وصف
This left‑hand (driver side) electric brake assembly is designed for 10,000 lb and Quality trailer axles. The brake measures 12‑1/4" x 3‑1/2" and features a 5‑bolt mounting pattern (the axle flange has 6 holes, but only 5 are used). It comes as a complete backing plate with pre‑installed 1/2"‑20 threaded mounting studs (hardware not included). This brake is compatible with 10K and Quality axle systems requiring a left‑side replacement. Always verify your existing brake size, mounting bolt pattern, and axle rating before ordering. Sold individually – order a matching right side brake separately for a complete axle.
