FAQ LJ78 Brake Parts Cross Thread (1 Viewer)

[GTSSportCoupe]

I get a lot of questions about LJ78 brakes. So I'm going to post the Toyota part numbers here and what North American vehicles they cross to. This will make it easier and more economical for those of you trying to rebuild your LJ78 brakes. Now you can walk into your local jobber auto parts supplier and give them a make/model of vehicle that will actually be in their computer; and most likely they'll have the parts in stock.

Be aware I've given just year and general information of the vehicles they cross to; models change mid-year etc, so make sure you double check before spending your hard earned money. Please feel free to correct me if you think I've made any mistakes.

Some tips on LJ78 brakes from my experience: There is a good chance your rear caliper pistons are seized; so make sure to check them carefully. When you do front rotors, you have to take apart the whole front hub and press the rotors off the hub. This is a good opportunity to do a whole front knuckle/hub rebuild with new seals, bearings, grease etc as you're half way there anyhow (if it hasn't been done in a while). It's also a good opportunity to completely scrap the electric hubs and go to manual hubs (Source used parts from a 60 series cruiser to do this: spindles, bearing hubs, freewheel hubs, axle nuts and all associated parts). If you don't, make sure you follow the manual carefully to not break off your e-hub brushes. Finally, when you bleed your brake system, don't forget to bleed the load proportioning valve also, as air gets caught up in there otherwise and will leave you with squishy brakes. Use Toyota manual RM183E (lots of links on this site) when you do your brakes.

I can assure you that properly working LJ78 brakes are excellent. I can lock up 35" tires no problem.

Thanks Nick. I printed this and put it in my parts folder for future reference.

I'm getting set to do the emergency brakes on the rear. Will an FJ Cruiser kit work for that, too (pads, cylinder, springs, etc.)?

I just looked at the Megazip EPC drawings for a 2007 FJ Cruiser next to a 1990 LJ78, and honestly the e-brakes look very similar with many of the key parts crossing over. The shoes don't, but may work anyhow. Take a look at those EPC drawings yourself and see what you think. I think it's worth a try.

Have you inspected the e-brake parts to see if they're really worn out though? Maybe you can get away with cleaning/lubricating/adjusting?

Thanks again. I haven't opened them up yet, so I don't know that there's anything specific that's wrong, I'm just not getting a whole lot of braking force from them.

Do you know if it's necessary to pull the axle shafts in order to get access to the brake internals?

It's been too long, and I don't remember, sorry. I think I did my rear rotors about 8 years ago when I first bought my truck and knew nothing. It's a hazy memory at best.

 

[AirheadNut]

I'm going through my rear brakes right now, after sitting for over 2 years they are all seized up. The emergency brakes can be disassembled without removing the axle shafts, but there isn't much clearance to get the little spring retainer caps off. I have yet to see if I can get them back together without removing the axle.

Also, this info is super helpful @GTSSportCoupe ! Thanks a ton!

Some brake line info. Front and rear. These are all 2" longer than stock for lifted vehicles. I can do some research later and find factory length cross reference.
Extended brake lines for the LJ78 are :
You need 2 of these.

Toyota 96940-34705
or
Bendix 78575
or
Dorman H380535
or
Raybestos BH380535
or
Wagner BH138042

I know the Dorman are available on Amazon

Thanks for the added info Onur. I failed to measure them before I put them on.

I’m done with the oem things. I’m trying to get like wilwood front caliper. I’m wondering if there’s any vendor who sell them?

Thank you for doing the legwork in figuring out the cross reference stuff, doesn’t seem like Toyota like to keep the same numbers even though the parts remain the same. I have already used these numbers you provided for my pads. I need a master cylinder and MegaZip no longer carries them and eBay has some that have different numbers and slight differences but no part number matched. Do you know if anyone has installed one from a different model that has worked. As you probably already know even here not a lot specific brake info other than your post. I just rebuilt it and it’s actually worse now than before, leaking out towards booster as was previously so I am guessing the cylinder is scared and new seals didn’t fix. TIA

I am facing the same exact problem. I wanted to do the job myself but it's very cold in the garage so taking it to my mechanic...hehe.

I called napa today in Vancouver and the only part number they said existed in their system was the 04465-60030. The napa part number for this is ADO AD7549.

@GTSSportCoupe do you know any rock auto part numbers for front brake pads or any alternatives for that matter ?

When you go into most auto parts stores you can't use Toyota part numbers. Instead, you need to use the Make/Model/Year cross that I supplied in my first post above. Once you do that you'll find everything you need at Napa or wherever.

@GTSSportCoupe in your original post you mentioned that the front pads are compatible with 1989-1995 4runner pads. I compared all the part numbers on rock auto and it looks like 1989-1991 4 runners have different pads numbers than 1992-1995. They look pretty similar, maybe its just different retaining clips? I'm confused which ones will actually fit, are you sure that any brake pads from 1989-1995 4 runners will work? Thanks for the help, much appreciated!

Not sure on the differences exactly with the various 4runner pads. I think I've always gone for the v6 ones if I remember correct.

Edit: The V6 calipers and pads are the ones to get. I updated the first post to reflect this.

 

[GTSSportCoupe]

I should also mention I've replaced both my front and rear flexible brake hoses (to calipers) from North American models also. It's been a while, and I can look closer into it if anyone wants, but pretty sure the fronts crossed to 60 series Landcruiser and rears crossed to 80 series Landcruiser.

Great thread. Thank you @GTSSportCoupe.

I realize this information is for crossover parts for an LJ78.

However, would any of the components listed (front discs, pads, and calipers) work for my 1996 HZJ75? The truck has the 8" high-pinion axle if that's relevant.

Thanks!

Edit: Never mind. I just cross-referenced the part numbers listed above, with the part numbers for my vehicle, and they are the same. It looks like the front brakes are interchangeable for my HZJ75. Thank you!

My 1991 LJ78 has rear drums. Any details on wheel cylinders? I thought it was the same as a 60 series. Thank you
