Brake Caliper Pistons

Post by glacoste » Mon Jul 01, 2019 11:31 am

Hello ....
2013 Gear Up front brake caliper pistons.
Question... are all four pistons supposed to move? I was able to loosen up the outboard pistons, but the two inboard pistons are both even and stationary.
Thanks

For the benefit of anyone else reading this later, yes they are. :lol: I greased all mine with Brembo grease to prevent them seizing up. FYI also need looking at periodically to make sure everythng's still alright in there.

I ordered some brembo grease earlier today. Read a post yesterday about using it. Cleaned up the outside of the pistions with a small wire brush. Put some fresh brake fluid on the outside of the pistons and pushed them in with a C-clamp. Did that a few times and all is good.
