Which is BEST Replacement for the Rear Drum Brake Cylinder?

[Reaccion]

Hello guys! Before I buy anything for my Vibe, I always want to double check with you guys . So, I was changing my rear brakes for my 2003 Vibe AWD and noticed that one of the drum cylinders is leaking a little bit. So, I went online to find the OEM replacement. This is really confusing. For Toyota, I got the OEM part number to be 47550-42020 but the brand shown is “Aisin”. For the Vibe, I got the ACDelco 18E840. Also, the Dorman replacement is W370038. I was wondering, is the Aisin the official Toyota replacement brand? If it is not, please let me know which one is the best replacement. I need to do this as soon as possible! Thanks guys!

Yes, Aisin is an OEM supplier for Toyota. Both the Toyota and ACDelco part are likely the same Aisin part.

Great! Thank you for the information. After reading your piece of advice, I bought the following items on eBay (A set of 2 for $51.77 free shipping): http://www.ebay.com/itm/350831264000?ss ... 1423.l2649" onclick="window.open(this.href);return false;

Hello guys! I just want to double check with you. What are these? I ordered 2 Rear Drum Brake Wheel Cylinders Aisin 47550 42020 and I got these:

This is not what I order. Are these original Aisin? Should I return them?

AISIN sold the Brake divisions (or parts of the division) to ADVICS. Since they are rear brakes I wouldn't be concerned. I have purchased after market brake pads and calipers for years and rarely noticed a difference.

I got a Beck Arnley and a Raybestos cylinder for my '06 and they are absolutely identical. They are all likely made in the same factory in China and just packaged for each company.
Yours appear to be made in Japan which is a good thing.

Okay, I understand. No wonder they have the same part numbers. Yes, my whole concern was to purchase something OEM.

Okay, I understand. But when I purchased this part on eBay the seller was offering it as "Cylinders Aisin 47550 42020". I understand that there were other good potential companies but I wanted to make sure that I was getting the same OEM quality with this purchase (Advios WCT-081) than if I would have actually bought the "OEM Cylinders Aisin 47550 42020". Because if I did not, the seller is advertising one thing when he/she is delivering another one.

You know I'm not sure you'll have an argument with them. Aisin no longer makes them, but this company does and they are made in Japan. If you were so concerned about OEM buy them from GM or Toyota stealership and pay 100% more for the same part made by ADVICS with a Toyota or GM badge. Like buying a used Vibe VS Matrix...same thing but the Vibe is less $1 to $2K less.

Yes, I found out that this part number "47550 42020" used in the seller description, is the Toyota OEM part number which fits Matrix, Rav4 and so on. That is why I bought these thinking that I was getting OEM Aisin from Toyota. As you could have read, knowing that OEM Toyota cylinders were made by Aisin was the whole point of this thread. It is like Denso, which makes the OEM O2 sensors for Toyota.

Well, I had the cylinders installed. The good thing about it is that the old cylinders had the same part numbers on their rubbers as the new ones. Also, the "Aisin" printing was also on both old and new cylinders. They were both identical. That made me feel more relaxed.

The garage is in the back of the Vibe. I had it full with my cousin's K24 engine and transmission and his 98 Civic ready for a swap.. My cousin and I installed them cylinders in about one hour. I needed my brakes asap!

Good job. I'll be doing the same thing as soon as it warms up a bit. It's been -20°C (-4°F) or so most of January.

[tpollauf]

Nice job! That situation reminds me of when I had NO garage and had to do everything outdoors. That was some 25+ years ago Guess when you have no choice in order to keep the Vibe drivable you'll perform the work no matter what the climate is.

Woow! That is really COLDDDD! It was really cold here too when we did the cylinders yesterday, but not that cold. I think around 29 degrees

I actually do not own this little garage. I rent it. They have like 25 garages one next to the other. They are all rented. It is very quite to work in or out of the garage (Of course, when it not that cold). Great neighbors too! I do not really like anybody to work on my Vibe unless it is really necessary. I feel more confident when I do it myself, especially brakes. Besides that they charge a lot of money for any jobs, some mechanics would not put the love that we Vibe owners would put into anything we do to our vehicles...

I had a water pump crap out on a 71' Firebird in winter. The highs were 10 Deg F no garage and working in 20mph winds. That was really cold.

I had a water pump (removed) out on a 71' Firebird in winter. The highs were 10 Deg F no garage and working in 20mph winds. That was really cold.

Wow! That was really for such of complex job! Again, I guess you did not want anybody else to touch your car...

[Salsa Guy]

I'd rather change the water pump on it than the Vibe/Matrix. You have room to work on Firebird.

I had never worked on a Firebird. However, I find the Vibe/Matrix easy to access to work.

[Salsa Guy]

I've changed water pumps on both and '71 Firebird is much easier.

I see.
