Cant get rear caliper piston to depress!! Need HELP!!

[m3f_baltimoreM_7fa1c288c5]

Should the brake line be capped if removing the caliper for a period of time? Will the brake fluid continue to flow?

[m3f_lola1]

Yes cap it but it doesnt really matter, whole system should be flushed with new fluid

[m3f_baltimoreM_7fa1c288c5]

Yes but if enough fluid leaks down, won't this allow air to enter the system especially within the ASC system which is a bittchh to get all the trapped air out of.

Its definately better to cap them, I used platic tees last time. Your right in that it is preferable not to let any air in from up top!!
