Did your brake pads delaminate? Tell us about it.

We encourage our NRS Shop Talk readers to share with us their stories about brake problems they might have experienced. We are especially interested in complete or partial brake pad delamination where friction separated from the backing plate.

POSTED BY BikerBill on Do It Yourself forum

For reasons I don’t understand the brake pads delaminate on my Audi A4 after several years use. It happened to the OEM pads and now the replacement Mintex Red Box pads are doing the same thing. The friction material separates from the steel back plate. The friction pad is captive within the caliper cage so the brakes still function, but if you brake going backwards and then brake going forward you can hear a clunk/click as the friction pad moves back and forth and hits against the caliper cage.

I probably have 6 or 7 mm of friction material remaining. So I’m wondering if I can just re-cement the friction material to the metal backer plate again. When I looked at the OEM pads after this happened before it appeared that the original adhesive didn’t fail. Rather, some of the friction material tore out of the body of the friction pad, so I was left with a few divots pulled out of the friction pad (and matching bumps of friction material on the steel back plate).

Does anyone know what kind of structural adhesives are used in brake pads and if it’s available on the open market? Obviously it needs to have high shear strength and good temperature handling capability. I figure if I try this and it fails I’m no worse off than I am right now. The friction pad will still be captive in the caliper cage and I’ll hear the clunk again when braking after changing directions. Then I’ll know my little experiment failed and I’ll have to buy new brake pads. I don’t see much risk in trying this.

Has anyone tried this? How did it work? What adhesive did you use?

NRS Addresses Growing Concern Over Automobile Brake Safety

Brake safety a driving force in the development of NRS disc brake plates

Toronto, ON, February 4, 2010 -- Leading brake technology developer and manufacturer NUCAP Industries Inc. says its NRS plate technology was developed to address many safety concerns with automotive brake pad technology.

“The brake pad/disc brake interface is a violent place, with severe friction, vibration and extreme temperature fluctuations”, says Gerry Roy, NUCAP’s Vice President of Product Development. “Prior to the Integrally Molded system, disc brake pads were fastened to the steel backing plates with rivets which provided a mechanical attachment. Due to many performance demands rivets were fazed out and replaced with glue, which acts as the main attachment component in brake pad assembly. Glue will break down when subjected to high heat conditions experienced in harsh braking conditions."

NRS is a mechanical attachment method that secures the friction material to the steel backing plate and eliminates the risk associated with glue. There is a need for a regulatory body that determines the proper components that make up the complete disc brake pad.

From its first introduction to the marketplace, NUCAP’s NRS proved popular with manufacturers on selected applications of Original Equipment pads, racing applications and aftermarket brake pads. NRS will provide the safest attachment method available in the industry.

Original Equipment Integration of NRS Expands Across North America

More Vehicle Manufactures in North America are using NRS as their disc brake foundation in an increasing number of vehicles and platforms than ever before, and on platforms that represent North America's biggest sellers - Light Trucks and SUVs.

With consumers demanding that these platforms stand up to heavy payloads and extreme use - and provide car-like on road performance at the same time - car designers are raising the bar in what today's brakes need to deliver.

To achieve this combination of truck toughness and luxury car performance, a growing number of OE development teams have turned to NRS as their foundation layer. This growth includes NRS MAXX, NUCAP's solid plate version of NRS.

This use of NRS within OE adds to the expanding use of NRS across the entire industry. NRS is rapidly becoming a global standard for mechanical attachment in racing, special vehicle applications, premium ceramic, air disk, and more.

A Continuous Process of Innovation

Our success with NRS is the result of NUCAP’s ongoing commitment to the development of new product and new innovations. Our goal remains technical leadership within our market, and we continue to develop new solutions. Our results make NUCAP the first stop for Systems and Friction Companies looking for innovation and efficiency.

With our expansion into the design and manufacture of shims and hardware for Disc Brake Backing Plates, our innovative focus has expanded into new territory, and we have launched new products, including NRS MAXX, NRS XL, NU-LOK ShimsTM, Piston Cushion and more.

O.E. Adoption of NRS In North America Accelerates

While initial use of NRS in O.E. was limited to solutions for O.E./O.E.S. programs dealing with delamination issues, testing demonstrated the virtues of NRS in both end-use performance, and in bringing efficiencies to friction manufacturing.

NRS Leads NUCAP into the Global Marketplace

In the first 18 months of its introduction to the industry, NRS achieved a staggering level of implementation for a new brake system technology – 30,000,000 Units. Now, the combination of global licensing and adoption of NRS into North American and Japanese O.E. Programs is pushing NRS to Global Solution status.

NRS Manufacturing Licensed to Manufacturers in Europe and Japan

Global demand for NRS has added a new dimension to NUCAP – Technology Licensing. The completion of NRS Manufacturing Licensing Agreements with SERA Company Ltd. of Japan and Obtec A/S of Denmark, allows European and Asian Brake Friction and System Manufacturers access to “local” NRS production sites.

Within these markets, NRS is in the process of adoption into a broader range of programs. For Obtec in particular, program conversion has been rapid, with over 80% of the products manufactured now utilizing NRS.
