3/4-inch Hydraulic Trailer Master Cylinder

This 3/4-inch Hydraulic trailer master cylinder suits 1450kg override couplings that tow single axle trailers. 3/4-inch refers to the piston bore size.

In terms of compatible wheel sizes, this master cylinder is best suited for 14, 15 and 16-inch wheels.

A hydraulic cylinder park brake is required (and not included) for hydraulic braking systems. You can purchase one here.

Installation Instructions

Fit the master cylinder bracket on the rear bolt mounts
Bolt hole mounts are 54mm between centres
Select 1/2-inch bolts that bolt right through your bracket, coupling and drawbar
Disconnect the parking brake
Adjust the lower nut 2mm from the back of the override, then lock it off.

Please Note: Bled and adjusted brakes are the key to an efficient hydraulic braking system. Once the brakes are bled, tighten the nut on the back of the brake lever.

Fitting Advice from Our Engineer

You must have at least 2mm free play, between 2mm and 5mm, when the hydraulic brake pads start to wear
If there is no free play, as soon as the brakes start to work and get a little warm, you will begin to get brake build-up, increasing heat and burning out your brakes or even popping the seals in the master cylinder

What type of brake fluid should I use?

DOT 3 or DOT 4 should be used in your boat trailer. This type of hydraulic oil does not absorb water, but the silicone in DOT 5 can cause seals to swell and bind up caliper pistons.

Why this Master Cylinder is an Essential Component

The 3/4-inch trailer master cylinder is the crucial braking component used on single-axle braked trailers with two-wheel cylinders.

You’ll also buy various braking system components, such as 9-inch hydraulic brake shoes, hydraulic drum brakes, and electric brake parts.
