ANNOYING Brake/Caliper Squeal
Hey guys, I've searched already i see that this topic has been covered a few times but no one's seemed to have my same issue:

Here goes.....my right FRONT passenger side brake is squealing like hell now. I originally thought it was the hub assembly and ordered one (now I have to send it back), and I noticed that wasn't the problem because the noise was coming from the brake and/or caliper. Now while searching, I've seen it could either be brake dust, worn pads, or the caliper sticking. It just sounds as if a nice little lube (#pause) or some WD-40 would do the trick. When I brake, it squeals and when I let off the brake...it squeals for about 2 more seconds then fades. I also hear it slightly when I turn to the left. I just want to know if I need completely new brakes or rotors or if its a simple fix as lubing it somehow and then the problem goes away. If anyone could help, I'd greatly appreciate it because as someone else had said...this is completely annoying and embarrassing. Thanks in advance for your help.

 

Feel the rotors if there's warpage get them resurfaced uneven friction between the rotor and pad may cause loud whistle/squeak. I have done extensive research on this topic and found out that squeak is primarily always caused by vibrations with pads over the rotor the only way to fix this is with high quality lube the can resist temps up to 2000 degrees. This lube should be applied to the back of the pads and let dry to the touch before re-installation back onto the calipers.

The lube should absorb any and all vibrations during braking and should remove that squeak, I recommend copper slip lube.

Hope this helps!

 

I have to remove the brake to feel the rotors, correct? I tried doing this today when I was going to change out my hub assembly but the two 22mm bolts were on there tighter than a b**** so I couldn't get the brake off. To apply the lube, the brakes must be completely removed or can it spray in there to let it settle?

-Thanks

 

Do you put the lube where the pads make contact with the pistons?

 

have you try to lift the front end and spin the wheel to figure out where it comes from?

 

Yes exactly apply a layer evenly on the back of the pad let it dry then simply reinstall the piston, if there's any rust build-up on the anti rattle clips and shims make sure to clean that off with some brake cleaner first, after cleaning those parts apply just a bit of lube on those then re-insert them back in there place.

You should be set oh an to answer the op you do not have to remove the brakes or for that matter the rim to feel any warpage on the rotor. Warpage happens pretty evenly across the rotor so you should be able to feel it on any spot of the surface area.

 

Yea I did. Originally, I thought it was the hub assembly so I ordered one and went to try and put it on, so when I took the tire off and lifted it, I spun it to see if I could hear the noise and it came from the brake area and not the bearing/hub.

I would try lubing the brakes myself but I can't get the two bolts off for the life of me.

 

G-Spot, sounds like you got your answer. You don't need to have your rotors resurfaced since you didn't mention vibration in the steering wheel when applying the brakes. That's the indication they're warped. You need brake cleaner and pad lube, available at most auto parts stores. G/L

Sounds good, thanks again for all your answers and replies

 

Make sure that the spring clips are installed correctly, otherwise, the pads will rub against the rotors all the time.
