Took my rear caliper apart today and after looking at the parts fiche on Partzilla, it looks like i am missing parts no 12 and 13. I can only assume these are important? Whatever way the brakes have been operating in the past the disc now has a lip on the outer edge so will have to be replaced. Are there many options on discs for an 87?

I have ordered rotors off of Ebay for my 89 and have been happy with the results. Here are 2 options the first is from China and the second is more expensive one made by Brembo.

Thanks Fred, anyone know about the caliper/ pad shims?

aviationfred · January 10, 2013, 03:46:36 PM

I have never had the stock rear caliper apart, so I don't know the answer to your shim problem. I do have a good, working 89' stock rear caliper. The 87' and 89' use the same calipers. I can send it to you for the cost of shipping.

Is the wear on both sides , maybe someone fitted longer pads and they didnt touch the whole disc

FJmonkey · January 10, 2013, 04:06:52 PM

I have my 86' rear brake and original rotor in the garage, I will check when I get home for these parts. It looks like they clip to the back of the brake pad and add thickness. Maybe for anti-squeal? If I have them I will let you know and will have a better guess on what they do. I will also check pad alignment to the disc, I think the lip is normal. You just have well worn disc. I rarely use my rear disc for braking, only when I am mostly vertical like stopping at a light and freeway off ramps. Others like to use the rear brake alot. My rear disc should last another 20 years.

Not much use in having them if u don't use them but then again I suppose you also have to go fast enough to make use of them!!

I must have sold my rear caliper, its not in my pile of old 86' parts. But the pad marks on the rotor do not go clear to the edge. A well worn rotor will develop a lip at the outer edge.

Maybe there are some other members with 84/87 FJs that go fast enough to use their rear brake and need to change them soon. They can identify the parts. Maybe Randy knows.

racerrad8 · January 10, 2013, 06:13:15 PM

Those are just anti-rattle shims, they are not required and the fact they are missing did not cause the lip on the rotor.

If you really want them I can get them for you.

Thanks as ever gentlemen. Looks like my rear disc is just very worn. Was a little worried about the missing parts but clearly they are not compulsory.
Had it all stripped down and cleaned and it's working as well as it should. I don't use it a whole lot either.

Mark Olson · January 11, 2013, 04:39:19 PM

A good tip on the rear rotor is replace it with the right front rotor from the front wheel of an fj that had anti dive 84-87 . same part.

A lot of us have them laying around after our front end mods.

do not attempt to resurface them. The lip is normal wear.

FJmonkey · January 11, 2013, 05:13:00 PM

I am sure my rear rotor is still in spec if you want it, apparently I don't ride fast enough to wear it out.... At least the Power Ranger suit make me look really fast.

C'mon Mark,

I've ridden with you and you do fine!!!

And who uses the rear brake anyway?

I use the rear brake all the time.... a little rear trail braking is very handy in the twisties to help tighten your line thru a turn without upsetting the chassis.... say..... when you find yourself carrying a bit more speed into a corner than prudent!

the faster you are going the better it works.

KOokaloo!
