running fast there is no problem of whatsoever "talagang malakas ang preno" it doesnt bottom out.
how 'bout the power brakes: vacuum booster? from what I read may konti hangin lang pumasok dito, maiiba na yun timpla ng break. this is totally independent (am not sure??) ata sa master cylinders & valves na na-check mo na.

anyway baka lang ... http://auto.howstuffworks.com/power-brake2.htm
