Overview
The ZF 2095.317.022 BRAKE PLATE is a critical friction component engineered for heavy-duty construction machinery transmissions. This OEM genuine part sits within the multi-disc brake pack assembly, where it engages against steel reaction plates to generate the clamping force required for controlled deceleration and parking brake functions. Designed to withstand extreme thermal loads and high-pressure hydraulic actuation, the SKU 2095.317.022 ensures consistent torque transmission during aggressive shifting cycles. Its placement directly adjacent to the 2095109020: DIFFERENTIAL and the 2095209037: DIFFERENTIAL assembly means this brake plate must maintain precise flatness to prevent uneven wear across the drivetrain.
Symptoms of Failure
- Gradual gear slipping under load: When the friction material on the 2095.317.022 wears below 0.5mm, the brake pack loses clamping force, causing the transmission to slip during uphill grading or heavy bucket loads.
- Delayed engagement when shifting from neutral to drive: A worn brake plate increases clearance within the pack, resulting in a 2-3 second lag before the machine responds to throttle input.
- Metallic grinding noise during turns: Warped plates create intermittent contact with the 0750117075: TAPER ROLLER BEARING, producing a distinct chatter that worsens as operating temperature rises.
- Dark, burnt transmission fluid with particulate matter: Overheated friction material sheds carbon deposits into the oil, which can clog the 2095309059: DIFF.HOUSING lubrication passages.

Compatibility
This brake plate is primarily designed for ZF WG180 and WG200 series powershift transmissions commonly found in wheel loaders, backhoes, and telehandlers. It also fits select ZF 4WG-200 and 6WG-200 variants used in compact excavators. The 2095.317.022 is interchangeable with earlier revision 2095.317.020 and 2095.317.021 plates, though we recommend replacing the entire brake pack as a set. For differential-side applications, pair this plate with the 4482360002: AXLE BEVEL GEAR and 2095309081: DIFFERENTIAL AXLE to ensure proper load distribution.
