W177 Rear Wheel 355x12mm Drilled Brake Disc Brake Bracket Center Hat

Product Description

W177 Rear Wheel 355x12mm Disc Center Hat Caliper Holder Bracket

Disc brake construction

The brake rotor (disc) which rotates with the wheel, is clamped by brake pads (friction material) fitted to the caliper from both sides with pressure from the piston(s) (pressure mechanism) and decelerates the disc rotation, thereby slowing down and stopping the

How disc brakes work

When the driver steps on the brake pedal, the power is amplified by the brake booster (servo system) and changed into a hydraulic pressure (oil-pressure) by the master cylinder. The pressure reaches the brakes on the wheels via tubing filled with brake oil (brake fluid). The delivered pressure pushes the pistons on the brakes of the four wheels. The pistons in turn press the brake pads, which are friction material, against the brake rotors which rotate with the wheels. The pads clamp on the rotors from both sides and decelerate the wheels, thereby slowing down and stopping the vehicle.

Main components of disc brakes

Main components of floating type disc brakes
There are two types of disc brakes. One is called the "opposed piston type disc brake" which has pistons on both sides of the disc rotor, and the other is the "floating type disc brake" which has a piston on only one side. The floating type disc brakes are also called the sliding pin type disc brakes.

Center Hat

Jekit has four different designs.
1. Pattern: unique nest fan diversion design, reducing weight by 35% and increasing heat dissipation area by 30%.
2. Original: round design, light weight.
3. With drum joint: generally applicable to the rear wheel of automobile.
4. Floating style, floating design, lighter weight, 50% increase in heat dissipation area, effectively improve heat dissipation effect and reduce jitter.

Product introduction

The center cap and caliper bracket are the components connecting the modified caliper to the vehicle. Each set of center cap and caliper bracket is customized according to the model, caliper model and disc data. Therefore, if you want the whole set of brakes to be perfectly installed in the wheel, the data requirements for the center cap and caliper support need to be very accurate.

Material classification (center hat and bracket )

Jekit's center cap and caliper support are mainly made of the following materials: aluminum alloy 6061-T6, aluminum alloy t-7075 and 45 steel.

Aluminum alloy has the characteristics of high strength, light weight and good heat dissipation. For the braking system, aluminum alloy has great advantages, so aluminum alloy is used in most cases.
6061-T6: aluminum alloy element accounts for 97.9%, magnesium element accounts for 1%, silicon element accounts for 0.6%, and 0.28% copper and 0.2% chromium are added.
T-7075: the main aluminum and zinc metal elements account for 90% and 5.6% respectively, while magnesium accounts for 2.5%, copper accounts for 1.6%, chromium accounts for 0.23%, and finally the rest are silicon, manganese, titanium and other metal elements.
Generally speaking, the strength of 7075 aluminum alloy is higher than that of 6061 aluminum alloy, which is mainly because the content of aluminum alloy in 7075 aluminum alloy is nearly 8% less than that in 6061.
45 steel is generally applied to supports with limited data. (for example, there are few threads and the length is short. The whole strength needs to be guaranteed, which can not be achieved by aluminum alloy)
