If you replace the current brakes on your trailer with the same uni-servo drum brakes and no lockout actuator (like #T2351000), the brakes will deliver 20 percent braking when traveling in reverse. However, the more pressure you apply going…

For your 12" x 2" brake drum you can use either our part #AKBRKR-M12 or the Redline #BP01-180 to replace the brake magnet on your Hayes/Al-KO brake assembly. Both magnets have 2 wires coming from them and it doesn't matter…

The Never Fail Bushings like part #TRBU11566 and the Bronze Bushings like part #D014-077-00 are designed for 1-3/4" wide double eye leaf springs. There is not a version of these which are an upgrade over the factory nylon bushings for…
