Lubricating front brake sliders with rubber seals
------------------------------------------------------------------

My car has just been through MOT, one of front brakes was binding.

When I checked it, one of sliders was stuck which I have freed & lubricated with some spray 3 in 1 oil & spray grease or castrol LM Grease.

I decided to lubricate both sliders & main piston.

The sliders are covered with flexible rubber seals.

Should this be ok, as I have now seen there is Castrol Red Rubber Grease ????

When I pulled back rubber seals to lubricate underneath, didn't look like a red grease had been used.
Then again they probably haven't been lubricated for last 20 years since car was made.

I don't particularly want to redo this, cleaning out old grease, oilling/greasing with rubber grease.

>>Castrol Red Rubber Grease ????

That's what I use on brake parts - I've had trouble in the past with copperslip causing slider rubbers to swell and stick.

Looking into this maybe you should only use Rubber Grease, Silicone Grease or brake fluid on brake components, as normal grease (petroleum based) can damage rubber seals over time.

It's very important to ensure that any grease used on rubber is compatible with the type of rubber. You can check compatibility here tinyurl.com/an23tv provided that you know the rubber type. Unfortunately since I retired my failing memory seems to have made me forget all the knowledge I used to use on a daily basis on this subject!
