Copper grease and front pads

[bwhiti]

Hi everyone sorry I haven't been a big poster but I do log in and have a read everyday.

Anyway yesterday I had my first go at changing my front disc pads on my marauder 125. I wasn't sure where to put the copper grease so I didn't use it. Nothing seems to be squeaking or screaming so I was wondering would I cause any harm not using copper grease and where do you put it I assume between the thin plate and the back of the pad?

Thanks 4 ur help

Yeah....normally you put a smear of it on the metal plate at the back of the pad. It can help reduce squeal...but also stops the pad backing corroding and seizing or sticking to the pistons when it comes time to replace them again. I also put a thin smear on the guide pins to stop them corroding and allow the pads to move smoothly through them.

Copper grease is a legal requirement, for professional brake tech's in this country. It helps prevent brake seizure from corrosion caused by winter salt. You need to read up and apply. Less is more tho, beware of contaminating friction surfaces.

Ok Colin I'll take the pads out again on Saturday and apply a tiny amount to the back of the pads and the pin that the pads attach on. Thanks alot

and the pins the caliper slides on. Tho I use silicone grease there. All exposed moving parts need protecting from the salt and weather.
