6S Hydraulic Disc Brake Conversion Kit | 12-inch Rotor
All-in-one, DIY disc brake conversion kit for trailer axles. Go from an unbraked axle to 12-inch hydraulic with ease.
Trailer manufacturers, repairers, and owners alike often opt for mechanical disc brakes because of the simplicity. Unlike electric brakes, hydraulic discs don’t require any special equipment in your tow vehicle. Moreover, they provide safe braking, are easy to maintain, and spare parts are freely available.
Couplemate™ has put together this 6S disc conversion kit with 12-inch 2T rotors to suit single-axle trailers.

Brake Conversion Specifications
There are a 3 things to check before you go ahead.
#1 – Wheel Dimensions for 6S Discs
Your conversion kit will include plated disc rotors that were drilled and studded to the traditional 6 Stud Landcruiser stud pattern.
12-inch 6S Disc Brake Specifications
- Stud Pattern = 6 Stud Landcruiser
- Pitch Circle Diameter = 6 x 139.7mm PCD
- Stud-Centre to Stud-Centre = 69.85mm
- Stud Thread = M12 x 1.5
- Min. Wheel Centre Bore = 105mm
#2 – Bearing Profile for 2.25T Bearings
This conversion kit suits Australian 2.25T bearings. Trailer bearing profiles are denoted by the laser-engraved bearing numbers on the tapered roller cone (see example image).
Australian 2T (2.25T with NSK Bearings) profile will have the following bearing combination:
- Inner Bearing #: 30210J
- Outer Bearing #: 15123/245
This information is sometimes kept on file by the original trailer manufacturer. However, most customers resort to a “hands-on” approach.
#3 – Axle Profile for Hydraulic Disc Conversion
By default, the 6S Hydraulic Brake Kit includes a two-piece marine seal (#494013).
Moreover, 12-inch hydraulic disc brakes require a un-threaded anchor plate that is welded to your axle. Anchor plates come included in the kit, and as such, we’ll need to clarify your:
- Axle Shape: Round or Square
- Axle Size: 45mm, 50mm, etc.
That way, we can supply the right parts for easy installation!
