Question on brake bleeding and caliper replacement necessity
 

Car - 2006 EX with ABS (about 130k miles). Has never had brake work other than pad/rotor replacement.

My brother replaced his rear pads and rotors about 20k ago. The other day, he noticed that the pads on one rear wheel are down to metal. I'm going to look at the brakes tomorrow morning but I assume the caliper is shot. Would most others agree?

Also, from the information I have found from researching, I understand that bleeding is not effected by ABS so I don't have to worry about doing anything different, correct?

Lastly, since I will only be opening one brake line and will not be running the MC dry, only bleeding one wheel should not be an issue correct? But since the fluid has never been replaced, I may suggest to my brother that we bleed the entire system just to get new fresh fluid in. We'll see.

Thanks in advance.

I am betting that either the caliper pins are seized or the ebrake mech is damaged. Either way the best thing to do is just replace the caliper with a remanufactured unit. I always bleed the entire system anytime that I do brake work inpart to flush new fluid through the system and to be sure no air is in the system.

Caliper slides seized, pads stuck in bracket are the two most common issues with brakes. Clean the slides, sand all rust and crud off, and make sure you can move the pads freely by hand in and out on the bracket. If you can't, sand the edges of the pad where it rides on the bracket hardware until they move smoothly by hand.

The caliper should release fully when the pedal isn't depressed or the parking brake is off. Set the parking brake then release it and make sure both rear wheels rotate freely with no drag.
