Brake caliper pistons
Hi Guys,
I just went to change my brake pads as there was barely any meat left on the old ones. I tried to push the pistons back in after I removed the old pads but I can't seem to do it, even though everyone says they slide back easily!? Is it safe to spray some CRC or something to lube them up? I'm a complete newbie when it comes to bike mechanics so sort of just learning as I go.
Thanks for any help you can give me!
James.
