Description

Technical Parameters

Core Product Function

WG9100443001 is an exclusive front brake pad for HOWO series heavy-duty trucks, serving as a key friction component of the vehicle brake system. It cooperates with the brake disc to generate braking friction force, converting the kinetic energy of the vehicle into thermal energy and realizing stable deceleration or parking of the vehicle. The product features high friction coefficient stability, excellent heat dissipation performance and strong wear resistance, effectively shortening the braking distance of heavy-duty trucks under full-load conditions, improving driving safety, and adapting to harsh working conditions such as long downhill, high-temperature operation and frequent braking of heavy-duty trucks.

Maintenance and Precautions

Installation: Clean the brake disc surface to remove rust and debris before installation; apply a thin layer of high-temperature lubricant on the back plate and the contact surface of the brake caliper to reduce noise; ensure the brake pad is firmly installed in the caliper, no looseness; step on the brake pedal several times after installation to make the brake pad and brake disc fit closely.

Inspection: Check the friction layer thickness every 20,000 kilometers; check whether there is delamination, cracking or rust on the back plate; check the brake disc for wear and runout, and replace the brake disc in time if the wear is excessive.

Storage: Store in a dry and ventilated warehouse, avoid contact with water, oil and corrosive substances; place in a flat place, no stacking pressure; the storage period should not exceed 2 years, and the expired products should be re-inspected before use.

Replacement: Replace the brake pads of the same axle in pairs to ensure consistent braking performance; do not mix brake pads of different brands or models; after replacement, perform a road test to confirm the braking effect is normal.

Frequently Asked Questions (FAQ)

Q1: How to confirm that this brake pad matches my HOWO truck?

A1: You can provide the vehicle VIN code, model or brake caliper model, and we will verify the compatibility of the brake pad's dimensions and installation structure with your vehicle to ensure perfect fit.

Q2: What is the advantage of the semi-metallic formula of this brake pad?

A2: The semi-metallic formula has excellent heat dissipation performance, which can quickly dissipate the heat generated by braking, avoid thermal decay, and has high wear resistance, which is especially suitable for the heavy-load and frequent braking working conditions of heavy-duty trucks.

Q3: Can samples be provided for performance testing?

A3: Yes, sample supply is supported. The sample fee can be fully deducted from the subsequent formal order, and the sample delivery cycle is 2-3 working days.

Q4: What are the signs that the brake pad needs to be replaced?

A4: When the friction layer thickness is less than 3mm, or when there is abnormal noise during braking, longer braking distance, or friction layer delamination, the brake pad should be replaced in time.
