Instructions for Brake Caliper Kit
6K, 7K or 8K Hydraulic Disc Brakes
Notice to Buyer
It is recommended that all brakes be replaced at the same time to ensure
balanced braking performance.
Remove the old brake calipers
1. Jack up trailer and secure on adequate capacity jack stands. Follow
trailer manufacturers recommendations for lifting and supporting the
unit.
CAUTION
Do not lift or support the trailer on any part of the axle or suspension
system. Never go under any trailer unless it is properly supported on
jack stands which have been rated for the load. Improperly supported
vehicles can fall unexpectedly and cause serious injury or death.
2. Remove the wheel from the hub, leaving the brake exposed.
3. Disable the brake actuation system. Check that the hydraulic system has
zero pressure and that the hub and rotor rotates freely.
4. For brakes produced after April 2008, the crossover brake line also
attaches to the inboard side of the caliper mounting bracket using the
metal tube clamp. Slide the clamp over the crossover brake line and
bend it to the closed position. Apply anti-seize or similar thread lubricant
to the 1/4-20, 1/2" bolt. Attach the tube clamp to the threaded hole in
the caliper mounting bracket using the 1/4-20, 1/2" length bolt. Torque
to 85-100 In. Lbs.
5. Remove the hose from the caliper, then remove the four caliper mounting
bolts. Do not allow the caliper to hang from the hose.
Installing the new brake caliper
1. First inspect the brake assembly for grooves, aking, cracks, heat
checking, thickness variation, insufcient rotor thickness, and look to
see that the mounting hardware is straight. Replace any component as
needed (or desired) per manufacturer recommendations.
