Brake Description

MAN-028 SIBS SERVICE MANUAL - DRIVELINE BRAKING SYSTEM (REV 2) 7

2. Brake Description

The Sealed Integrated Braking System (SIBS®) is a Spring Applied Hydraulic Release system operating in isolation from

any other braking system fitted to the vehicle. SIBS® has been configured for mounting to the driveline of heavy

goods vehicles. The brake is bolted to the input side of the rear differential carrier. The torque generated by the

brake is transmitted to the rear wheels via the differential and axle shafts. There are three variants of the brake:

HGV15, HGV16 and HGV17, designed for fitment to the following vehicles with and without diff locks:

• Heavy Goods Vehicle 15 (HGV15):

o 24,500 kg GVM 6x4 trucks with Meritor RT40-145 tandem drive rear axles

o 24,500 kg GVM 6x4 trucks with Meritor RT46-160 tandem drive rear axles

o 26,000 kg GVM Hino FM Series 6x4 trucks

• Heavy Goods Vehicle 16 (HGV16):

o 10,000 kg GVM Isuzu FSS 550 4x4 trucks

o 13,500 kg GVM Isuzu FTS 800 4x4 trucks

o 13,000 kg GVM Hino Ranger Pro 8Z 4x4 trucks

• Heavy Goods Vehicle 17 (HGV17):

o 18,000 kg GVM MAN TGM Series 4x4 trucks

o 18,000 kg GVM MAN LE Series 4x4 trucks

The SIBS® brake operates as a spring applied hydraulic release emergency driveline brake only. The hydraulic system

has been designed to modulate the application preventing shock loads damaging the driveline.

SIBS® is an enclosed single rotor high-speed disc brake. It provides greater reliability in a compact enclosed package.

The brake is designed for harsh mining environments and is able to be submerged for short periods without affecting

operation.

Important:

2.1.1 The brake is intended as an emergency brake only for use in the event of a service brake system failure.

The system is not designed as an additional service brake.

2.1.2 Do not perform more than one emergency stop from 40 kmph or more every 20 minutes as the brake

may overheat.

2.1.3 The SIBS® Emergency Driveline brake is not designed as a vehicle retarder and should only be used in

the case of an emergency.

2.1.4 The SIBS® Emergency Driveline Brake System is primarily designed for “off highway” use. Whilst it is

possible to operate the brake at highway speeds without damage, unintended application of the brake

will rapidly and effectively arrest the vehicle. ABT recommends that the brake is disabled for highway

use by installing the supplied retractor bolts. This recommendation applies to delivery of the vehicle to

site and any other extended “on highway” use.

WARNING:

The retractor bolts must be removed to re-commission the brake prior to the vehicle commencing service.

Brake Schematics

MAN-028 SIBS SERVICE MANUAL - DRIVELINE BRAKING SYSTEM (REV 2) 11

5. Brake Schematics

Key features:

The brake is bolted to the bearing cage on the input side of the rear differential.

The bearing cage located on the input side of the rear differential is machined to provide a seal surface and

spigot for location of the brake.

The rotor is allowed to ‘float’ on a spline machined into a purpose built yoke.

The spline transmits the torque from the rotor to the input pinion at the differential.

The yoke is designed to incorporate an additional seal surface to contain the SIBS® cooling fluid inside the

brake.

Pad wear indicators are included on the HGV15 and HGV16 brake variants and must be inspected according

to the service schedule.

Adjustable pistons to compensate for pad wear are included in the HGV17 brake variant.

5.8 HGV17 Adjustable EMMA™ Piston

The HGV17 brake is installed with an adjustable piston that allows compensation for pad wear. Piston adjustment

must be carried out manually during service.

Braking torque is directly related to spring deflection. As the pads wear, the spring deflection increases thereby

reducing the spring force and braking torque. In order to compensate for this, the EMMA™ piston has an adjustable

plunger as shown below.

Arrangement of the piston and springs is shown in Figure 3. The springs act to apply load to the pads, and the

hydraulic pressure on the piston acts against the springs.

The length of the piston can be adjusted by accessing the centre of the piston thru the spring cover plug, removing

the grub screw and rotating the plunger clockwise (to lengthen the piston) or anti-clockwise to shorten; Figure 4.

Hydraulic System

MAN-028 SIBS SERVICE MANUAL - DRIVELINE BRAKING SYSTEM (REV 2) 21

6. Hydraulic System

The hydraulic system consists of:

Hydraulic pump

Solenoid valve – normally open

Flow control valve

Pressure switch

Filter

Hydraulic manifold

Heavy duty hydraulic hose, pipes and fittings

6.1 To Release the Brake

6.1.1 The normally open solenoid valve is powered shut, blocking the return path to tank.

6.1.2 The pump runs generating pressure to release the spring applied brake.

6.1.3 The pressure switch – set to 1500 psi for HGV16 and HGV17; 2100 psi for HGV15 – turns the pump off

when the pressure in the line exceeds this value.

6.1.4 Any loss of hydraulic pressure below 1500 psi for HGV16 and HGV17 or 2100 psi for HGV15 will cause the

pump to run and generate more pressure.

6.2 To Apply the Brake

6.2.1 Solenoid valve opens allowing pressure to dump via a flow control valve to zero.

10.6 Adjusting for Pad Wear (HGV17 only)

The HGV17 does not come with a pad wear indicator as standard however the piston length can be adjusted to

account for pad wear thereby maintaining the brake torque. Follow the adjustment procedure below:

10.6.1 Tag the vehicle as per site safety requirements, apply the vehicles park brake and install wheel chocks.

10.6.2 Lift the rear axle from the ground to allow the wheels to rotate, as this will be necessary to check for free

rotation of the brake after adjustment.

10.6.3 Release the driveline brake using the dash mounted control box

10.6.4 Access the 4 x spring cover plugs (10-3190) on the brake housing and remove.

10.6.5 Remove the 4 x grub screws from each piston

10.6.6 Using a flat screw driver, turn the 4 x plungers in each piston clockwise until they stop.

10.6.7 Back off each plunger by ¼ of a turn.

10.6.8 Engage the brake using the control box. This applies load to the pistons and ensures the plungers do not

rotate when re-installing the grub screws.

10.6.9 Reinstall the grub screws and firmly tighten using the Allen key.

10.6.10 Before installing the 4 x spring cover plugs, release the brake and check for free rotation of the brake.

10.6.11 Re-install the 4 x spring cover plugs.

10.6.12 Use Silicone to fill in the heads of the spring cover plugs to reduce corrosion and assist with future

servicing.

Figure 15: HGV16 brake mounted to rear differential. Figure 16: Cross section schematic of HGV17 adjustable piston.

10.6.13 Adjustment of the EMMA™ piston will also be required when installing new pads or stripping the brake.
