Hi Guys

i've recently taken my brake calipers off the discs and had them hanging. Like a absolute idiot i forgot and put my foot on the brake and now the pistons has come out and its not going back, in why is this do i need to open the brake fluid reservoir and then try it agin or maybe get a small g clamp and push it back in .

Thanks Mani

G clamp or put a spanner all the way across it and try gripping it shut with your hands, usually works if you strong like Hulk.

Never force brake fluid back the line! Always open the bleed valve, and let the fluid displaced by the piston escape as it goes in.
If the piston has come all the way out, there's a good chance that you've got some grit/dirt into the bore, so I'd advise a clean up first.
