Which type of brakes are commonly used in trucks?

Semi trucks often use compression brakes. When activated compression brakes open valves in the engine, slowing down the engine and bringing the truck to a stop. Non-semi trucks use disc brakes to stop. A common type of brake system used in big trucks is the air operated "S" cam.

No. Drum brakes are large and contain the mechanism within them. Disc brakes are slim and use calipers to slow them down. Although both are very similar, disc brakes are more advanced and a better option for your car.

What is the braking effect system on a truck?

Depending on what the truck is, it may have air brakes, air-over-hydraulic brakes, or hydraulic brakes. Air brakes may be foundation brakes, to include flat cams (very rarely seen), S-cams (the most common), or wedge brakes (not so common anymore, although they are sometimes used on the steer axles of heavy haulers and vocational trucks), or they might be disc brakes, or now, even piston brakes (as far as I know, UPS is the only major carrier which uses them). Depending on country, truck brakes will either use ABS (in N. America) or EBS (in Europe).

Disc brakes are more powerful, but it's easier to add a parking brake to a drum brake. So the front wheels often gets disc brakes, as they do most of the braking anyway, and the rears get drum brakes.


Which wheels would the wheel cylinders be on if a vehicle has front disc brakes and rear drum brakes?

The wheel cylinders will be associated with the rear drum brakes. Drum brakes use a wheel cylinder to activate the brakes - push the shoes out against the drum. Disc brakes use a caliper unit to push a piston out and squish the brake pads against the rotor. The front disc brake pads are pressed against the rotor by pistons inside the calipers to slow the vehicle. Both are hydraulically controlled.
