budget brake fix questions

Responded once but the car was probably possibly parked for other reasons these cars have issues with head gasket problems you'll get all the brakes fixed and you're right at the mileage for the head gasket to let go I mean directly at the mileage so it may have been parked for other reasons that weren't discussed you know people don't really like to talk a lot when they have something that they're trying to get rid of they let you do the talking etc or information is sparse on purpose It's your job to deduce that deflection I'm sorry this has happened to you but it's quite common actually in the car business and the car world with regular people and car dealers since no difference somebody trying to acquire money for something that they have that they're finished or tired with or don't want to fool with anymore information will be sparse purposely.

 

Seymour you are in the wrong forum. This is gen2, so you might get a better response in the correct forum.

 

How much has this cost you so far? It could be hybrid battery, brake booster and engine swap needed. Just concede defeat now, sell for scrap value?

 

Actually too funny You're in the right forum Just have the wrong car maybe fix that and you'll be golden Not trying to be smart or anything but seriously backpedal now and save everything else for the future whatever that might be because right now you're just be throwing money basically into the trash but there's always that I mean if you have enough money to throw in the trash then by all means please continue so we can read about it on the generation 3 forum

 

There were several different versions of that brake booster and they don't interchange.

eBay is a terrible source for them because most of the ones offered are also worn out and the sellers generally have no idea which version they have.

Nobody rebuilds them; there is no rebuild kit. The name of the game is making sure you're not the guy who takes the hit.

I hate to say it, but it sounds like buying this particular car was a very bad decision. It's already got two of the four most expensive "usual" problems and it doesn't sound like anyone has looked for the other two yet (head gasket & air conditioner)

 

I seem to remember one of the businesses that sometimes post on PriusChat (Hybrid Pit Stop, maybe?) offering either rebuilt ones, or a service to rebuild one you send in. That's all I know; I remember looking around for any details of what their 'rebuild' entails, but all I could find seemed more proprietary than forthcoming.

 

I don't see it being "hybrid" per se, more a case of car designs, of any ilk, rushed to market with insufficient testing, and the manufacturers feeling they've got license, when there's wholesale failure of designs, to tell customers to pound sand.

Ralph Nader wrote a book once, "Unsafe at any Speed". Perhaps a similar book is needed, regarding cars rushed to market.

 

I would think if you've paid for those parts once already you should get with Toyota and see if there's anything that can be done they were new parts when you bought them I'm assuming I could be wrong I shouldn't have been that long ago now.

 

Toyota doc shows the opposite; sideways label is good:

pretty goofy way to differentiate btw.

 

You would want to test the parts on the vehicle with it still somewhat functioning with battery power and all that like you were going to drive maybe actually go for a drive what you want is a mechanic stethoscope good listening ears and some quiet when you stop You want to listen to the pieces the two pieces on the firewall and see if you can differentiate which piece is letting the fluid leak usually it's somewhere around the accumulator that's under high pressure The pump continuously runs to replace the pressure that is going somewhere with the car just sitting there generally speaking but any compromise in any part of the fluid system of the brakes will create a leak so to speak and something will bleed down then something will come on to pump it back up which is what you hear the pump running your job is to separate that out and figure out why the pump keeps coming on ie where the leak is. I would think it would be relegated to somewhere up on the firewall but before fluid moves to the calipers so when you're not touching the brakes I don't think your system is under any kind of pressure but I could be wrong The manual would help you sort that out once the pieces are off the car unless you have some kind of test rig to juice the pieces up on the bench you're just going to be sitting there looking at dumb pieces of aluminum.

 

There's also a chance that it only happened to differentiate between the 2010 units that were and weren't made with the undersized bellows, and shouldn't necessarily be taken to mean the same thing in later years of production.

 

I would be trouble too very much so thank God the solar roof 2010 generations read blew up before I started to work on the brakes which the lights were on the pedal was still fine and the person driving the car would have been gung ho to get that nonsense fixed and then the engine would have blown up right after that disastrous that's why I didn't get to working on the car very quickly because I knew pretty much the engine was going to be toast any minute thank God it was before I started working on the brakes now I have a persona here pretty much going the same way women owned people crying unhappy all that stuff just the way of the world.

 

Hybridpit.com will rebuild your brake booster/actuator/master cylinder for $550. They require you to ship yours in and have downtime. But it eliminates the problem of getting the wrong builtin ecu firmware.

The prices you quoted for new seem too low. I would email or call the dealer (and only trust a Toyota dealer for these new parts) including your vin to verify.

Installing can be difficult due to access. Even then you need Techstream or one of the few high end scanners like an XTool D8 to perform special master cylinder bleeding and associated calibrations.

As others suggest, make sure you don’t have other high dollar problems waiting like head gasket/engine fail problems or hv battery. At some point repairs might cost more than the car is worth.
