December 16, 2018 at 9:58 am in reply to: Accord 2010 Rear brake caliper won’t compress during pad change #891838
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.
Holger: Yes, I have P0420 code.
Civvy: Other than code…. just the miles on the car. I am preparing for worst case… but, agree I need better diagnostics.
Dtidman: I will check out those ETCG & Scannerdanner references. Rust: Agree… as a 1970’s kid I became rusty bolt knowledgeable restoring 1930 Model-A. Fire protection: YES… Very good advice. I wouldn’t use a torch inside my attached garage. We should all be fanatical with safety & fire protection.Thank you, all!

Attachments:This problem is resolved! It turns out that it was the “backing plate” or “splash guard” rubbing against a rusty rotor edge… only heard during hard turn under load.
.
I disassembled the brakes and removed the rotor to do a careful inspection. I noticed a 3/4 inch curved clean scratch at the rotor diameter (see image bottom). I bent out the backing plate a bit, filed off the rotor edge rust and re-assembled…. noise gone.A couple weeks ago I had carefully examined the wheel bearing play with tires lifted.. then, removed… rotating wheel and turning the steering. The front bearings did seem fine. So, I re-read all the ETCG advice here.. decided to look for rubbing with rotor removed.
I was really gearing up for a wheel bearing or CV replacement. I watched Eric’s video multiple times… was pretty sure I could find an “XD-45…” tool look-alike.
The brakes are still pretty meaty.. I had replaced them two years back. I NOW believe the backing plate was probably slightly deformed by the excessive snowfall I bounced thru up here in northern NJ this winter.
Thank you ETCG team: cam0888, Fopeano, Koinonia. Your ideas shaped my thinking for a $0.00 cost solution.
Koinonia, when I say hard I mean like a sharp right turn in a parking garage. I know what you mean with power steering stop. It definitely is a rotation sound. I did look for abrasions and scoring but didn’t find them. My chief suspect is bearings, cv joint.
Thank you!My a/c problem was resolved!! Faulty compressor relay. It was failing intermittently, so it fooled me for a while. An $8 part. I love it when a/c problems are fixed for $8. I appreciate all the suggestions… that got me started.

My Commute is from Hackensack: Exit 16(or 18) to 9, New Brunswick.
I fired up the Honda…. all venting(including recirc) was functioning. The a/c worked also.
Typically, difficult to troubleshoot an intermittent problem. I almost wished it was broken when I checked it! On your advice I looked into the AIR CONDITIONER (A/C) SENSOR p/n: 80530-TA0-A01 ; Now, I need to find a service manual related to it. I really believe it’s a sensor or switch or wire connection. But, cars have proved me a cheap dope before.My Commute is from Hackensack: Exit 16(or 18) to 9, New Brunswick.

I think so. I’ll check. I’ll review venting effects more scientifically. All this was going on while on the NJ Turnpike! If they function properly… I will look into an evap air temp sensor. Good lead. Thanks. Either way… I’ll report back.College Man,
