Power brake towing equipment for caravans, boat trailers and horse boxes for use on any type of axle configuration.

With the TV2381SA you get AUTOMATIC and SIMULTANEOUS braking action on both car and trailer when applying the foot brake.

Towing can be a hazardous business... Up hills, down hills, around hills or just straight going in heavy traffic. Driving with too many emergency situations could turn a peaceful holiday towing into a nightmare trip for the driver and passengers.

Sudden braking may cause your caravan, boat trailer or horse box to jack-knife which, if not controlled, can be very dangerous. All these things can be overcome by installing the Wingate - PBR TV2381SA kit (see Fig. 2) to control the trailer brakes, whether mechanical or hydraulically operated. This is a single line, air suspended, and hydraulic type installation kit.

This kit when installed, and in conjunction with either trailer kit TV2340 or TV2341 with a VH116 hydraulic booster, will allow more effective braking control at the driver's fingertips through the use of the PV109 hydraulic vacuum control valve. He will be able to correct the balance of braking required between car and trailer.

All are vacuum assisted brake systems for use with mechanical and hydraulic trailer brakes.

These systems can be installed on either single axles or double axles, and also in an "automatic stop" breakaway configuration for use on light or heavy load and live stock carrying trailers.

IMPORTANT FEATURES:

The TV2381SA car section will, when:

Applying the brake pedal automatically operate the trailer brakes with the use of the vacuum-hydraulic PV109 control valve, which is interconnected with the existing hydraulic brake system of the car, together with a vacuum hose which is interconnected with the existing booster vacuum hose or engine, and exits at the rear of the towing vehicle to a sealed vacuum female connector, (see Fig. 2).

The balance (or ratio) between the car and trailer brakes can be varied to suit all road and load conditions by the turning of the control handle, which is connected to the PV109 valve (see Fig. 3). Turn the control handle clockwise to increase the effect of the trailer brakes, or anti-clockwise to decrease it. (See Fig. 4.)

The hand-operated control handle/lever is fitted in the drivers' compartment and, when used independently, applies the trailer brakes only, overriding all foot control settings. This is a very important safety feature in case of trailer sway, as by pulling on the hand lever only (no foot brake action required) this action will apply only the trailer brakes. This will help, in case you ever get into a swaying motion, to prevent a jack-knife / tail-wagging situation from occurring, (see Fig. 1.)

The PV109 hydraulic reaction valve is mounted in the engine compartment in a convenient position to allow the control cable to be fed through the firewall in the engine compartment, connecting it to the control handle assembly situated in the driving compartment, and to the car hydraulic system, (see Fig. 2.)

The T659 vacuum reserve tank, which is fitted with a safety vacuum non return valve, is also fitted n the engine compartment, and is interfaced with the vacuum pipe connected to the brake booster and/or engine inlet manifold. This will guarantee that there is always a vacuum available to activate the brake chamber fitted to the trailer, even if the engine stalls or cuts out, (see Fig. 2.)

TYPES OF TRAILER BRAKING INSTALLATIONS:

1. MECHANICAL type with the TV2340 installation (see Fig. 5) using the B330R vacuum chamber.

2. HYDRAULIC type installation using the VH116. (see Fig. 6). This specially developed unit puts out hydraulic pressure using vacuum applied from the TV2381SA when installed.

3. BREAKAWAY WITH AUTOMATIC STOP using the PV48A interfaced with either the MECHANICAL or HYDRAUALIC installations in conjunction with a large Vacuum Reservoir Tank. This system is mandatory in certain installations, e.g. horse boxes or live stock trailers and in certain weight loads.

Trailer configurations of Single or Dual axles whether mechanical or hydraulic braking systems use either of these assemblies. The TV2340 type is used on mechanical axle applications and the TV2341 - VH116 on hydraulic axle applications. (see details in Fig. 7).

Electric vacuum pump kit #5202000 provides a primary or secondary source of vacuum and is ideal for all diesel driven vehicles.
