the leak is a minor one caused by failure of an O ring on bottom of ABS unit. the fluid leaks from high pressure side of system back to low pressure side, so there is no loss of fluid from the system, but the booster pump will run continually until O ring replaced.
71,000 abs modulator and accumulator unit replaced at cost of almost $2000, including parts and labor at dealer. Modulator remanufactured only and comes with 12 months or 36,000 mile warranty. Then again at 104,000 miles it is leaking again, and needs to be replaced at an even bigger expense. Choices are to repair car or buy another car! Seems like it should be a recall item since it is dangerous impacting ability to have braking power.
