Good afternoon!
I have been having an intermittent brake drag issue on my 1997 Honda accord lx. Short trips are fine but I have noticed it hanging up if I do a lot of stop and go. It doesn’t lock up completely but it makes it difficult when taking off from a stop(manual) or going up hills. The brake pedal gets very firm as well. It is only the front passenger caliper that is sticking. So here is some information on things the previous owner has done and what I have done.
Previous owner: Replaced wheel bearings, front calipers, rotors, pads and rear shoes. All work was performed by a reputable shop.
Things I have done: I’ve read that the rubber line that runs from the hard line to the caliper can become damaged internally and act like a check valve. I replaced that line and re-bled the brakes. I thought for certain this was the culprit and was surprised when it started doing it again.
I have also done a few brake booster tests and everything seems to be in order.
I am stumped. I suppose it could be the master cylinder or the proportioning valve but I would like to understand why instead of throwing parts at it.
Thank you

Is it the same symptoms that the prior owner was having before replacing the calipers at the reputable shop and how long ago was that. Does the caliper slide on its pins well? Are they properly lubed?
The previous owner never mentioned any issues or reasoning for the overhaul. Yes the caliper seems to slide fine and cleaned and regreased them for good measure.
I’m leaning towards a hydraulic issue due to how difficult it was to compress the caliper piston. Open the bleeder and it moves back in easily.
That would lean towards a hydraulic issue if it resolves the issue by opening the bleeder screw. Hose collapsing on the same side is a common cause but it sounds like you have done that.. I don’t know if you live in a rusty area and have a damaged metal line to that caliper. As far as I know, the proportion valve issues are pretty rare.
I live in western ny and they’re pretty generous with salt here. That and this car has almost 246,000 miles so I’ll give that a try. I’ll give it a shot this weekend when I have some free time. Thank you and I’ll report back with my results.
you might try and and loosen rubber line from metal line and see if you can push back in caliper with more ease like when you open the bleeder screw. If that doesn’t happen, then look at the rubber line. Next check metal line on other side. Be prepared to bleed system afterwords and if it has ABS, dont get air in there as many need a scan tool to bleed.
