lol, it is so easy to determine if your calipers are akebono or not...just look on the caliper, it says nissin if it is nissin and if it doesnt then it is akebono


im thinking it is the master cylinder.
i have a faulty brake booster and the pedal never goes to the ground but it just seems like i cannot get enuf leverage to stop the car (meaning i cant lock them up either)

hmm, as for testing the brake booster, you have to follow the procesdure in the manul. it tells you to hold the brake and turn off the car, if it sinks then it is loosing vacuum.
do the same for when you start the car...
