    Hi,my prius has the C 2153 c 2152 and C 2156 codes, a beeping sound and warnibg lights on the dash,when doing some inspection i noticed that the accumalator is labeled "do not replace" so what does that mean since the scanner says low pressuer from the accumalator,the rear breaks are not working and the break pedal pushes back.

    UH OH..... you might need the dreaded pump and master cylinder replaced. I had to on mine..... I didn't have codes just pump running all of the time.
    How many miles on it? The rear brakes run off the pump.... front pedal pressure.

    Well,the interesting part is that the break master cylinder is separated from the booster accumulator, so i don't understand how to go about it, and now you can't hear the pump sound ,it has 121788 miles on it,so how do I know what exactly is wrong,is is theatre cylinder or the break accumulator booster?
