improper adjustment causes overheating transmission and engine, diminished power, and—in the case of cotton linings—rapid destruction of the band lining. Wooden - Wooden linings were originally offered as a "longer life" accessory part during the life of the Model T. They are a single piece of steam bent hickory fitted to the normal Model T Transmission band and experience has shown them to have a long life, often more than the original style cotton linings. These bands give a very different feel to the pedals, with much more of a "bite" feel. The sensation is of a definite "grip" of the drum and seems to noticeably increase the feel, in particular of the brake drum. Kevlar - Kevlar linings often create a fair amount of discussion. They are a modern alternative lining with Kevlar fibers woven into a polyester band lining. Kevlar bands have been reported to have an extremely long life span, even under adverse usage conditions. It seems that they generally need to be more carefully bedded in and require frequent small adjustments in the initial run in stage, but after this, require little to no adjustment for very high mileages. Because of the nature of the fibers, they have a very high melting point and can therefore stand a lot of slipping and heat, however, the heat tolerance of Kevlar is much higher than that of the actual drum that it is clamping. Model T Ford drums are prone to cracking, and high levels of heat exacerbate
