brake pad compounds

[quadracer12]

Hi all,

I am looking into getting brake pads made for MGB and other british cars. The issue is that companies that give me quotes do not specify the compounds they use. What i am wondering is if anybody knows the compounds or materials used in "old school" organic brake pads, which make very little noise?

Information on modern brake pads would be extremely helpful as well, because the plan is to offer upgraded pads (semi-metallic and ceramic).

Thanks in advance!

Perform an Internet search for ORNL/TM-2001/64 Compositions, Functions, and Testing of Friction Brake Materials and Their Additives. This is a report from Oak Ridge National Laboratory dated September 2001, and is a good review and introduction to the subject.

The most obvious change in pad compounds over the last 30 years is the removal of asbestos from the formulation.

There are various attempts to replace the asbestos with materials that do not present such a health hazard.

I've found that one of the best sources for this type of information is the patent literature. Many patents contain detailed tutorials of prior art to justify the invention as new. Friction materials are witches brew.

Yes, traditionally they include everything but the kitchen sink- semimetallic or ceramic pads include that too!
