Rear disc caliper question

[light_duty]

So I take the rear calipers off my LJ78 to install my new pads, only to discover that the piston is pretty much siezed in the caliper. I had to use a bench vise to push the piston back into the cylinder.

I made a couple of calls to local brake shops, and was told "we usually just replace the caliper." I find this kind of lame, as it shouldn't be hard to pull the piston and hone the cylinder. Besides, the EPC doesn't provide a part number for the caliper itself, just the piston, etc. Does any one have any suggestions?

Alternatively, is anyone parting out a 80-series with a decent set of rear calipers?

Thanks!
Robin

personally i would replae the caliper, what is the price from $oyo$a? you might be able to get them from NAPA as well...

Thanks Wayne, I've found quite a bit of info in the 80s tech. Should be able to get it at Napa or Yota as it's the same unit at the LX450.

Cheers,
Robin

Yup, got mine at NAPA too. Painted the calipers with exhaust manifold paint in cast iron color:

that is normal .. ? is the first time that i listen about that.

Not sure it's normal, but a quick search of the 80s forum showed that I'm definitely not the first one to encounter this problem!

The strange thing is that all boots and seals were in great shape.

Dave, what year is your truck? I'm just trying to figure out if the caliper for the LX 450 and a 92-97 FZJ80 share the same part number. I know the FZJ part will go on the LJ78, but not sure about the caliper for the LX450. My EPC ends at 1996.

Anyway, my calipers look the same as yours.

The axle is off a 1997 HZJ75. When I went to Kragen's I asked for a "1995 Land Cruiser" and got these. Of course I had to through the usual 20 questions like:

"Six cylinder?"
yes
"Power steering?"
yes
"Power brakes?"
yes

Not that the answers make a difference, but they just make the parts drone feel comfortable looking it up in his computer.

Well, after all this, I ended up rebuilding the caliper. After I got them apart and cleaned them up, there appeared to be very little wear on the piston and the walls on the cylinder - just a couple of tiny scratches on one of the piston. So I greased 'em up and popped 'em back in...we're good to go.

Thanks everyone for your advice. I look forward to the day when I'll be able to offer some expertise on the forum.

Rebuilding Front and Rear Brakes
My LJ78 cruiser has 110,000 km on it and I'm about to do the front and back brakes plus pull and regrease the wheel bearings on the front. I'm a novice mechanic and I don't particularly look forward to something I've not done before. The manual I have is a joke (aussie Ellery for Toyota Landcruiser 1990-2007) , but at least it has some b & w pictutres of the process. My father-in-law used to do his own brakes, but he also built an airplane which he still flies. I have a former mechanic who lives next door who would provide advice through the really tricky parts. He's not keen on doing the job as he says everyone expects tuneups for free or maintenance 100,000 km later when the parts wear out!

1. Anyone find it really difficult to remove the hubs? I've not had that pleasure.

2. I can get the rotors turned for $17.50 at my local Big O tire shop which is probably cheaper than replacing them with Toyota parts. What did you folks do? I'm guessing that if there were a real problem with turning the rotors, getting something comparable from Napa would allow me to replace the rotors.

3. I'm a little reluctant to undertake this partly due to caliper and cylinder problems that may emerge. However, the $300 bill from the garage is steep! I estimate I could easily blow a Saturday doing this.

Any reflections on your brake job and whether you'd do it yourselves again? Wayne, you're not a good example as you probably do this all the time!

1) The hubs are pretty easy to get off, I just replaced the bearings on mine- three tips though the C-clip is easiest to remove by spreading it with needle nose pliers then using a small flat head to pry it off, there are 4 cone nuts holding the hub in place the easiest way to remove them is to loosen all for nuts then wack the top of the hub with a BFH, fianlly when reassembling the hub make sure you put a paper clip in the hole to hold the hub brushes down so they don't break during reassembly, also be really really careful with the outter bearing grease seal you can't replace it (even toyota doesn't have it)

Bueller,,,,,,




So are the rear rotors 80 series also??

Bump for the question

No, the discs have different heights.

Early 80 rear discs are 312/103mm (Rotor OD/Height).
Late 80 rear discs are 336/103mm (Rotor OD/Height).

70 series with 6 bolt wheels and rear discs should be 312/68mm (Rotor OD/Height).

Thanks, I have to guys at Lordco measuring up a unit, hope it fits.
