Those were the bad old days, with budget cuts they don't do it anymore. No safety, no emissions for older vehicles, almost like a free country. Of course the governor is now in the federal pen, so I don't expect the holiday to last. :frown:
 
Our ex-governor is out of the fed pen now (he did have to step down while in office because of it) Isn't it a wonderful country.:rolleyes: So Jim is your's in one of the country club prisons like our's was.

BTW, my brakes may be back working again. (And I probably just jinxed it by saying that. :rolleyes: )

Put on the new hoses, bought another 20 shares of stock in my favorite brake fluid manufacturer, and soon you might see this . . . .

I'm sure the FJ25 bad brakes thread will somehow live on forever. ;)

I'm sure your long string of successes will surely lure another victim into retaining their original brakes. :beer:

Geeeez . . . . I wouldn't wish this evil curse on my worse enemy. :eek: :eek: :eek: :eek:
 
Something's really wrong here . . . .

Hmmm . . . . what does it mean when I've driven my 25 for the past four days (about 150-200 miles total) and every time I step on the brakes, I get this solid good pedal and the truck comes to a smooth controlled stop?

Then for some odd reason, after I park it, the shoes won't lock up against the drums, thus making it possible to drive subsequent times.

And to top it all off, my brake lights no longer remain on after it's parked, the shoes aren't requiring daily adjustment, and the guy at NAPA gave me a strange look yesterday when I didn't buy six bottles of brake fluid.

I'm not too familiar with this peculiar phenomenon. What does this all mean?? :confused:
 
It's getting cooler in Hotlanta? Global warming > cooler temps > Better Brakes! :flipoff2:

We're still having what you'd call "CT summer weather" here in Brunswick (the other side of the world from Hotlanta). So I guess I can now make this official . . .

Alternate wheel cylinder part #

In order to save the money and time of re-sleeving my OEMs, I went with the rear wheel cylinder housings from an '82 FJ40.

From Advance Auto Parts, the aftermarket cylinder (made in Italy) is part # WC37690 ($15.95).

As mentioned earlier, I stripped the guts from the new one and replaced them with the original FJ25 piston, spring and brand new 1" cup. Very minor back plate mod to accomadate mounting, and only real difference is the 5/16" bleeder valve rather than 10mm.

I have to know what the minor backing plate mod is. I ordered OEM 82 FJ40 cylinders and don't see how you made them work in a safe manner.
The bolt mounting holes on the replacement WC are set about a total of 1/16" narrower than my backing plate holes. So I just did some very minor dremeling and they lined right up. And, the big center hole was filled perfectly.
 
Mike, I'll swing by the NAPA warehouse and check them out so we don't have to order them in. Tried this morning when I picked up the drums................there dang computer was down.:rolleyes:

Steve, tried this one out and it didn't work....although the one I got was Chinese. Boss on this one was 1.360", the Toyota ones are close at 1.375". Anyhow the holes in our backing plates and the original cylinders are 1.500". :confused:

Must be a pineapple thing. :D

Since my last post on this, I started thinking the very same thing. Maybe it is a pineapple thing or something (or a Chinese thing, or an Italian thing. :rolleyes: )

There've been enough other weird differences along the way to almost believe my backing plates and other brake components actually might be slightly different as well.

For instance, when I got the brand new (US OEM) brake hoses last month, the fittings on the new hoses didn't even come close to fitting my old wheel cylinders. (I would've had to use adapters to make the connection if I had stuck with the original WCs.)

However, the new hose(s) fit the T-connection splitter atop of the rear axle perfectly. Go figure. :confused:
 
If I can work up the courage to disturb and possibly jinx my otherwise perfectly-working brakes :eek: , I'll pull a drum off and snap some pics.
