Master Cylinder Reservoir Replacement?

The master cylinder reservoir in my 1999 Tacoma appears to have a lot of cracks, not leaking, and can't feeling them though.

I've looked around for a replacement reservoir but other than OEM I can't find a match. Seems like a lot of after market master cylinders don't include the reservoir either.

Any ideas for a good replacement? Should I just get a new master cylinder, if so any suggestions?

 

Looks like the aftermarket master cylinders I see on Amazon (Dorman-made in China) come with the reservoir. After reading the reviews I wouldn't use one of them in my truck, but if you can't find a reservoir you COULD swap just the reservoir out, that way you keep the well made OEM cylinder, if anything just hone the OEM cylinder out and throw a new seal on the rod/shaft. Only thing I would use from an aftermarket brake master cylinder would be the reservoir. Could also try to find a reservoir in better shape than yours from a Pic n pull, etc. and swap that reservoir onto yours. If you're gonna do that might as well do a brake fluid flush since you'll have system opened up anyways and will need to bleed regardless. Anywho, some ideas

 

Thanks for the info. I checked out Rockauto too and they only have full master cylinders also, no reservoirs. For some/most of those it isn't clear if they include the reservoir or not. To make it worse, the OEM part number for my non-abs model, 47220-04020, is discontinued. The ABS version, 47220-35040, is still purchasable, but I don't know it they fit...

 

I did this with the power steering reservoir. A new reservoir by itself would have been some price like $200+. I bought a new cheap China made pump and reservoir for $50. I shelved the pump and used only the new reservoir. Works great.

 

That's prolly where I kyped that info from thenDid you post it up here in TW? I prolly took it from that if you did haha
I don't want credit just sharing info ideas

 

I can't remember.. Its all good.

 

OP,
Purchase a newer version of the OEM unit. I still retain my OEM MC unit after a SAC which includes a 231mm Tundra brake upgrade up front and discs in the rear via Diamond axles.
This things stops on a dime.

 

Yours is sweet, I agree. But all he wanted to do was to get rid of the superficial cracks in the existing reservoir but I mean how could you not recommend SAS having gone that route

 

Cruiser,
I guess what I meant was that even after my mods, I retain the OEM unit and it functions well.

 

So part # 47220-35040 fits the non ABS master cylinder too? Is there a difference in grommets?

 

Did you ever find the answer to this question? I'm in the same bote, trying to replace the MC reservoir only but the the non ABS version is no where to be found and was wondering if the ABS version will fit the non ABS master cylinder.

 

Haven't tried it yet. I just decided to wait until I get a leak

 

Just wanted to add to this for future reference for anyone looking. As I like clean plastics under the hood, I've replaced everything except for the brake fluid reservoir, so I pretty much went through the aformentioned search of knowlege in this post yadda yadda.

Non-ABS reservoir - 47220-04020 (discontinued)
Non-ABS reservoir grommets - 47255-20010 (available)
Non-ABS master cylinder w/ reservoir - 47201-04030 (discontinued)
ABS reservoir - 47220-35040 (available)
ABS reservoir grommets - 47255-16010 (available)
ABS master cylinder w/reservoir - 47201-3D250 (discontinued)

Just for the record, the ABS reservoir model WILL NOT fit the non-ABS master...I've done a ton of research and finally said the hell with it and ordered the ABS model in hopes it would work, it definitely does not. The inferior stubs as you'll see attached in the photos don't work with the non-ABS grommets, and the ABS grommets with the ABS reservoir don't fit tightly in the master. If anyone has any specific questions, please don't hesitate to reach out.

EDIT: Note with reference to the rubber grommet, the "shorter" one is the non-ABS version.

 

Why cant you just buy a generic non abs and swap out the reservoir

Hey Silver...that's definitely worth looking into and I've contemplated that, and believe me, I've looked at no less than 10 aftermarket masters that have the reservoir attached...the issue there is, the business end of those masters are the only part that matters as far as the manufacturer is concerned and more than likely the reservoir itself where it's attached could be any design and more than likely they are proprietary and all different. It's mind-blowing to me that the ABS factory reservoir is different, although it functions the exact same, there is no functional difference internally or externally.

The questions remains, of why that reservoir is discontinued, and for that fact, even the non-ABS master with attached reservoir from Toyota is also discontinued (47201-04030).

 

I have a factory non abs regular cab, but it appears I have an abs master? I’m also looking to change my reservoir as it’s seen better days. Was the one you purchased from Toyota?

 

Yep, straight from Toyota...I essentially wasted $160 approximately with the 2 grommets. I don't think that's an ABS master, but once again, the only way to know is to pull it off...it's not really hard, I just siphoned what was in the reservoir out and put some rags around the bottom...you take one little screw off and then carefully pry it off, then you would know based on what the inferior stubs looks like.

 

Gotcha. I wasn’t sure how to figure out which were abs vs non. I figured since it had a plugged port from the factory, that it would have something to do with abs

 

I took a couple quick pics, I'm pretty sure we have the same master, mine looks to have that same "port" as it were..
