Brake booster/accumulator compatibility?

Sebring, FL

 

Would this follow for the actuator as well was there anything that was an indication of the new actuators that had the issue fixed?

 

You're going to be buying this stuff generally from Toyota anyway or a Toyota qualified independent seller that is connected to the network so you should be getting the latest newer parts not new old stock from before the update. I would think those would be all long gone by now just saying I don't think there's a quick fix to straighten it out so you just want to make sure of your production date of the part you're buying that it's well after the manufacturing date of the physical car you have then you should be good to go

 

When it comes to brakes on a car, like YOUR car, better to be over cautious than under!

 

I know it’s frowned upon but if I wish to buy used could I just cross reference the vin of the part to the car and then verify the date of when they fixed said issue?

 

As Tom says, buy new from a dealer, an online Toyota dealer or from an independent who buys from a dealer. They will verify you get the correct actuator - there are at least two for most years and different part numbers for a v or c.

There is no vin based production change that I know of for the actuators. Almost all gen3s were eligible for a free actuator for 10 years 150,000 miles.

 

ok, so that gets all that out of the way the issue I'm having now is this. which part number is the right one? The only difference on the website between two is the price and the picture is angled differently. Still, my understanding based on what I've observed is that Toyota supersedes part numbers by going down soooooo. would that mean 47050-47140 is the most current iteration of the actuator?
47050-47140

47050-47150

 

You can go to an online Toyota dealer and input your vin to get the right part number. Or just call them.

 

First I replaced the pump because it was cheaper. NO GO. Master cylinder was bad, but local dealer did not bleed new replacement properly so it had a whooping chirp whistle sound. Next the cheap replacement pump failed. I found air in the pressure line. It had been causing the whoop. My orig. pump is good, and now I am HAPPY.

 

duh - at 4 am the solution came to me, as often happens ! The 1/2 inch draw-down of brake fluid from the reservoir is what pressurizes the accumulator ! So I have no problem... other than seemingly soft pedal. ASAP I will stomp on a demo vehicle brake pedal and see how it compares with mine.

 

I'm only 83 yrs old -- how old do i have to be to become a senior member ? ?

 

what U have labeled the BRAKE BOOSTER ASSEMBLY I have been calling the brake master cylinder.

 

I think I'm finally out of the woods now, after about a whole year dealing with the brakes issue ! In the mean time I had to replace the head basket !

 

Glad your brake controller problem was eventually corrected.

Sometimes you end up right even if it took several wrongs to make it right.

Naming is usually Brake Booster Pump and Brake Booster Assembly. But Toyota must have been confused as well - so now many of their listings are more aligned with your terms.

However Head Basket may never catch on.

 

Time on list I think it has nothing to do with your age If you sign up and you're 101 you'll be a senior member when you're about 102 a half a year or something I can't remember how long it took I'm just coming up on 70 and has nothing to do with your personal age.

 

Hmm, but PopCorkOff joined in 2016, it says. Eight years here and still a junior member? Just a youthful spirit I guess.



The gizmo on top can legitimately be called any of: the master cylinder, the booster, the actuator, the skid ECU. It includes all those things, and all those names get used for it one place or another.

The gizmo on the bottom can legitimately be called the booster pump or the accumulator. It includes both those parts and people use both those names.

The main trick is remembering that "booster" (a legit name for the top gizmo) and "booster pump" (a legit name for the bottom gizmo) can only be told apart by whether the word 'pump' is there or not, so using those names calls for being extra careful with the wording.

 

That's why I talk about the part that hooks up to the pedal the part I'm moving when I step on the pedal and most cars that generally starts moving fluid with rubber seals and the like until it gets to a point where computers and motors can take over I guess or at least in my vehicle I think that's the way it is in the 2. But apparently in these type of assisted systems a fluid leak where the pedal activation happens is pretty much quite rare or nonexistent or whatever unlike older master cylinder type of brake system cars so basically completely different animals You're not going to be doing much fixing on these you'll be replacing.
