Uneven brake pad wear?

[JMemonic]

Rubber grease. And certainly never a copper based anti-seize.

I did suggest heading to the local brake shop for the correct advise, no I would not use copper slip or copper coat, or any copper based grease, nor would I use rubber grease, its umm water based and can cause seizure and corrosion.

Oil would be fine but it wears off hence the grease, a good grease with a bit of molly in it Valvoline M, Castrol LMM, Fuchs LXM02 etc and the coating you will give is so thing as to be practically invisible.

If in doubt always get your brakes seen to buy qualified people at your local brake service outfit, they might not have the pads on the shelves but the understand how they work and how to service any faults.

Oh a foot note copper based greases are anti seizure compounds and as such are not meant for load type use they are just to stop things corroding together, nickel based grease is the same for high temp applications. Not all greases are the same and have different applications.

Use something like Wurth brake paste... it's goes a long way.

I have taken the pistons out and given them as good a clean as I can with the brake cleaner. I noticed one of the dust seals stuck out a bit when I extended the pistons with the brake lever, this could have been part of the problem.

I'm getting a new piston kit and seals soon so not worried about the rubber degrading at the moment but I will look into some grease for the sliders. All good information and I have learnt a fair bit about the brakes on my bike, which is good.

In your situation I'd suggest not just cleaning the pistons but POLISHING them. Not with a cutting compound --just get that chrome all shiney.
From My POV if you can reduce brake drag its got to be worth HP to you

Righto. Best that you immediately inform Castrol, Fuchs, PBR & all the other manufacturers of the error of their ways. There's a good lad.

I read piston seal on all of those not umm calliper slides but that's just me, I am only remembering what I was taught as an apprentice, if you have issue like I said go to your local brake servicing company and ask for their advise, also I have seen these greases jam up calliper slides, never seen it happen with the greases I mentioned, but that's just me.

Good point Frosty, sometimes the contaminants can cause pitting or form a varnish around the piston you can miss this with just cleaning with brake cleaner and such like solvents.

Just out of interest how often do you change the fluid on a race bike? I know in normal usage its recommended two years but if this is a race bike, the fluid takes a hammering and as its your safety we are taking about I would consider every oil change, it cheap insurance really.

Could wafle on about what ya "should" do or whatever. truth is unless changing it for other reasons I change fluid once a season at beginning of season.
