Changing one caliper... Bleed whole system?

[WOTDSM]

Well I found out why my brakes would "drag" (stay engaged after I released the pedal) my drivers side rear piston siezed up! Ahh! At least it's under lifetime warranty... Anyways, I am changing just that caliper on tuesday and wanted to know, do I need to bleed the whole brake system or just that caliper? Hopefully its just that caliper! Less work ftw.
Thanks.

It is not necessary to bleed the entire brake system when servicing only one corner. Just replace your caliper(check the brake hose too, & replace as necessary), & gravity bleed just that corner(remove the lid from the master cyl. & fill it, open the bleeder on the new caliper, & let it drip until it`s bled completely.

This also depends on what calipers are replaced. Since you are Doing only one of the rears, bleeding just that caliper will be fine. If you were to break either of the lines in the front you SHOULD bleed the entire system starting from the furthest caliper away from the Master Cylinder then work your way closer.

id just do them all, its not really too much more work.

Thanks for the help guys, I might end up doing all of them just because my brake fluid could use changing.

Just bleading the one caliper you replaced will work. but I would bleed them all. its a good time to flush the whole system anyways. You should flush the brake fluid every 2 years anyways. Change the caliper, suck all the brake fluid out of the master cylinder then gravity bleed the system till you see nice clear fluid
