Alston proportioning valve. Tempilaq temperature-sensing paint from Big-Three Industries. Introduction 11 Basics Suppliers List. THANKS brake suppliers and Thanks to the many brake and experts experts who helped helped with technical information and photographs.
Thanks also to Carroll Smith of Carroll Carroll Smith Carroll Smith Consulting for helpful helpful suggestions given given after reading reading the finished manuscript.
His His heroic efforts and and great technical knowledge gained gained over the years as a Ford Ford Motor brake-design engineer and and race-car brake-design consultant made made a significant contribution to the content and completeness of this book.
It could could not have been been this quality without him. Thanks Garrett. All recommendations on parts and procedures procedures are made without any guaranteeson guarantees on the part of the author or HPBooks.
