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?
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.
Fred
Is the wear on both sides , maybe someone fitted longer pads and they didnt touch the whole disc
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!! :rofl2:
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.
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.
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.
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. :biggrin:

C'mon Mark,
I've ridden with you and you do fine!!! :good:
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. :good2:
KOokaloo!

Hi Mark, would you mind checking out that rotor/disc for me? I am in Ireland so not sure what the cost of shipping but if it was any ways reasonable we could sort something out. Maybe i could have a few small bits sent to you from RPM of same value?

I will check today and let you know. The cost of shipping is most likely higher than the value of the part. Better to find something more local for a lower shipping cost. But I will check anyway and let you know. I might be able to put it on a container to England when my company ships out product. Then have it shipped from there.
Yeah, I trail brake too. I was being ironic.. :pardon:

My rear caliper is 7.4 MM, plenty of meat left on it. Shipping to Ireland?
