Brake Master packed it.. Replacement options? (1 Viewer)

[vanisle3b42]

My brake master is toast on my 1982 BJ42. I figure that I won't be able to find a replacement at Lordco or Napa for a 40 series, but suspect a 60 series one would be way easier to find. Has anyone swapped a 60 series master onto a 40 series booster? Are there any good places to buy aftermarket ones that are respectful of a student budget? Ideally in Canada so I can avoid horrid US shipping costs. Thanks!

cruisercorps has a decent looking master, there shipping to canada is not to bad either. I was able to get one at a local parts store. Forget about getting one at the dealer.

I would be surprised in NAPA couldn't get a rebuilt master. They may not have one is stock, but they will get one in 24 hr.

Cool, thanks. What parts store did you find it at? I'm heading to Vancouver tomorrow (in a borrowed vehicle).. Maybe they have more... Thanks again!

Do you have drum brakes all around? Better look up the part # on ToyoDIY. Your MC is likely to be different from that on the typical U.S. spec FJ40.

Nope, I have discs on the front.. Power brakes. My truck is Canadian spec, so essentially US spec but with a diesel.

I'm running a 60-series master in my FJ40, it bolts right up. I had to shorten the pushrod in the booster as compared to how it was oriented for the original 40-series master cylinder. But I did NOT need to cut it (this is the case if you go to an 80 series booster). I just backed the adjustment nut way back and that was sufficient.

I'm not too up to speed on BJ42's - are they still vacuum assist brakes like on the FJ40 or is it hydro-assist because there's not vacuum in a diesel?

masters can be hit and miss with aftermarket. I'll cheat with many parts ,mirror,glass, door handles, etc
but certain things , especially safety related like brake masters and tie rod ends go with Toyota or at least
OEM mfg, in this case Aisin

Agree - I went with a NAPA 60-series master, and the first one failed almost immediately - a slow leak from where the reservoir connected to the front circuit. The Second master has been working properly so far, but if I were to do it again, I'd go AISIN.

Going AISIN isn't necessarily your saviour...

I had this happen to me:

For some strange reason the rubber boot supplied on the above AISIN clutch slave (which was a relatively recent purchase) seemed to be made of inferior rubber.

Perhaps there are fake AISIN products on the market and this was one? I dunno..

My experience is that these boots are VERY important. Once they fail and cease protecting the bore from the weather, failure of the seals will soon follow.

In contrast, this cheap aftermarket Taiwanese Biggs slave (purchased from Roodogs in Australia some years back) has given me tremendous service with no quality issues whatsoever:

But .... just to confirm that we're an odd bunch here and get motivated by many strange things..I'm now back to running my original ex-factory AISIN/ASCO gear (sleeved in stainless and running functional/good boots donated from other used-spares in my stash) simply because I have gotten so attached to the original parts that have given me such tremendous service over the decades (travelling all around Australia and New Zealand).

Back when I was turning wrenches for a living, we installed hundreds of aftermarket or rebuilt master cylinders we got from out nearby auto parts jobber and had less than 1% failure rate. Even though it has been a long time since I worked as a mechanic, I have yet to experience a failure on any rebuilt or after market parts I have used. I just get whatever my local parts guy can get me and I don't worry about it.

YMMV

Another interesting point is that some of the stores like Napa may also offer a lifetime warranty on their parts vs 1 yr from Mr.T. My Beck Arnley rep pointed this out to me many years ago.

I went ahead and found a 60 series one.. my local auto parts store happened to have the only one in their system. The brakes on the diesel trucks are still vacuum assist but the vacuum comes from a pump mounted to the back of the alternator. I'll give this a go for now and see how it works. The parts guy said they actually had an Aisin one in stock, so I figured I couldn't go wrong.. I sure lucked out on this one, as alternate replacement parts had to come from the far east or the US.
