  Disk brake assembly - Patent 4742895
A disk brake in which the brake is assembled with the thickness of the available wear portions of a first group of disks being different from the thickness of the available wear portions of a second group of disks.
By maintaining disks of different thicknesses of the available wear portions, the piston travel is reduced and the size and weight of the brake may be reduced while at the same time the heat sink mass of the worn disks is not reduced excessively and worn brake operating temperatures are lowered.
The wheel and brake assembly 10 is of a type used for an aircraft and may have a prior art disk brake 16 positioned between the rim 12 and a stationary axle 18.

 Automobile Brakes - A Short Course on How They Work
The typical brake system consists of disk brakes in front and either disk or drum brakes in the rear connected by a system of tubes and hoses that link the brake at each wheel to the master cylinder.
With drum brakes, fluid is forced into the wheel cylinder which pushes the brake shoes out so that the friction linings are pressed against the drum which is attached to the wheel, causing the wheel to stop.
Disk brakes wear longer, are less affected by water, are self adjusting, self cleaning, less prone to grabbing or pulling and stop better than any other system around.

 CHRIS' TANDEM TIPS: Disk-brake FAQ
A disk brake consists of a rotor (the 'disk'), which is mounted to the hub, and the brake caliper, which mounts to the frame.
A drag brake is a brake which is switched on at the beginning of a descent to slow down the vehicle constantly.
Mechanical disk brakes' biggest advantage used to be their low price, but since the advent of the Magura Julie hydraulic brake, which is sold for DM 199 (less than US$ 100) in Germany, that advantage is gone, too.

 CITROËN - Disk brake
When the driver brakes, the pressurised liquid in the accumulator is sent to the mobile calliper, which has two jaws fitted with pads.
The liquid moves a piston, which brings the mobile pad into contact with the disc and causes the calliper to bring the second pad into braking contact on the disc.
Braking pressure is balanced automatically and is uniform across the entire friction surface of the pads.

 Disk brake and Quick Release problem
The first basic problem of a disk brake is that the position of the disk calliper means that the frictional force of the brake pads on the disk acts largely to push the wheel downwards, broadly in the direction of the open fork ends.
The force that the pads exert on the disk is very large - much much greater than the force from a rim brake (due to the smaller diameter of a disk compared to wheel rim) and it is also at an inappropriate angle.
The radii of the disk and wheel are r1 and r2, and finally the angle of the dropout exit is 'a' in front of vertical.

 HOME-BUILT DISK BRAKE
To take the high torque of the disk brake, the spokes on that side are crossed four times (note that in the pictures shown on this page the spokes are laced with only a single crossing, but this was later changed to 4x and thinner spokes were used).
With the disk, adapter plate and enough space for the brake caliper, the fork had to be made wider than a normal front wheel requires.
A standard brake cable is attached at the top end of the lever connecting it to a conventional brake lever on the handlebars.

 Pirate4x4.Com - Product Review Toyota P/U & 4runner Rear Disk Brake Brackets
Probably one of the biggest advantages of any rear disk brake setup is elimination of the problematic stock rear drums in wet, dirty, or muddy conditions.
If the brakes are just not as good as you want them, you may need to upgrade to a larger master cylinder, add a residual valve, or possibly adjust (or remove entirely) the rear brake proportioning system.

  Brakes - Partstrain.com
On a disk brake located in front of your vehicle, fluid from the master cylinder is compelled into a caliper where it presses against a piston.
Whereas the brakes that can be found at the rear of your vehicle or drum brakes, fluid is forced into the wheel cylinder that drives the brake shoes out in order for the friction linings to be pressed against the drum connected to the wheel which then causes the wheel to stop.
In either case, the friction surfaces of the brake pads on a disk brake system or the shoes on a drum brake convert the forward motion of the vehicle to heat.

 History of the Disk Brake:
Another important development occurred in the 1920’s when drum brakes were used at all four wheels instead of a single brake to halt only the back axle and wheels such as on the Ford model T. The disk brake was again utilized during World War II in the landing gear of aircraft.
Early disk brake systems required an outside mechanical brake booster such as a vacuum assist or hydraulic pump to generate the pressure for primitive friction materials to apply the necessary braking force.
The conventional disk brake, on the other hand, consists essentially of a flat disk on either side of which are friction pads; equal and opposite forces may be applied to these pads to press their working surfaces into contact with the braking path of the disks.

 Ogura Industrial Corp. - Industrial Products - How They Work - Hysteresis Permanent Magnet Clutch or Brake
Function: Most units contain a hysteresis disk, which is directly attached to the hub that passes through the clutch/brake.
The opposing circular magnets set up magnetic flux, which causes drag on the hysteresis disk, which in turn, causes drag to the hollow hub in the unit.
As the poles are changed from a north to south alignment, the flux passes directly through the hysteresis material, reducing the amount of drag on the hollow hub of the unit.
