Where can I use copper grease around brakes, and where must I avoid it?

Short answer. Atkinson Copper Grease is labelled for the back of brake pads, threaded fasteners and high-temperature joints. It must never touch brake discs, pad friction material or any other friction surface. Check the vehicle maker first: some ask for a copper-free product on brakes, and then Ceramic Brake Pad Grease (A1-14) is the one of ours to look at.

Brakes are safety-critical. If you are not sure, have a qualified mechanic do the job.

Key facts

Where it may go (if the maker allows)

• The back of the pad backing plate, where it meets the caliper piston or fingers.
• Brake fixing threads that the maker allows to be lubricated.

Where it must never go

• Disc faces.
• Pad friction material.
• Any other friction surface.
• Live electrical parts — it is conductive. Keep it away from ABS sensors and their plugs.

Rubber parts. Caliper piston seals and dust boots are rubber. Red Rubber Grease is the one of ours labelled for brake caliper piston seals and boots. Do not use Copper Grease on them.

How to apply

1. Clean the parts and let them dry.
2. Apply a thin film only where it is allowed.
3. Wipe away excess before refitting, so nothing can migrate to the disc or pad face.
4. Bed in the brakes as the maker directs and test them before driving normally.

If you get it on a disc or pad. Clean the disc with a brake cleaner made for the job. Contaminated pads usually need replacing — follow the maker's guidance.

Caution: avoid eye contact; keep out of reach of children.
