Product Description
EBS MODULATOR
WABCO Trailer ABS / EBS Modulator System Assembly
Made as a single modulator, the WABCO Trailer ABS / EBS Modulator System Assembly merges electronic control and pneumatic valve functions in one unit for trailer braking systems. Wheel speed and load data pass through the module continuously, and the system fine-tunes braking force at each axle instead of applying flat pressure across the trailer. This keeps tires rolling evenly under hard braking, so flat-spotting from repeated stops drops off. Fully loaded articulated combinations get response rated to 145.0 psi (10.0 bar) at the module, and the WABCO 4801020140 assembly keeps brake response fast across the trailer's length.
EBS Trailer Modulator
Features & Benefits
- Balances brake force across tandem axles as trailers carry uneven cargo loads
