The Matco Aircraft Landing Systems WHLB4-DXTMH 4 INCH inch brake assembly is designed for use with Matco Aircraft Landing Systems wheels. This model uses an Internal caliper design and is designed to be used with the WHLD4 disc. The WHLB4-DXTMH is supplied with BPD.75MH brake plate adapter.
The M66-103 brake pad is used. This semi-metallic friction material compound was selected for its high friction performance and low fade at elevated temperatures to provide smooth stopping under high load conditions. The reline kit for this brake is the 2 BRL-2 which includes linings and rivets for two calipers.
Most models of Matco Aircraft Landing Systems brakes are upgradeable to higher torque configurations as engine size or tire changes. Check our brake conversion kits or call our technical support staff for your specific needs.
The WHLB4-DXTMH is designed for the following specifications:
|Energy Rating (FT-LBS)||93441 FT-LB|
|Torque Rating (@450 PSI)||3080 IN-LB|
This brake model uses the new PH-4XT caliper and replaces models using the older PH-2. The new assembly provides nearly 50% higher torque and is a direct replacement for the WHLB4 brake models. In addition to higher torque, the PH-4XT caliper is machined from bar stock instead of a casting as used on the PH-2!
This model uses two caliper in a single brake assembly. This is the highest torque model of the the B4XT series.
