madalas magfade ang brake like going to highlands tapos mabagal ang gapang pababa...

one thing you can do to improve the situation is to use a better brake fluid... some brakefluids boil too easily eh... i don't know what brand is good, but may difference yan for sure...

another thing is to make sure that your brake system is well bled, meaning walang air bubbles sa brake system mo, kung meron, mas mabilis talaga magfade ang brake...

third.... tips nila using engine braking... so try not to gas up na when going downhill, the slower your momentum, the less effort you need to stop the car.
