Hi,

I've finally got my new brakes to stop squealing.

I replaced everything, new Brembo rotors with bearings and seals, Rebuilt Calipers, ATE Brake Pads. I did some front end work 1st replacing the top ball joint and the tie-rod ends.

You think with all that I would have minimal brake noise but no, I was a screaming 83 Vanagon going down the road.

I started by checking the rotor bearing axle nut, 1 seemed too loose so I tightened it just a little so the rotor didn't have any play and re-peaned the nut.

Then I got a brake pad lubricant as described in many reviews; Brake Pads Silicone Lubricant - ATE 70015. This was applied to all areas where the metal contacted other metal parts but mostly between the brake shim and the brake pad.

Lastly I found a reference to chamfering the brake pad edges. The ATE brand does not factory chamfer its pads. I put a 1/4" 45 degree bevel on the leading edges of the pads with my bench grinder.

Sadly I found later that the Bosch QuietCast has a special rubber shims and is also factory chamfered. In hindsight this would have been my 1st choice.

Still with these all these improvements all of my brake noise is gone.
I wanted to share so you can benefit from my search.

and sometimes just using them for a hundred miles will clean off any dust or dirt and that cures the squeal

NAPA has so orange rubber shit that you can coat both sides of the pad shim with- it works sometimes.

Scuffing upper the face of the new rotors with some 80 on a DA prior to installation will allow the pads to seat faster without the squeaking.

Half a dozen hard stops from 55mph can shake out the squeaks.
Gotta get through the glaze & seat those new pads to the rotors...
