The safety standards for brake disc thickness are as follows: Mechanical performance requirements: Tensile strength >=206MPa, bending strength >=1000MPa, deflection >=5.1mm, hardness should be between 187~241HBS. Additional information: 1. Brake disc classification: (1) Structurally, there are solid brake discs and ventilated discs. Solid brake discs are simply metal discs used for braking without any special construction. Ventilated discs come in two forms: slotted discs and drilled discs. Both treatments aim to improve the cooling performance of the brake disc, reduce thermal fade, and provide better braking capability. (2) By material, they are divided into carbon fiber ceramic brake discs and metal brake discs. 2. Brake disc selection: First, check whether the replacement brake disc is a genuine part, the integrity of the product packaging, whether the anti-counterfeiting marks and packaging labels match those on the brake disc, and whether the product model matches the content of the certificate. Brake discs produced by regular manufacturers have clearer packaging prints, including license numbers and execution standards, while the packaging box contains a certificate of conformity, production batch number, production date, etc.

What Causes Heavy Steering Wheel in Cars?

Car steering wheel heaviness can be caused by: 1. Insufficient tire pressure; 2. Replacement with different tire models; 3. Damaged or poorly sealed dust boots; 4. Dirty, insufficient, or air-contaminated power steering fluid; 5. Uncalibrated torque sensor; 6. Deformed front wheel suspension or abnormal wheel alignment; 7. Stuck steering column. The steering wheel is connected to the steering shaft via splines, converting the driver's force applied to the wheel's edge into torque transmitted to the steering shaft. Methods to lighten car steering: 1. Start the engine and engage gear, wait 3 seconds; 2. Turn steering wheel fully left/right, wait 3 seconds, then return to center and turn off engine.
