Rewinding brake pistons - jimxms - 28-09-2020
I intended to have a quick look at what I was up against with changing the LS's pads/discs this evening ready for tomorrow. However I found myself almost completing the job.
One question though....
When trying to get the caliper off, the discs were so warn down that they had a rather large lip on the edge that the discs were bedded into making it impossible to simply slide the caliper off.
So instead I decided to use a pair of mole grips to pull the pads in away from the discs. This pushed the pistons in, which I assume was OK because I was only going to push them in with a piston rewind tool anyway?

Yea that sounds OK.
As you can see they are not difficult things to do - getting the disk off can sometimes be difficult as it sometimes lightly welds itself to the hub.

Cool.
One other thing before I forget. Copperslip, does it go on the back of the pad...or on the back of the shim that's attached to the back of the pad?

Both, smear it everywhere that's not the contact surfaces (obviously).

I've also found the best thing to put on sliding pins is "Red rubber grease". I've had all sorts of fun in the past when I've changed pads or disc's and found the last owner used Copaslip on the pins (With time and heat it turns into something similar to set silicone bathroom sealant)!

Also put a little copaslip on the edges of the pads top and bottom were they touch the carrier.
(the metal backing of the pads not the friction material)

why do you all use copper grease that is so old there are much better alternatives now mintex bosh to name a few copper slip is **** it will just clog up retain lots of dust and make a mess use brake grease this is designed just for brakes and is compatible with all abs systems and speed sensors and much better at keeping your pads free

If it stays slippy for longer than copper slip then I'd be down for giving it a try, but I don't believe how it can be safer for abs/sensors etc or how it will attract less dust. If its grease, it'll pick up dust no matter what.
