silicon paste or copper slip

[fatnfast]

and there's me thinking I had better get out to the garage on Saturday and clean the copper grease off the pins on both bikes .....and luckily I have now stopped thinking about it.

Just what I was thinking . For all these years Ive been happily using copper crest on my caliper pins, never had any problems but now.....

So I read the spec of it :

DESCRIPTION
COPPERCREST is a low friction, anti-seize lubricant manufactured from a combination of micro-size copper flakes and graphite, dispersed in a water resistant grease and fortified with antioxidants, plus rust and corrosion inhibitors.
COPPERCREST provides a shield against metal-to-metal contact, preventing seizure and corrosion. Its ingredients create an effective matrix between mated surfaces and are unaffected by contraction or expansion. It fills irregularities and imperfections and resists welding, hardening or setting.
COPPERCREST provides low friction and cushions impact and shock loads. Low shear between particles reduces stick-slip, allowing quick disassembly with minimum spanner torque. It will not squeeze out of the threads, gum up or wash off.
ADVANTAGES Conforms to MIL-A-907E. Service range:- 54C (-65F) to 982C (1800F) Contains no zinc or lead. Lowers friction; reduces tightening torque on threaded components. Permits reuse of fittings; saves stud, bolt and nut replacement. Base grease optimised for brushability and stability over a wide temperature range. Not affected by contraction; expansion or vibration. Will not run, drip or settle out.
APPLICATIONS
COPPERCREST has no equal in temperature services up to 982C (1800F). Fittings that are heated red hot, then allowed to cool, can quickly be disassembled without seizure or distortion blah blah blah...

At this point I stopped worrying also.

i just checked. it's not the 1200 section.

that was a surprise

Well that clears that up then...Thanks to everyone for the replies....Tosh

Castrol red rubber grease (silicon based) on the rear calliper sliding pins. Silicon based greases are the preferred choice where there are sliding rubber components (o-rings, seals etc) hydrocarbon based greases don't work well in this situation and can cause swelling, sticktion and wear. However silicon greases are definitely not to be used on metal to metal surfaces under pressure - they aren't good lubricants and may cause galling and seizure.

Coppaslip for anti seize on carbon steels, zinc based anti seize on stainless steels.

Lubricants where lubrication is required.

I've allways used silicon grease on the pins and a very light smear on the back of the pads. 91,000 mile later and going strong ( have had to change the pads a few times and the discs at 70,000 though )
