Accord 2010 Rear brake caliper won’t compress during pad change

[George]

We verified pad model.
We screwed in clockwise with cube tool. we Need about another 1/8 clearance to re-install caliper. We opened the bleed line. We even added a TINY bit of pressure with c-clamp.
The lines see cleared.
We verified that the hand brake is fully off and the hand brake lever if fully seated at the caliper. What’ happening?

You should compare your pad thickness with that of another manufacturer’s pad. Model numbers are good to check but manufacturers can make production mistakes. And while it is possible your caliper is bad, I don’t think its likely for a 2010 model. I’m pretty sure you received the incorrect pad size.

Thanks, Todd. We did resolve this.

We moved to the other rear wheel and noted that the other caliper easily retracted…. at least another 3/16 inch or more until it seated almost flush. Left & right pads thickness matched. We easily installed pads and completed job on that side.

Returning to the problem caliper… we turned piston counter clockwise to extended it. Then, opening the bleed again we were able to fully compress caliper and complete the job

We’ll re-check that caliper and pads after some time (weeks) to verify normal wear.

If anything is not right… we’ll likely replace caliper (~$75 part in NJ).

Thanks, again for your suggestion.
