I have been working on the rear brakes of my 1997 Tdi300 Defender 90.
The rear brakes have caliper, not drums, which are seized and will have
to be replaced. OK so far.

The front brake shoes are held in place with two pins that go through
holes in the pads and then through the calipers. The rear pads have no
holes and are retain by two metal springs under similar pins which go
through the caliper alone.

I notice that the outside pads on both rear brakes are quite loose and
are rubbing on the wheel shaft (which contains the bearings etc) next to
the disc. (On a cart, this shaft would be called the nave but I'm damned
if I know what it is called on a 20th century LR!).

Is this caused by wear or has someone fitted the wrong calipers in the
past? The new pads seem to be the same as the old ones. The local Land
Rover agents tell me a shoulder inside the caliper should stop the pad
sliding through, but I can't any evidence of wear to indicate that this
shoulder has been worn away -- if indeed there is one. There is,
however, evidence of wear next to the brake disc where the pad has been
rubbing and I am pretty sure it shouldn't be doing that.

I will be able to examine new hubs and pads tomorrow, but thought some
kind soul on here might be able to offer an opinion meantime.

The springs under the pins (if it's the old RRC design) are intended to
stop the pad rotating in the caliper and doing the sort of damage that
you describe. If it is still happening with the springs in place you
need to look further. It is possible to machine the disc off the hub
(that's the word you're seeking) if not corrected in time!!

They are not rotating, merely sliding back and forth in an inwards and
outwards direction (parallel to a radius from the hub) inside the
calper. Seems like lousy design to me. And, yes, I can see the pad would
machine the disc off in time as a groove has been worn on one side!

Thanks for "hub". I should have known that!<g>

Sounds like the wrong pads have been fitted at some point.

I'm thinking maybe the wrong calipers as the replacement pads are the
same as the originals. But I'll find out today and report back.

Just back from the local LR dealers. By chance, there was a mechanic in the
parts department. He confirmed that the calipers wear in a gritty
environment.

As the shoulders which retain the pads inside the calipers wear, they allow
the brake pad to move inwards against the hub. Don't know if he was
kidding, but he asked if the pad had cut through the hub yet! Can't be that
ridiculous as there is a groove at least 1/8 inch deep on one side!

So, correct pads, correct calipres -- just another LR design fault.

Not really a design fault . considering that I look after 100+
Landrovers that use that type of pad I have never seen it happen before.

The time that the pads usually fall out is when the brake disc wears
lower than its designed thickness allowing a worn pad to move into he
part of the calliper that does not hold it correctly. Then the pad can
rub on the hub part of the disc or twist and bend the split pins enough
to allow it to fall out.

Measure the thickness of your discs and that might help you.

Considering a deep grove has worn in the caliper just where there should be
a shoulder to retain the pad I can't agree with what you say. This is
exactly what the mechanic at one of Scotland's biggest Land Rover dealers
said I would find when I spoke to him today. He said it was quite a common
problem, so it seems you don't agree.

If you read the postings, you'll see nobody said anything about pads
falling out or the pins twisting. I very much doubt that the thickness of
the discs is below spec. My guess is that they are over 1/2 inch thick.
Haynes says "N/A" for disc thickness, whatever that may mean.

Send me your email address and I'll email you the pictures. Or, better
still, I'll copy them to an appropriate site -- if there is one.

You're right, Derry. This is not a disc thickness issue.

The calipers can wear but really only if the pad is allowed to float
around. Missing or corroded springs do allow that to happen. With an
unworn calliper the springs are a fairy tight fit under the pins. The
more wear there is the less effective the springs and so it just gets worse.

You're going to have to make a judgement call as to whether the calliper
wear is excessive or not. I'm presuming that the wear groove in the hub
is fresh and that contact has not been eliminated by the use of the new
pads and springs (were the springs new, too?). Wear that has allowed the
pad to move in radially by 2mm is probably as far as you should go -
even that may be too much. If there is a definite groove where the pad
edges seat and its in the calliper material rather than rust (which is
more likely) you're probably on a shopping trip.

Your discs, callipers etc., if I read things correctly, are the same as
the old Range Rover. FTC1381 disc - recommended minimum thickness 12mm.

You are right Derry I do not agree that it is common. But what it does
demonstrate is the necessity to replace the spring clips and pins at
every pad change. Perhaps that is why I have never seen it in 15years of
maintaining LR products because I do exactly that. Even looking through
my pipe of scrap callipers none look to be worn as you describe.

Yes, broken/worn springs have obviously allow the pads to oscillate in
parallel to the radius of the hub when travelling over rough ground.

Once the calipers were removed, it was easy to see that the wear was so
severe that it was possible to slide the pads out from the hub side of
the calipers without removing the pins.

From what the mechanic said, sand gets between the edge of the pad and
the caliper and the continual movement allowed by damaged springs grinds
down the caliper. These seem to be made of softer metal than the pad.
This LR was previously used by a gamekeeper and when I first got it, I
washed about a ton of sand out of the chassis -- so that might explain
it!

The slot (yes, it is a pronounced slot) in the caliper where the pad and
caliper surfaces have been rubbing against each other is about 1/4 inch
deep!!

Both calipers and all the brake pads have now been replaced with new.

I'd go along with that - the only time I've seen the pads dropping
through is when the springs/pins are broken/missing - a maintence issue
not a design flaw I'd say.

early front brakes are the same (except 4-pot and larger pads). The spring
things under the retaining pins are there to stop the pads moving, and
should as has been said be replaced when the pads are changed - generally,
you have to buy a fitting kit as well as pads.

I've not seen wear such as you describe on several vehicles (not all LR)
which use these calipers. I surmise that it's either been used in a very
harsh environment or someone's been cutting corners on the maintenance and
not replaced the pad retaining springs. The springs should push down quite
noticeably on the pad when fitting them.

An expense that you don't need I am sure.

From your explanation of the groove.... Would it be possible that once
the pads had slid into the groove that they were then held away from the
disc and thus prevented from working, at least on the bottom 50% of the
pad ?

If someone will tell me where I can post the picture I will put one up.

Otherwise it's going to get a bit boring if I keep repeating myself and you

Went to Inverness to buy parts for the D90 again today but this time
visited the after market shop (Davidson & MacMillan). The shop owner also
confirmed that this type of wear is quite common in LR calipers!!

So either you guys are living a very sheltered life down south (Land Rovers
strictly for the school run??) or we hardened Land Roverists up are out on
the salt treated snow, then ploughing through the sand, which is
particularly hard on brake calipers!!

Pixs will be posted a.s.a.p.

yebbut, filling things full of sand buggers almost any mechanism. I doubt
any design of caliper will cope with that, TBH. And once worn, things can
go wrong as you describe. However... if you know you're working in a harsh
environment, you should be maintaining it better. Your comment about the
amount of sand that you removed is telling, I reckon.

Thanks to Austin's help, the photos are now up at
http://derry.fotopic.net/c717737.html. The third photo (copy of
caliper3.jpg) clearly shows the groove worn by the brake pad in the
caliper. I have also shown the pads so you can see the wear, which isn't
a lot considering the damage to the caliper.

For the record, this wear is b*gg*r all to do with my maintenance! The
vehicle was purchased in this condition secondhand and I have since
replaced both calipers.

cast iron is softer than steel caliper backing.

We never imagined it was. But I think the fact that you said you cleaned
about ½ cwt. of sand out of it points to the cause of failure. Previous
maintenance wasn't adequate for the operating environment, I imagine.

Mind, it's a valid point that the front calipers with 2 pins through the pad
wouldn't suffer this kind of failure.
