Hydraulic Caliper Anchor Plate
Hydraulic Caliper Anchor Plate
Hydraulic Caliper Anchor Plate suit hydraulic calipers on all Al-ko 10-inch and 12-inch disc rotors.
Anchor plates are 10mm thick and 90mm between holes for Australian brake calipers.
7/16 inch UNF is the hole size.

Couplemate suggests all anchor plates are dry fitted and tacked welded before the welding process is finished. In most cases, failure to dry-fit every anchor plate will result in wrong fits.
How to dry-fit anchor plates?
- Insert bearings into the rotor with no grease and fit the rotor to the axle. (tighten)
- Assemble the caliper onto the Hydraulic Caliper Anchor Plate and tighten it.
- Align the caliper over the rotor and tighten the pad adjustment bolt. (note: place a zip tie or Q strap between the rotor and caliper to stop the caliper from touching the rotor when it is spinning.)
- Align the caliper on the slides by sliding the caliper backwards so that a gap of approximately 1mm or more exists on either side of the arms holding the pads into position. The caliper will slide back when the pads wear.
- Carefully tack the mounting plateDisassemblele the entire setup except for the mount plates.
- Tape the bearing journals.
- Carefully weld the small flat section of the mounting plate on the sides, then weld the central part farthest away from the bearing journal. (note: Weld one side of the mounting plate is sufficient)
- Repeat on the other end.
- When testing,g ensure the discs brake quickly and evenly. Air bubbles in the hydraulic line will significantly diminish the effects of braking.
Grease bearings with high-temperature grease and assemble rotors. Tighten the adjustment bolt until tig,ht, then back off 1/2 turn and lock the thread with the lock nut.
Note: Grind galvanising on your axle back to bare metal before welding. After welding, apply a spray pack of cold gal while the mount plates are still hot.

Importantly, anchor plates should be installed at an angle that clears the trailer or caravan springs.
