Purpose of the publication

This brochure is intended to be for guidance purposes

only and its contents are purely of a general informational

nature. The diagrams appearing in this brochure do not

adhere to all regulations of all countries, so please do not

forget:

– To follow the legal regulations in your country when

applying and maintaining brake systems.

– To follow your country’s regulations and safety

instructions for work behaviour and environment to

avoid accidents.

– That brake tests are mandatory before putting

vehicles on the road.

We have taken care to try and ensure the accuracy of the

information in this brochure. However, WABCO is not

responsible for any harm or damage caused by error or

inaccuracies that may be contained in this brochure.

This brochure is not intended to replace appropriate

advice and confirmation. Do always get WABCO

confirmation based on the trailer configuration you are

intending to build before proceeding.

1. Introduction

In the last few years, the trailer production has been

increased world wide. Trailer builders have to deal with

specific customer demands, and new regulations.

Some customers are interested in low-priced systems

for trailers in their region or in trailer systems which are

very popular outside Europe but that does not respond to

the European regulations (e.g. systems for road trains,

high-axle load systems).

Other trailer manufacturers (and also their customers)

are interested in trailer systems with high technical levels

like in Europe - e.g. for international transport or for

export.

WABCO aims to address these points with this new

brochure.

Introduction MEA 1.

General remarksMEA2.

2. General remarks

There are some general points to take into account

before choosing the right trailer system.

1. The drawings are modified to the newest

technical standard.

The pipe and hose sizes are redesigned to a clear

structure such as:

• Hose size in general: 11×4

• Pipe size for power between air tank and

consumer during braking process: 15×1.5 (at

least)

• Pipe size in general for other connections in the

brake system: 12×1.5

• Pipe size in the air suspension system in

general: 12×1.5

• Pipe size for lift bellow control: 8×1

• There were introduced some new technical

features such as coupling head with integrated

line filter for semi trailers

2. The part lists (especially fittings and pipe

lengths) are proposals.

WABCO makes a proposal for a system. Before

ordering, WABCO recommends:

• To create a prototype installation with the

selected system.

• To check that the proposed types of fittings are

suitable.

• To check the pipes and hoses quantities.

You may find more information concerning fittings in

the WABCO brochure 815 010 080 3 “Pipe coupling

list”. Please contact your WABCO representative for

any additional information or support.

3. Brake systems with ABS or EBS feature do

not contain any brake chambers.

It is assumed that brake systems with no ABS or

EBS feature are equipped with drum brakes.

Please, contact WABCO to request any other wheel

brake type.

It is assumed that in case of assembling trailer with

ABS or EBS feature, the brake chambers are

delivered by the axle manufacturers. Please,

contact WABCO for any additional brake chambers.

4. It is possible to adapt the planned brake

chambers in brake systems without ABS

feature.

The selection of the brake chambers depends on

the axle load of the trailer in full laden situation.

From our experience this can be defined as follows:

• Axle load 8…10t => brake chamber type 24"

• Axle load 12…16t => brake chamber type 30"

It is possible to modify the brake chamber that it is

independent of the axle load. It is necessary to

inform WABCO if the parts list is modified.

5. Trailer brake systems with automatic load-

sensing valve the load-sensing valve has to

be adjusted before installation.

The automatic load-sensing valves, LSV, in trailers

are “universal valves”.

”Universal” means that the valve can be used for

several trailers types.

“Universal” does not mean “plug-and-play”. It is

necessary to do an adjustment of the LSV before

installation into the brake system. All information,

the needed tools and adjustment procedure can be

find in the WABCO brochure 815 010 032 3 “LSV

testing equipment”.

The parameters for the adjustment must be

calculated.

There are several possibilities to get the parameters

for LSV adjustment such as:

• Calculation with “nomographs” - a big selection

of LSV nomographs can be found in the WABCO

homepage “http://www.wabco-auto.com/service

and support/inform”

• Calculation with “LSV calculation software” - you

may get this software as freeware from our

WABCO homepage “http://www.wabco-

auto.com/service and support/download” or

you'll get it from your WABCO partner

• Calculation with “trailer brake calculation” - this

service may be requested from WABCO. For

that WABCO needs a filled application form for

brake calculation - for further information see the

remarks for brake calculation in this chapter.

6. To use trailer EBS, it is necessary to have a

brake calculation for the trailer.

The trailer electronic brake system, TEBS, is a

“universal system”. It can be used for most of the

popular trailers types.

After the installation of a TEBS it is vital to adjust the

TEBS to the specific conditions of the trailer.

This adjustment can only be done with a PC and the

accessory software. WABCO offers in his range the

adapter cabling to connect the PC with the trailer

system.

For more information please contact your WABCO

representative.

This job can only be done by trained people. For that

it is necessary to contact your WABCO

representative for training and support.

If there is no adjustment of the TEBS after

installation the TEBS will not work properly and the

vehicle user will have several problems.

The parameters of how to adjust the trailer will be

calculated with a brake calculation. WABCO offers

the service to do a brake calculation for the trailer

manufacturer. For further information see the

remarks for brake calculation in this chapter.

7. Brake systems in trailers with ABS feature

and TEBS are to activate with a start-up

procedure.

WABCO insists on doing a start-up procedure in

trailer brake systems with electronic components

(ABS, TEBS).

The start-up procedure involves a PC and the

accessory software. WABCO offers also the

adapter cabling to connect the PC with the trailer

system.

The start-up procedure has the following benefits:

• TEBS will only work after successful start-up

procedure

• The start-up procedure gives the certainty that

the parts are assembled in the right position and

the system works well

8. WABCO recommends having a brake

calculation for each type of trailer brake

system.

The brake systems in this brochure do not consider

the specific conditions on the trailer like trailer

dimensions, axle type, wheel brake type, tyre type,

etc.

On the basis of the brake calculation it is it is maybe

possible to determine whether the brake system is

conformant.

For a proper brake calculation it is important to fill

the application form “technical vehicle data”.

The application form is attached at the end of this

chapter. There is also an example how to fill this

form. For support, please do not hesitate to contact

your WABCO representative.

9. There is a levelling valve in trailer air

suspension system which has to be

adjusted.

The levelling valve in air suspension system has a

lever. The lever length is to adjust for optimal

suspension conditions.

The levelling valve 464 006 100 0 has the additional

feature “height restriction”. The height restriction is

adjustable. Remove the rubber caps on the valve

ottom and use the screw to adjust.

For support, please do not hesitate to contact your

WABCO representative.

10. In trailer air suspension systems with lift

axle control valve 463 084 000 0 could be

necessary to adjust the lift axle control

valve before installation.

The lift axle control valve, LACV, in trailers is a

“universal valve”. It can be used for several requests

for lift axle control. The LACV is to lower the lift axle

manually.

The lift of the lift axle will be done automatically. In

the delivery condition the LACV is adjusted to lift the

axle on a bellow pressure of approx. 4 bar (switch

point). If there is a need to lift the lift axle in another

switch point it is adjustable.

The procedure of this adjustment can be found in

the brochure 815 010 034 3 “Air braking equipment

for towed vehicles in accordance with council

directive 71/320/EEC”.
