    Hello

    I have a 2005 Prius with about 350K miles. A few months ago I was driving home from work and got several dash lights and the brake warning buzzer. After checking fuses and relays I decided to replace the ABS pump/module. I bought a used one from Ebay and installed it, and bled the brakes using tech-stream. I am still getting codes C1364 (with sub-code 225) and C1365. If I clear the codes the buzzer stops and the dash lights clear, and the car drives and stops normally. All is well until I turn the car off, then the buzzer comes back with the dash lights, and the brakes are very hard to use (no-regen).

    Could this be the result of air still trapped in the lines? I got very little fluid out of the back brakes when bleeding them. The brakes feel fine when the codes are cleared. If not air in the system are there any other things I should be checking? Hoping it's not a bad ABS pump since a new one is very close to what this car is worth.

    Thanks

    Bart

    There is so much labor involved in this repair I don't think anybody should risk putting in a used one. These used ones that are on the marketplace could very well be the broken ones that were replaced.

    And at this point the used ones are getting much harder to find... However there's a 3rd option that we once thought impossible, which is rebuilding and replacing the seals in your existing pump. There's a guy in Los Angelos who started doing them. Hopefully others will too... Way better than rolling the dice on a used one.

    You pretty much get what you pay for. The guy that was pushing Chinese made new hybrid batteries on here for $1600, only to have them last less than 3 years. Everyone jumped on the band wagon on this new and cheaper option before knowing its longevity. Horrible investment compared to new Toyota OEM batteries.

    The only outfit I ever read about here that was offering that service is now, according to a recent report, not strongly promoting it. I had never seen them offer much detail on exactly what they had decided the problem was or how they corrected it on rebuild—which I can understand the commercial reasons for, but which also leaves open a bigger potential for disappointing outcomes than if a process is better disclosed and has more eyeballs on it. It seems, sadly, as if this might have been a case in point.

    Yes, but if someone with a machine shop can figure this out and reliably rebuild them it would save all of us alot of money and make them alot of money in the process.

    Are you referring to the one with the cylindrical batteries? I remember telling people at the time not to trust that technology since the aftermarket Honda Civic Hybrid I IMA replacement packs which used it were none too reliable. The company that had the best reputation among that group was BumbleBee batteries. Gone now, they were at some point absorbed by LKQ and now are part of Green Bean.

    Figure it out, and reliably rebuild them, and give us a sound basis for believing that they have.

    The shop offering the service before seemed to want to be trusted with a brake actuator and $550 without disclosing their findings or methods, and I remember my gut feeling that, on those terms, I'd probably still just buy new if I needed one. Sadly, that more recent update leaves me thinking my gut feeling wasn't wrong.

    Now, I've been an active proponent here on PriusChat of a fuel-injector restoring service, but a key difference there was that Rich was pretty open about how he did the job, and would send the injectors back with a printout of before-and-after test results. So, his strategy for making a buck didn't depend on keeping secrets and being the only guy who knew how to do it, but only on being open and dependable and good at doing it.

    Maybe sooner or later someone will figure out the brake actuator troubles and take that same kind of approach.
