94 E420 Front Brake Squeal / ABS

I've been doing my own work on my cars (Mercedes and Volvo) for about 15 years now and have finally been stumped by what is usually a trivial issue.

I've replaced the front rotors (Balo) and pads (Textar from dealer) and used the dealer-supplied brake paste but I CANNOT keep these darn things from squealing! Furthermore, when I almost reach a complete stop, about 10% of the time I'll get the ABS activated, which is un-nerving. The ABS light has never come on, so I don't suspect an ABS fault. The tires (Michelin MXV4)have a decent amount of tread left, and this happens in both wet and dry conditions. WTF???

The pads on this car are from the dealer and are the type that come with two aluminum shims (ostensibly to address squealing). I've put a liberal amount of MB brake paste on the back of each pad, but to no avail.

Any suggestions? I'm thinking of pulling the pads again and putting paste between the back of the pad and the first shim, then more between the two shims and then slather even more on the back of the shim that is in contact with the caliper piston. The pads come out of the box with a small amount of paste between the pad and the first shim.

I'm at my wits' end on this. I need to sell this car before winter hits and the squealing and ABS are driving me nuts (a short drive most days )

Thanks!

Texstar Pads too Hard

My SAAB 9000CSE came standard with Texstar pads and ATE rotors. They were great, and lasted over 50K even in New York/Long Island stop and go. But they create nasty dust and, due to their hardness, they wear the rotors.

I am not familiar with the brand of rotor you mentioned. I have had good luck with Brembo, Zimmermann and ATE rotors. You could also try a softer pad like the PBR organic. It will wear faster, but it may not conflict as much with the rotor. I have used these Austrailian-made pads for a few years on various cars and I have never experienced brake squeal or excessive dust. But they don't last even a third as long as semi-metallic pads like the Texstar.

The PBR is a reasonable suggestion. We don't use them anymore cause they are crudely made, but the material is definitely good at stopping squeeks.

The ABS function is undoubtably a poor or dirty wheel speed sensor. When the event takes place above 10kph you will get a light.
