Brodie Brake Booster


BRODIE RESEARCH MAGNESIUM CANTILEVER BRAKE BOOSTER

The Brodie Booster is one of the lightest of the cantilever type booster plates. The Brodie plate is made of magnesium that is cast into the Booster shape. The piece is 6.3mm thick and has 5.1mm wide perimeter walls, both inner and outer. Large openings reduce the weight of the already very light-weight piece.

The total height of the piece is 137mm and at its widest is 124.8mm The inner height of the Booster is 108mm and the inner width between the arms at the bottom is 54.4mm The plate comes with two spacers cast of magnesium that are 17.7mm in diameter and 14.4mm high.

Two 6mm by 1mm steel bolts with a 40mm length, 5mm hex fitting and 9.5 gram weight come with the Booster as well as two aluminum flat washers. The spacers and the plate are electrostaticaly painted (powder painted) fusing a fine colored glossy glass powder smoothly over the outer surface.

The plate weighs 47 grams and the mounting hardware weighs 32.5 grams, bringing the total weight to 79.5 grams. The Brodie Brake Booster is available in Blue, Black, Red or Yellow. Made in Canada.

Since 1995, we have these impossible to obtain. It's not that Brodie is out of business, they haven't established an effective distribution system in the US. Without them available, interest has wained and distributors have been more reluctant to get involved with them. Export according to them is impractical.





In-depth Information About Metals

Aluminum
Aluminum is extracted electrolytically from bauxite ore. It is made by the electrolysis of aluminum oxide which is found in larger concentrations within bauxite ore. Bauxite is a mixture of the hydroxides of aluminum, together with other impurities such as oxides of iron, titanium, and silicon. Bauxite is produced by the weathering and change of aluminum silicate rocks usually found in tropical and semitropical regions where climate has produced an accelerated weathering process. Bauxite is not a rare ore and is widely available in the US, the Caribbean, and Europe. Approximately 4 pounds of read the full article...

Beryllium
Beryllium is a specialty metal that is steel-grey metal in color, with an extremely low density, making it very light weight. At 1.85 grams to the cubic centimeter, its density compares to that of magnesium. It is also a high strength metal, making it possible to design light weight, thin membered parts with ahigh stiffness. A column made of beryllium to support a load placed directly downward on top of it, will have a greater load carrying capacity, and be lower in weight than any other metal of equal size.

Until the 1950's beryllium was used read the full article...

Titanium
The element titanium was discovered in 1763 by an English cleric, William Gregor who was an amateur chemist with an inquiring mind. It was in the black sands of Cornwall that he discovered the new element that had up to that time, attracted little scientific interest. A few years later, an Austrian, Klaproth, extracted the same element from an ore widely known as "rutile", which is a mineral consisting of titanium dioxide (one titanium atom, two oxygen atoms), that is a reddish-brown substance with a slight metallic luster. While rutile is the highest grade read the full article...

Metallurgic Hardness Testing
There are three types of tests used with accuracy by the metals industry,they are the Brinell hardness test, the Rockwell hardness test, and the Vickers hardness test. Hardness is the property of a metal which gives it the ability to resist being permanently deformed (bent, broken, or have its shape changed), when a load is applied. The greater the hardness of the metal, the greater resistance it has to deformation. Since the definitions of metallurgic ultimate strength and hardness are rather similar, it can generally be assumed read the full article...
