Bleed Brake fluid after pad swap??

[Stu_C]

I just replaced the rear brakepads on my 06 1200GS with a little help from this forum (thanks guys!) A friend of mine says I should now bleed the system a bit to see that I have no air bubbles in it. Could some one explain to me how this could happen when I never opened the fluid system??
I took it out for a gentle spin to see how it was and the rear brakes work fine!
Should I be worrying!?

No, don't worry. There should be no reason for air to get into the system when changing brake pads.

While it might not be a bad idea to bleed the brakes once in a while, and doing it when you change the pads might be a convenient time, I don't understand how changing pads simply by pushing the pistons back in can allow airinto the system.

nope leave them be,as all said before just changing the pads cant let air in and anyway if you have ABS this is defo no no

I am with the don't do it camp, leave well alone.

Cheers for the replies guys! As I suspected, if I don't open the closed brake fluid system, how can air get in! I just wanted to make sure my presumption were correct before I start a debate with him. Wouldn't want to get my facts mixed up! More though, I wouldn't want my brakes to fail!!
