2012 Honda Accord - Rear Brake Caliper and Wheel Bearing

[maverickfhs]

Trying to replace rear brake pads and rotors:

1- No matter what I do, pistons are not moving, tried to crack 10mm brake bleeder some fluid came out but caliper is not budging.

2- One of the rear wheel bearing needs replacement, any help and inputs for both issues? Thank you.

Sounds alot like a seized caliper. Had something similar on my 09 Accord and ended up buying rebuilt calipers.

Napa calipers are my go to on my Honda, better hardware and they are coated so no rust like the other parts stores. Also do the flex hoses while you are there. I don’t have any experience with wheel bearings but I believe South Main Auto might have a video on one.

Are you turning the piston or just trying to compress it?

Those are parking brake in caliper, calipers. The piston has to be rotated to compress back in.

 

[The Critic]

Piston needs to be compressed AND rotated at the same time. They can sometimes require a lot of force.

Need this tool:

Turning the piston clockwise, left side has moved and is almost there, but right is not budging at all - dust seal has a small rip in it too.

That is exactly what I am using but having no luck with one side.

1- Are you rotating the piston with the proper caliper tool to retract it? See the video below at ~3 minute, 30 second mark.


2-See video below to replace the rear wheel bearing. It is a piece of cake.

Then unless it's bottomed out, it's seized.

I sometimes have to use a 1.5 ft long ratchet to get it moving.

It is protruding and that side rotor and pads were chewed up quite bad vs the other side where caliper at least was pushed back with bit of force.

How do you hold it in place? Because we tried to use a lot of brute force but place is tight and caliper is not budging.

Might be able to take the rotor off, mount the caliper back on there and use the car to hold it.

Do you use the parking brake?

The good news is that they make all-new calipers for your 2012 Accord, so you don't have to put up with poorly "rebuilt" garbage.

These kinds of calipers are prone to failure, especially when you don't use the parking brake.

Yes, use the parking brake but not the original owner so no history

Any recommendations for the new caliper? Thanks

Yep, my Accord has them, but the TL (Same platform) has the parking brakes in the rotors.....not sure which is worse. I'm not pulling the rear rotors off the Acura until they refuse to work any longer. I hate drum brakes, and miniature drum brakes have to be even worse.

Changed my mind. The TL is worse. I'd rather replace 50 calipers than tear down a mini set of drum brakes.

Raybestos has been making them the longest, so I'd be inclined to use those. I see that DFC is starting to offer new calipers, too. They might also be worth trying.

Honestly, those drum-in-disc parking brakes actually aren't that bad. You basically never have to actually do any kind of service or touch those parking brake shoes at all

The only time you encounter difficulty replacing the rear rotors is if you left the parking brake on.

The best parking rake setup is found in older GM RWD cars with 4-wheel discs. In those, the parking brake shoes are a 1-piece horseshoe shape that just pops off and back on, with no scary springs at all

I have had to put some on a vise.

I was planning to use vice grips and then see how it goes, would it be worth trying or just go ahead and replace the caliper? Thx

Maybe just replace the caliper.
