Abnormal noise when braking may be caused by the following reasons: Foreign objects between brake discs: When driving through muddy, dusty, or gravel-filled complex road sections, it's inevitable for foreign objects like sand to enter between the brake pads and brake discs. When foreign objects are present between them, operation will certainly be affected to some extent, and the friction of sand during braking can easily produce abnormal noise. Uneven wear of brake discs and pads: Brake discs and pads naturally experience wear, but over time, uneven wear may occur. One side may be excessively worn, while the other side may develop edges. When the thickness on both sides is inconsistent, abnormal noise will occur. You can choose to grind them evenly with a grinder or replace the brake discs and pads.

Is Adding a Front Splitter to a Car Considered Illegal?

Adding a front splitter to a car is not considered illegal, but it requires filing with the public security authority management department. If not filed, it may be deemed as illegal modification, and depending on the circumstances, it may also require changing the driving license for filing. Regulations on car modifications: 1. If the front splitter is installed without passing the modification approval process, traffic police may impose corresponding penalties. Installing a front splitter is a decorative modification, and as long as it is registered with the vehicle management office, it is not considered illegal modification. Illegal modifications mainly refer to exaggerated color changes to the body, installing large body kits, modifying exhaust systems, changing the engine model, etc. 2.

Does Maintenance Outside Affect Warranty?

Maintenance outside does not affect the warranty. However, there is a prerequisite: the repair shop must have Class II or higher qualifications, and you must keep the maintenance list and invoice for each repair or maintenance. In this way, even if problems arise, the 4S shop is still obligated to honor the warranty. Below is relevant information about the automobile three-guarantee law: "Regulations on the Repair, Replacement, and Return of Household Automobile Products": According to Chapter 3, Article 12 of the "Regulations on the Repair, Replacement, and Return of Household Automobile Products" (Order No. 150 of the General Administration of Quality Supervision, Inspection, and Quarantine), sellers of household automobile products must meet the following requirements: clearly indicate the repair network information, including the name, address, and contact number of the repairer agreed upon by the manufacturer. However, consumers have the right to independently choose a repairer from the above-mentioned repair network, and sellers must not impose restrictions. "Consumer Rights Protection Law": According to Article 9 of Chapter 2 of the "Consumer Rights Protection Law": consumers have the right to independently choose goods or services. This means that car owners have the right to compare, evaluate, and select, and to independently choose a repairer that suits them during maintenance and repairs. "Guidance on Promoting the Transformation and Upgrading of the Automobile Maintenance Industry and Improving Service Quality": Automobile manufacturers and their authorized sales and repair enterprises must not abuse automobile warranty clauses. As long as consumers use, maintain, and repair automobile products correctly according to the instruction manual, they cannot be denied the "three-guarantee" policy on the grounds that the owner has maintained the vehicle at an external repair shop.

What does the VSA vehicle stability control system light indicate?

vsa light illumination indicates that the vehicle's electronic stability control system is either deactivated or signifies a malfunction in the VSA system. The following reasons may cause the vsa light to illuminate: 1. Owner misoperation: Under normal circumstances, the vehicle's vsa system remains in the activated state (i.e., operational status). The sudden illumination of the vsa light occurs when the owner, unaware of the vsa system's function, manually switches its control button to OFF on the central console. In this state, the vsa system is manually deactivated. To turn off the vsa light, simply press the function button back to ON. 2. Vehicle hardware malfunction: If owner misoperation is ruled out, the illumination of the vsa light can be attributed to a fault in the electronic stability control system, including components such as the vsa system wheel speed sensor, steering wheel sensor, control unit, engine ECU, etc. When the vsa light illuminates due to vehicle hardware malfunction, it is imperative to have the vehicle inspected and repaired at an automotive repair facility.

Does the Pajero Sport have four-wheel drive?

The Pajero Sport does have four-wheel drive. Four-wheel drive refers to a vehicle maintaining all four wheels driving throughout the entire driving process, with the engine's output torque distributed to the front and rear wheels at a fixed ratio. This driving mode ensures excellent off-road and handling performance at all times, but it cannot adjust torque distribution based on road conditions and has relatively high fuel consumption. The Pajero Sport is a mid-size SUV under GAC Mitsubishi, with dimensions of 4695mm in length, 1815mm in width, and 1825mm in height, and a wheelbase of 2800mm.

What suspension does the Lamando use?

The Lamando uses a MacPherson independent suspension at the front and a multi-link independent suspension at the rear. Below is an analysis of the advantages of these two suspension types: 1. Advantages of the MacPherson independent suspension: (1) Excellent responsiveness and handling: The MacPherson suspension offers good responsiveness and handling, with a simple structure, compact size, low cost, and light weight, making it suitable for large engines and compact car bodies; (2) Longer effective distance: Reduces the force exerted on the body; (3) Large spring travel: Eliminates the need for three support points, making it easier to shape the front floorboard. 2. Advantages of the multi-link independent suspension: (1) Provides multi-directional control forces for more reliable tire performance: The multi-link suspension consists of three or more connecting rods, offering multi-directional control forces to ensure more reliable tire trajectories; (2) The main control arm adjusts the rear wheels: The main control arm can adjust the rear wheels to improve vehicle stability and effectively reduce tire friction.
