I have a 2022 hydrid trouring. when backingout of the garage on a damp morning, I get a howling noise from the rear brakes.
I am a retired brake engineer with 40 years of experrience. I know that this is not a functional problem just annoying.
I have asked my dealer about any TSB's but they don't have any.
I know from Facebook posts that this problem is pretty common.
has anyone found a rix for this or heard anything from Honda about it.
I would expect it would involve a different rear lining.

thanks

 

What is a brake engineer? You design brake material?
At any rate, did the dealer look at it? If it squeals when braking have you tried brake grease on them?

 

To answer youor first question I worked for Chrysler Engineering for 40 years designing and developing brake systems for many vehlicesl. Worked on the first 4 whl antinlovck brake system on the 1971 Imperial and many there after.

You can't but grease on brake linings that would really mess them up.
there is nothing for the dealer to look at.
base3d on many comments in the facebook page for Accord hybrids this is a pretty common problem.
There is even an brake engineering term for this "creap-groan" I know that the problem is because of the damp ness at the first stop in the morning.
Since the dealer service people where no help I was asking if anyone had found a solution. given how common the problem is I have to assume that Honda Engineering knows about it.

 

You are an engineer? You grease the pins and slides not the friction material. You engineers should work on the stuff you design.
