New Bendix Brake Pad Noise

[Rock_Hudstone]

I just replaced the front brake pads on My 2000 Dodge Caravan and now there is some pad squeal now and then. Especially when heated up from local driving, very embarassing stopping at intersections.

The pads are the older style Titanium Metallic bonded/rivited design without chamfers or cuts. However, I've use these pads on many vehicles over the years without so much as a sqeak??

Did you put some anti squeek on the back of them? I use the stuff in an Orange bottle.

Those do tend to be noisy pads. I've had them make squeaky noises, grindy noises, and just once I got a set that made a "bwip!" noise. Use the usual tricks and it may help. Then again it may not. You'll find out after you do it.

Call back in another 1k miles.

No, I don't grease the backing plates, never had to, and I believe the best practices trend is away from that these days. Probably attracts dirt and grim as well.

I should mention the rotors are used but within service specs.

Bah! Yer so-called grim dert won't find it's way anywhere what matters!

Yeah, I think I'll let it go a while, then if still noisy apply a small amount of moly lube to the outer pads.

I noticed they don't fit tightly as on GM vehicles.

I'd still butter the brake pads(back plate) with caliper/pad lube on the back of the new pads. It will help absorb some more of the noise. I always lube the sliders and back of the pads with Permatex Silicone Brake Lube(for sliders/pads). Just to eliminate the noise in the first place.

But, you may also have some rust on the rotor(s) somewhere that you may not have seen, causing some noise/squeel. Not that you needed rotors but, did you replace the rotors too?

Yeah I know, I agree that you can install many sets of pads for many years without having any noise(s) but, this is that set of pads that are causing you some grief in terms of squeel.

That is probably your problem. Semi-metallic pads are quite sensitive to the rotor condition, and the failure to resurface or replace the rotors is contributing to your noise problem.

Also, you should remove the caliper bracket and remove the clips that the pads sit on. Take a file or wire brush and clean any rust off of that area and on both sides of the clips. This will also reduce noise.

I cleaned everything throughly; rotors, calipers, brackets etc, spent a lot of time on that in fact. I also carefully measured the clearance for the proper shim clip size.

They were noisy today, again after heating up. I'll try the easy stuff first, lube of the back of pads, then perhaps chamfer the edges.

Great, keep us posted

did you burnish the pads?

Lots of good info here too.

Negative on the burnish.

Interesting, today was a sleet/rain mix and not peep from the pads. Past week or so the weather has been very cold and dry.

Also occured to me, I forgot to check the position of the wear sensors during the install, not sure if they should be on the leading or trailing edge of the rotor in this application.

Thanks for the link. Here is another good brake/front end site I came across:

A fine pad we have used before. Not normally much of a squealer.

As long as I was certain everything else is good I would not hesitate to bed the brakes thoroughly. It works great for me...

Update: Brake noise disappeared after a few hundred miles on the pads.
