Why do the rear brakes of pickup trucks use drum brakes?
Because of its reliability and powerful braking force, drum brakes are still available on many models (mostly in the rear wheels).Brake drum brake cost than the high cost, and because the rear wheel in the daily running and not braking, so this is a compromise of a cost function.The drum brake is pushed by the hydraulic device to brake the brake disc inside the brake drum to make the brake pad friction with the inner surface of the brake drum rotating with the wheel.
Because the pickup truck is driven by the rear wheel, there is a lot to add to the plate brake. That's the price of the factory.
The engine of the general car is front, and the front and rear weight of the car is generally 6:4. The front and rear drive may reach 5:5, and the normal start speed may be 5:5. When the brakes are braked, the weight will rise and the weight ratio may reach 7:3 or higher 8:2, so the front wheel brake effect is better, and the rear drum brake plays an icing on the cake.
Brake cooling, thermal recession, good braking effect
Drum brake sealing is good, suitable for suburban, off-road, brake drum brake disc is better than static.
