front disc squeal?

[JohnRod]

the left front makes noise, from a slow stop. but not always. also it did this before I changed pads [which was a long time back.]
ideas?
thanks Rod in AZ

Sticky caliper?

Low quality pads? Wheel bearing? Yard sprinkler that only waters front left wheel? At least the unpleasant noise is not coming from the passenger seat. Passenger seat noises are usually difficult and costly to fix.

Jack up that wheel, spin it by hand, feel it and listen to it, compare it to the other side.

Brake squeal can be from loose pads, usually the outer where the ears aren't tight enough. If the landings for the inner pad are wallowing out, it can allow the inner to move excessively too.

That pad backing anti squeal goop will help too, but if the pads are allowed to move, even that goop will fail in short order.

That has been an issue with brakes since the dawn of cars.

Actually, brakes always make noise. Trick is for them to make the noise out of the range of humans. That being said, there are several ways to mitigate it. Notice I said mitigate not eliminate.

As suggested type of lining, lubrication, rotor finish/thickness, and a myriad of other things will affect it. What I do is sand the pads and rotors or if lathe is available us that, clean slides if needed and apply high temp caliper grease to the BACK of the pads on both sides, remove and grease pins, pinch down pads where they attach to the caliper. Also, harder pad material is more prone to noise, try a softer and usually cheaper pad.

There is no magic bullet for stopping the noise.

Heavy metal and turn the radio up. Noise just disappears. Lol.

I put those brembo brake pads on my work van and they bloody things squealed from day one. Drove me nuts. Tried all sorts of stuff but never worked. Only thing that fixed it was buying a new van.

This works if used correctly. Need to spray the pads the day before you plan to install them. If you just spray the pads and install immediately, all the sticky, just squeezes out.

And it goes without saying, don't put it on the rotors

Yes, you coat the backs of the pads so they stick to the caliper and the piston.

Turn the stereo up.

I've found that dust and dirt is the most common cause of brake squeal for my vehicles. Pull the tire/rim assembly and do a visual, check for rocks stuck in the caliper rubbing on the rotor.
I guess I'm just up the road from you in Dolan Springs. Welcome

Make sure the brake backing plate is not bent anywhere that it might contact the back of the rotor,also make sure no gravel or other debris is between the backing plate and the rotor.Another trick if yoi think it is rotor finish use a scotchbright disc on a right angle die grinder to put a mon directional swirl on the rotor,front and back.

Have found carbon ceramic pads are less prone to noise. Did install a set on an older Maxima. The noise came and went, mostly went. Don't think CC pads are recommended for HD use.
