Do you butter your brake pads with copper marmalade?

Hi,

I thought I should just make this post as a reminder to people of the amount of copper based grease (coppaslip) to use on the front brakes while servicing.

That amount is none.

Please do not apply or use any copper petroleum base greases to the front brakes of the UP! or cars in general (generally, unless specified) Please use the correct grease for the application. e.g.


There are two reasons for this
  1. The grease will eventually wash and flake off with the future grit and dust around the brake caliper and then make contact with the friction surface. This will cause a "loss of braking function" that is very bad.
  2. When used on slide pins, the copper grease will start to eat away at the rubber seals and bearing slide surface and will eventually bind the caliper in place causing binding calipers.
Source;


Copper grease should only be used on surfaces that will seize up as they are left for a long time, e.g. the iron disk against the steel hub.

Also, never put anti-seize grease, copper or otherwise on your wheel bolt threads or any other critical faster in that case,! e.g. head bolts.

Rear dum brakes are slightly different and will require some high tack grease on the contact points.
