Yes it's me again Smile What would be the best grease to use for drum brake parts?

I have on hand: copper, silicone, lithium, teflon and molybdenum. Will any of these do the job?

Also, I read somewhere you can put grease on the pads to stop them squeaking. That doesn't sound right Shocked

Something claggy and sticky?
Only stuff I ever used was a small amount of copperslip. For me though I would dismantle them regularly and clean them through - it ensured maximum effectiveness.
Edit: Do not put grease onto friction surfaces ar anywhere where it could potentially reach them. Use grease sparingly where the cam travels through the holder and a tiny bit on the cam where the shoes are squashing it.
Tiny amounts and regular servicing is key.

Drum brakes have SHOES. Disc brakes have PADS. I never ever had shoes that squeeled.
You're confusing this with disc brakes - I'm well aware that you watch YouTube vids for advice but whatever you do, do not watch Delboy doing things to bikes and copy it. Actually don't copy how he uses tools or anything.

I use normal grease on the cams where the pivot in the brake plate and a spot of copperslip on the actuating faces of the cam.

Off topic but don’t put copperslip on the back of disc pads. It causes dust seals to dry out and swell.

Well, it will stop them squeaking, thats for sure!

I cannot believe there are people so stupid to grease brake pad contact areas and if there are, Darwin's theory will be proved again.

Therefore chap, I will presume you just wrote the above to get a rise out of old duffers who can't see the funny side of that statement.

Well done, you properly pushed my buttons. Thumbs Up

Castrol LM. A thin smear...

Edit: Now replaced by/renamed as "Castrol High Temperature Grease".

A thin smear... where the piston pushes, on the back of them...

I use copper grease only on brakes.

Clean it first. That's the important bit. Brake cleaner and a stiff brush.

Then a thin smear of copper grease on moving parts, the cam and its spindle are the important bits. If you use lots it will just attract brake dust and make a mess. Copper grease can burn off the greasy bit and leave a coating of copper.

Strip and clean once a year, or every tyre change.

Haha! I meant the surface of the shoes. They are the pads, no? Smile

Regarding advice ofc I watch YouTube. You get a good idea of whether someone has any confidence and enthusiasm about the job in hand but there are exceptions like Delboy and Americans Wink It's either that or bug you guys all the time. And the other bike forums have too many autists for my taste Laughing

The grease on pads was on some on-line article I (mis)read. Poor wording vs ignorance, a potential lethal combination!

I use black molybdenum grease.

As a general rule, high load/low movement (eg a metal pivot on a steel bush) = Black Moly. grease. Low-load/High speed (eg wheel bearings) = LM grease.

The molybdenum is good for this application because it's metal on metal. The molybdenum disulphide will hang about and lubricate the metal-on-metal even if the grease film is broken/missing.

If you know any car mechanics, see if they have some leftover sachets of black grease from ball joints/track-rod ends. It has a very high moly content, really good quality grease.

You need to grease the cam pivot well (some older bikes even have a grease nipple here) and a THIN smear on the cam and pivot pins. I usually put a very thin smear on the springs to stop them rusting.

You shouldn't touch the friction material with anything but brake drum (with the possible exception of a bit of emery paper/chalk if you have to profile them in).

I put copper grease on the splines to stop them seizing.

Thanx! I have lots of moly grease - it gets used a lot in eBike motors.
