Brake Caliper Identification (1 Viewer)

[MatthewMcD]

I am officially half way to getting my "Knuckle Rebuild" merit badge. The knuckle rebuild went great! The issue I ran into is the front brake caliper is in worse condition than I realized. My truck is a 5/75 FJ40. But this front knuckle is (I believe) from a 1982 '60 Series. Can anyone help me identify what brake caliper I have from this photo? It has 4 pistons. I am pretty sure I can salvage the pistons but the boots are trashed and I might as well put new pads in while I am here.

Want to get the parts ordered so I can move on to the other knuckle. (And brake caliper.)

2 big and 2 small piston is stock for 76-89 40 and 60 series

Need help with brake job! FJ60 or FJ40 calipers?

Howdy Friends, Its time for a brake job on the 40. Front brakes keep locking up. I am thinking the calipers may be compromised but also curious to know your thoughts on other culprits? I have been told that I have a FJ60 front axle. What is the best route to go on replacement...

Thanks, reviewing that thread, sounds like he's replacing the calipers too. I don't think I need to go that far, but I'll know better after I disassemble the caliper and look at the pistons.

Don't sepetate the caliper , you just need to pop the pistons out to rebuid it.
But you can get coated caliper for not too much $$ if your time is limited

That's my plan, I'll measure the pistons too. The rebuild kits I am seeing don't appear to have different size pistons.

my WAG is you have a mini truck setup, solid rotor is a give away
if changing calipers, you could change the rotor to the Landcruiser vented rotor and caliper setup, or stay with what you have

for some reason I'm thinking the caliper rebuild is the same for either mini truck or Landcruiser, as the pistons are the same

 

[MatthewMcD]

@3_puppies others have said the same, though I don't know what "mini truck" means in this context. Does it mean it came from a non-LC Toyota truck? (So not a 60.) The guys at my local parts counter are pretty useless unless I tell them the right make and model.

I rebuilt the knuckle with a 9/75+ Solid Axel Kit. It was a perfect fit.

Typically a mini truck on this forum is 1985 and older(soild frt axle). 86 and later would have an independent frt suspension and i think a wider track width.

A lot of times when I'm searching for parts I'll look on various parts websites and look at various years to see if the part #'s are the same or have they changed, or they may have an application guide. Rockauto seems easy to navigate for this.

You won't be able to hone the cylinders unless you split the calipers apart. I've rebuilt calipers b4 but have not found the proper sealing glue and seals for re-assembly. Over time I've witnessed them to start seeping, so I don't rebuild them anymore. I just get rebuilt calipers.

Thanks for this @pb4ugo. I found direct replacements (with core deposit) at Napa. They have been "perfect fit" for my first rear brake job. I'll give them a shot again. Adding up the parts for the rebuild it makes more sense to replace them.

The information in this thread may help.

 

[MatthewMcD]

The Napa parts fit perfectly and the installation went so quickly that I forgot to take a photo... I'll catch it when I do the passenger side. Thanks everyone.

 

[MatthewMcD]

Wrapped up the passenger side today, though it's too hot to get my wife to help me bleed the brakes...so we'll do that tomorrow.

As promised, the caliper photo.

I messed around with the old calipers and determined that only one cylinder on the drivers side and two cylinders on the passenger side were moving.

As promised, here is the video of rebuilding my flavor of Warn locking hub with the bolt retainer.

Good work.
