Installing a New Brake Master Cylinder

[Flecker]

Ok... I did find some Master cylinder repair kits at Rockauto for both the Brake, AND Clutch master's!

I prefer to keep the OG Toyota/ Aisin bodies for these items. The steel they use is superior imo, and the bores of all the ones I have taken apart before always seem to be in great shape!

So with some basic tools (only exotic thing the average joe may not have are a decent set of snap ring pliers and a quality brake line wrench), they can be rebuilt for roughly a third of the cost of the cheaper after market ones available... and about a fourth or less of the cost of the original Toyota parts.

I might do a write up on rebuild if anyone is interested...

I'd be interested if you ever find some time. Thanks! Gearing up to tackle the master and clutch cylinders and slave asap.

im curious if anyone knows of theres a difference in master cylinders from 1st to second gen vans? they seem to have different part numbers but after ordering a spare closeout for my 87, i just. bought back my 85 and it needs one...looks pretty identical to the 87 one so ill likely be installing it...anyone?

The only difference I see is the bore size. 86-89 have a 1" bore. The 84-85 have a 15/16" bore... what's a 16th of an inch between vans?



I guess as long as it fits in the booster it would be fine imo. Stroke is the same... Worse case scenario is try it. I would happily send ya a used one to test fit from an 87 van.

ahhh nice catch, i know from the motorcycle world using a larger bore mc will make the lever feel stiff and hard, i wonder if the cailper pistons and wheel cylinders are smaller on the 1st gens..well its installed, i cant imagine its going to be an issue..

For a bike, prolly weighs in at 4-600 lbs pending on model engine and such... that 1/16" would make a difference for sure, especially with a couple of small calipers.

These piggy little vans? Not to sure, but it would prolly just grin at that 1/16"... Of course I have been wrong before. In my world theres 3 ways of doing things. The right way, the wrong way and then my way (it's just like the wrong way, but lots faster).

Hi, A noobie question.

I have a '94 Liteace (CM65 body) camper. I noticed brake fluid leak marks on the power drum. It appears that the brake master cylinder leaked one time. I don't see any fluid there now.

I found that it is Toyota part#47201 27200 but I could not find it anywhere in the stateside. Anyone know where/how I can get compatible brake master cylinder?

It looks like exactly like this. I found this one on Australian Ebay site and it says it fits on 1988-1999 Hiace.
