Hello,

I have to replace a caliper of the brakeclaw.
In the manual, they mention something like brake grease to help assembling.

Today, i recieved a back issue of LRO (october issue).
On page 199, there is a workshop about changing the brake pads.
2/3 through the workshop, there is a picture & a text line like 'apply a
minimal smear of brake grease'
As far as i can see, it looks the same as copper grease.
Cane anyone correct me or confirm this ?

Does anyone know why you should not seperate the 2 halfs of the rear brake
claw ?
Does anyone know the torque figure for the bolts the holds the 2 halfs of
the rear brake claw of a 92' RRC in case i still need to do dismantle them ?

Assuming I understand your English (which isn't too bad), you are
talking about replacing pistons in the caliper. You need 'rubber
grease' to lubricate the piston seals for reassembly. There's a thread
about this within the last week so have a google for it. Do NOT use
copper grease.

No, it's completely different stuff. Copper grease will damage the rubber
of the oil seals, leading to rapid failure. Brake grease is usually red.

No particular reason, but most people don't, as the chances of reassembling
incorrectly or getting dirt in there are high. I've split the calipers on a
motorbike and reassembled without too much hassle, but I wouldn't do it on a
car. I'd buy new - my life is worth more than a few quid. If you are
replacing the caliper (I assume that's what you mean by claw), then why
separate them anyway? Undo old one, bolt on new one.

Just read EMB's reply. If you mean you are replacing the pistons, then you
don't need to split the caliper. There is enough room to get the old
pistons out.

The pressures inside the caliper are huge. Easy to get it wrong, and then
no brakes.

The thread that EMB mentioned:
http://tinyurl.com/yb5vks

The grease you need to replace a piston MUST be suitable for use with
rubber.

I've never had any reason to split a calliper (claw). The seals
between the two pieces are very unlikely to have been damaged.
Replacement seals are not available from normal sources.

One half - two halves (We teach english here, too!)

Of course you could reply to Lieven in Flemish! I'm sure he'd appreciate the
opportunity to correct your errors!

I'm sure that Lieven will have taken it in the manner in which it was
intended - helpful and educational.

If one wanted to criticise the english here you could have a field day
- and if you want to critise mine, feel free.

I was merely making sure I had understood the question correctly and
wasn't attacking Lieven's command of the English language.

I was waiting for it Richard.... all the caliper kits I buy include
those anyway.

I was merely alluding to fact? that the English speaking nations expect all others
to converse in English and delight in correcting minor errors whereas they
themselves cannot be arsed to attempt to learn the languages of their
correspondents, indeed many fail to master English in the first place, preferring
to bastardise it in one way or another. Considering that English is reckoned to be
one of if not the most difficult languages to master, I think those critics have a
dam cheek.!!

English speaking nations expect other nations to speak english when
they join english-speaking forums, hardly unreasonable. If I went
into a french-speaking forum I'd be expected to speak french.

He's right - again!
 
Hello,

Thank you all for the provided information, including the English
spelling
corrections. I still wander if anyone noticed the spelling error in the
subject. ;-)

I have looked at the posting mentioned by EMB.
I overhauled a clutch master cylinder (def 90 td5) a year ago & I now
remember that the kit contained the red rubber grease.I will use that.

Still my question stands whether the product 'brake grease' is actually
the
same as 'copper grease'.

Thanks,
Lieven.

If you set aside the rubber lubricant which has been discussed, the
'other' brake grease is a high temperature grease used to lubricate
adjusters and the sliding ends of brake shoes. Copper grease does not
work well in these applications as it tends to dry out and has only
limited lubrication properties.

In the specific case that you mention, the backs of brake pads (disc
brakes), the grease does not need significant lubricant properties and
copper grease should work well - personally, I do not use any grease
on the back of disc pads.

Not it is not. Rubber grease is non-petroleum based so it doesn't
damage the rubber seals.

It stops brake squeal very well, and is an OE item on some vehicles.
