$605.00 – $645.00 inc GST
45mm Round Hydraulic Drum brake kit to suit 9" drums. Suits 2000kg override couplings with a master cylinder — single Axle rating 1450kg.
Hydraulic Axles are suitable for trailers and caravans.
The rating of this axle is 1450kg as this axle uses Ford Slimline bearings.
9" hydraulic braked axles are very simple to install. Attached the Hydraulic backing plates to a weld ring, welded to the rear of the axle shoulder.
The hardest part of the entire job is to align the weld rings perfectly.
We recommend customers dry-fit the brake backing plates and mount brackets, without grease. Once the drum is in position and locked with the axle nut, tighten the brake shoes.
Align the backing perfectly with the hub drum and then spot weld the ring in 4 places. Re-adjust where necessary and then finished the welding on the ring.

Calculating The Correct Axle Measurements
As a result of viewing the video above, calculate the face to face measurement.
- Measure the offset wheel. The wheel offset is the distance between the inside of the hub and the outside of the rubber.
- Add 50 mm to the offset. Alternatively, choose your own distance between the rubber and the chassis.
- Multiply by 2 for both sides. Add your chassis width to the above number.
Metric to Imperial Converter
Convert Imperial (inches) to metric (mm)
Still unsure of what measurements to take? Check out this handy guide below:
[P] - Check material specifications. What size and profile is the axle (for example, 45mm Square)
[T] - Overall axle length (tip to tip)
[F] - Hub face to hub face measurement
[A] - Chassis width
[C] - Tyre clearance
[B] - Back offset
[H] - Tyre to chassis
[G] - Axle pad centres
Identifying Bearing Combinations
You will also need to identify your bearing combination which can be done by pulling off a hub and bearings, and locating the number laser engraved onto the bearing. You will require both the inner and the outer bearing number.
