Brake Fluid DOT 4
Shengxiang DOT 4 Brake Fluid is presented in a 500G Intense package for hydraulic brake-system service. The product label highlights high-performance synthetic brake fluid, excellent thermal stability and superior protection. Use only where the vehicle or equipment manufacturer specifies a compatible brake-fluid grade.
Six performance areas engineers consider in a brake fluid
Brake fluid transmits pedal force through a sealed hydraulic circuit. Selection is not only about the DOT label: boiling behavior, low-temperature flow, moisture control, corrosion protection, compatibility and cleanliness all matter. Exact Shengxiang values should be taken from the approved TDS/SDS.
Hydraulic Force Transfer
Brake fluid carries pressure from the master cylinder to calipers or wheel cylinders. Correct fluid condition supports consistent hydraulic response.
Pedal-to-caliper responseThermal Stability
Repeated braking can heat calipers and nearby fluid. Brake fluid must remain suitable for hydraulic operation across the intended temperature range.
Label claim: excellent thermal stabilityBoiling Performance
Dry and wet boiling-point behavior is central to brake-fluid classification because vapor formation can reduce hydraulic effectiveness.
Verify official DOT 4 test valuesMoisture Management
Conventional DOT 3 / DOT 4 family fluids are hygroscopic, so moisture absorbed over time can influence boiling performance and service condition.
Keep container tightly sealedCorrosion & Component Protection
Brake systems contain metals, elastomers and precision bores. Approved brake fluid should provide suitable corrosion control and material compatibility.
Label claim: superior protectionClean, Controlled Fluid Condition
Contamination, incorrect mixing or unapproved fluids can affect seals, valves and braking performance. Always use clean tools and follow the vehicle maker's procedure.
Service discipline mattersMove the slider to increase hydraulic brake pressure
This is a visual engineering illustration, not a product test. As simulated pedal pressure rises, the caliper pads move inward, rotor speed decreases and the hydraulic line pulses faster.
From pedal input to controlled deceleration
The sequence below describes the general brake-system principle and is not a claim of measured Shengxiang product performance.
Brake Pedal Applied
Pedal force acts through the booster and master-cylinder mechanism according to vehicle design.
Pressure Builds
Brake fluid transfers hydraulic pressure through lines and control units toward each brake actuator.
Caliper Clamps Rotor
Pistons move pads toward the rotor, creating friction at the wheel-end braking assembly.
Motion Becomes Heat
Friction removes kinetic energy from the rotating system, slowing the wheel and generating heat.
What buyers should understand before choosing DOT 4
These are general brake-fluid engineering considerations. They do not substitute for the vehicle maker's specification or Shengxiang's approved TDS/SDS.
Start with the exact brake-fluid specification printed in the owner's manual, service information or reservoir-cap instructions.
Never select only by package appearance.Heavy braking, towing, mountain driving and performance use can raise brake-system temperature and increase the importance of boiling performance.
Confirm dry / wet values in the official TDS.Brake fluid condition changes with time and moisture exposure. Keep new fluid sealed and avoid leaving service containers open.
Follow the vehicle maker's service interval.Do not assume every brake-fluid chemistry or DOT category can be mixed. Confirm the required fluid family and compatibility before service.
Avoid unverified mixing.Parameters to verify in the TDS / SDS
No numerical performance values are invented on this page. Replace “Confirm TDS” only when approved Shengxiang DOT 4 technical documentation is available.
| Technical Parameter | Why It Matters | Shengxiang Value |
|---|---|---|
| Dry Boiling Point | Indicates boiling resistance of fresh fluid before significant moisture uptake. | Confirm TDS |
| Wet Boiling Point | Represents boiling behavior after controlled moisture conditioning and is important for aged-fluid performance. | Confirm TDS |
| Low-Temperature Viscosity | Affects fluid response through valves and narrow passages during cold operation. | Confirm Test / TDS |
| pH / Chemical Stability | Relevant to fluid condition and protection of metallic brake-system components. | Confirm TDS |
| Corrosion Test Performance | Helps demonstrate suitability for the metals commonly present in hydraulic brake systems. | Confirm Test / TDS |
| Rubber / Seal Compatibility | Brake fluid must be suitable for the seals and elastomer components used by the vehicle manufacturer. | Confirm Documentation |
| Water Content / Moisture Control | Moisture condition can influence boiling performance and long-term service condition. | Confirm TDS / QC |
| DOT 4 Standard / Approval Basis | The official document should identify the standards, test methods or approvals that support the DOT 4 designation. | Confirm Official Documentation |
Why fluid condition affects more than the brake pedal
Heat, Moisture & Vapor Control
Brake fluid operates near heat-generating components. If fluid condition deteriorates, boiling resistance can be reduced and vapor formation can compromise hydraulic response.
ABS / ESC Hydraulic Control Considerations
Modern braking systems can route fluid through compact pumps, valves and control blocks. Correct fluid specification, cleanliness and suitable low-temperature flow are therefore important.

Hydraulic brake-system service where DOT 4 is specified
These are general application categories only. Use Shengxiang DOT 4 only when the actual product specification matches the vehicle or equipment manufacturer's requirement.
Passenger Vehicles
Hydraulic braking systems where the OEM specifies DOT 4 or a compatible approved fluid.
SUVs & Light Vehicles
Brake-system maintenance subject to the manufacturer's fluid specification and service procedure.
Motorcycles
Hydraulic brake or clutch circuits only where DOT 4 is specifically required by the manufacturer.
Workshop Service
Fluid replacement, bleeding and hydraulic brake servicing performed with clean, approved equipment.
Four practices that help protect brake-system integrity
Choose and service in four checks
Check Vehicle Requirement
Confirm the exact brake-fluid grade required by the vehicle or equipment manufacturer.
Verify Product Documentation
Check the approved Shengxiang TDS/SDS for standards, boiling behavior, viscosity and compatibility information.
Use Clean Service Practice
Prevent contamination, follow the specified bleeding sequence and use suitable service equipment.
Follow the Service Interval
Replace brake fluid according to the vehicle maker's time, mileage and condition requirements.
Technical publishing note: do not publish numerical dry/wet boiling points, viscosity values, pH, corrosion-test results, standards, OEM approvals, compatibility claims or service intervals for Shengxiang DOT 4 until those values are taken from approved product documentation.
Frequently asked brake-fluid questions
Can DOT 4 be used in every vehicle?
No. Use the exact brake-fluid specification required by the vehicle or equipment manufacturer. Do not substitute fluid types based only on the DOT number.
Why does brake fluid need periodic replacement?
For conventional hygroscopic brake-fluid families, moisture exposure and normal service can change fluid condition over time. Follow the vehicle maker's specified replacement interval.
Can I mix DOT 4 with another brake fluid?
Do not assume compatibility. Different brake-fluid chemistries and specifications may not be interchangeable. Confirm the vehicle requirement and approved technical documentation before mixing.
What should a buyer provide when requesting a quotation?
Provide the market / destination, required DOT grade, bottle size, quantity, vehicle or application context, branding requirement and any required standard or approval documentation.
Is the braking animation a product performance test?
No. The animation is only a visual explanation of hydraulic braking principles. Product performance must be supported by approved laboratory data, TDS/SDS and applicable documentation.
