New brake pad squeal on one wheel when braking and turning to the left

I recently replaced the front brake pads on my GF’s 2005 Honda CRV. The rotors looked good to me but the old pads were approaching the wear indicator. After replacement I’m getting a squeal while braking and turning left, with maybe a random squeal thrown in when turning right, and nothing while braking straight. Car has 187,000 miles on it.

I’ve been googling looking for something I missed and have come up with maybe a bearing is starting to go or I missed something, with maybe the latter being more likely! Perhaps I should do the rotors anyway and check the bearings? Looking for troubleshooting suggestions! - Thanks!

Sounds odd. was everything put back in place(i.e. parts from the hardware kit like shims, clips etc) Were the floating pins lubed?

You can check the bearings pretty easily.

Jack the wheel up and see if you can shake it back and forth when you grab it at 9 and 3, 10 and 2, and 12 and 6.

Yes though I’m unsure what “floating pins” relates to here. The pins the caliper rides on?

Yes, the small ones with the rubber “accordion” boots.
Perhaps a quick sanding down of the rotor surfaces will get rid of the foreign object that may have gotten lodged on the surface will cure the squeal.
Still odd why the squeal when turning, are the brakes applied while turning?
Bad bearing usually produce a sound generally described by most people as a hum.

What kind of musical tune would be produced if the sounds a car makes could be orchestrated?

Have you ever considered wooden brake pads? I @Know a guy… <ducking and running>

Darn, edited to add that it squeals when Braking and Turning at the same time. Doh!

You leave a few variables out.

The old rotors - if you didn’t “deglaze” them or least scuff them with a scotchbrite pad, then you’ve left the old pad material bedded on the old rotors.

New rotors are $25 each by the way - I just looked them up (that resource may be going away soon tho)

When you installed the pads - did you lube the caliper guide pins ? & the where that pads make contact with the caliper mount? (I am sure few do - but yes you are supposed to)

Bearings - not likely.
If it "shakes at “9 & 3” it is most likely play in a tie rod - that is a steering issue not a bearing.

I might have neglected to lubricate the pins, I can’t recall. I know I lubricated the pad to caliper contact points and the back of the pads that meet the piston. I did not deglaze the rotors or scuff them. I see some various procedures for that online, mostly involving rough sanding.

Planning to take a look today and measure the rotors at the same time. I may PM you on those rotors if that’s OK. Very sad to hear that resource might be going away soon :cry:

Thanks to everyone for taking time to share their insight!

Update: I pulled the tire and realized I did not lube the pins so I cleaned and re-lubricated all parts. dressed the rotor, which looked OK to me but it was not that difficult at the time, and then reassembled. Squeal occurs now very reliably while braking and turning to the left at speeds 10+ MPH, never any other time. Straight braking and braking while turning to the right are A-OK.

I’m stumped. Maybe my hearing is just wrecked and it’s the other wheel :wink:

Jay,

I’m an evening at the Space guy - some evening (after the board meeting tomorrow) works for me.

Contrary to the unnecessary fear - brakes are usually the most basic general repair one can perform to most common vehicles without any issues.
