Features to know about

Replace Both Brake Assemblies, Not Each Small Part

When the brake parts on both sides are worn, replacing each shoe, magnet, and spring separately can drag the job out. This kit gives you right- and left-hand assemblies for compatible 8,000 lb trailer axles, so the repair stays focused on swapping the assemblies and getting both sides back in service.

Self-Adjusting Brakes Cut Down on Manual Adjustment

Manual brake adjustments are one of those trailer jobs most owners would rather not repeat. These self-adjusting assemblies maintain proper brake adjustment as components wear, which keeps your braking performance more consistent and eliminates the need to crawl back under the trailer for manual brake adjustments.

Confirm the 8,000-lb Fit Before Teardown

Brake fit matters before the old assemblies come off. This kit includes the right hand, or passenger's side, and left hand, or driver's side, assemblies and matches 12-1/4" diameter x 3-3/8" wide brakes with a 4-bolt mounting flange pattern on 8,000 lbs axles. Mounting bolts and hardware are sold separately (BRKH12), so your install plan needs to account for those before the trailer's apart.

They didn't fit my axle. Customer support was extremely helpful with a return. I needed the brake for the post 2009.



by:

The brakes that I ordered arrived on time. And it was the correct product as advertised. If you’re needing ABS drilled brakes for a fifth wheel RV, I highly recommend Etrailer.



by:

Perfect fit for my Lippert 7k axles. The passenger side was worse than the driver's side. Wires were cut on both on passenger side. One of the passenger side completely fell apart when I removed the drum wit one lone spring still hanging on. While the driver's side only needed shoes, I decided to order new for that side also. That gave me self adjusting housings all around. Very pleased!!
