Hydraulic Disc Brake Pad

Hydraulic disc brake pad fits all brands of Australian trailer brakes including Al-ko, Trojan and Meher.

Pads are sold separately. Also available are stainless disc pads from Trojan.

Hydraulic pads installation process

• Remove caliper from the mounting bracket
• Remove the disc pads from the caliper.
• With the pads removed, check the piston for wear and tear.
• As a precaution have a seal kit on hand.
• If you have a compressor, blow air down the hydraulic fluid input hole. This will push the piston out.
• Inspect the piston and replace it if necessary. If the piston is stuck inside the caliper, a hammer and pointed drift will be needed to remove the piston.
• You will need to destroy the piston to remove it if it has swollen.
• Replace the piston with a stainless piston. Purchase from the link below
• Use silicone grease when re-installing. Normal grease does not mix with hydraulic fluid.
• With the piston installed, re-insert the disc pads.

Alternatively, your local trailer specialists will do all this work above for around $1000 for a tandem axle trailer.
