Disc & Drum Land Rover Freelander L314

INTRODUCTION

This vehicle is equipped with Anti-Lock Brake System (ABS) as standard equipment. ABS features 4-wheel electronic traction control and hill descent functions as well as anti-lock braking and electronic brake distribution. This article contains information on repair and service of non-ABS portion of the brake system. For servicing and diagnosing ABS portion of braking system, see appropriate ANTI-LOCK article.

BRAKE SYSTEM

Vehicle braking is provided by disc brakes on the front wheels and drum brakes on the rear wheels. The foot brakes are operated by a TEVES Mk25, 4 channel system controlling diagonally split, dual circuit hydraulic system with a vacuum enhanced brake vacuum booster power assistance. (Scheme 1) A cable operated parking brake operates rear brakes. (Scheme 2)

Scheme 1

Scheme 2

FRONT BRAKES

The front brakes each comprise a hub mounted, single piston caliper assembly and a vented disc. The inboard side of the disc is protected by a mudshield. When hydraulic pressure is supplied to the caliper, the piston extends and forces the inner pad against the disc. The caliper body reacts and slides on the guide pins to bring the outer pad into contact with the disc. (Scheme 3)

Scheme 3

REAR BRAKES

The rear brakes each comprise a hub mounted backplate and drum containing leading and trailing brake shoes when operated by the foot brake. An adjuster rod is incorporated to automatically adjust the brake shoes to compensate for wear of the brake linings. Adjustment occurs during operation of the foot brake. When hydraulic pressure is supplied to the wheel cylinder, the cylinder extends and forces the brake shoes against the drum. When a force is supplied to the shoes via the hand brake lever and cables, both brake shoes become leading. (Scheme 4)

Scheme 4

HYDRAULIC SYSTEM

The hydraulic unit of the modulator consists of a pump, 12 solenoid operated valves, and an accumulator and damper chambers. Each brake unit has its own inlet and outlet valves. The hydraulic system operates the brakes in response to brake pedal movement. For normal brake operation, brake pedal movement is assisted by the brake vacuum booster assembly and transmitted to the master cylinder assembly. The master cylinder assembly converts brake pedal movement to hydraulic pressure. Primary and secondary brake pipe circuits supply the hydraulic pressure to the brakes

1. Primary circuit supplies left front and right rear brakes.
2. Secondary circuit supplies right front and left rear brakes.

See

(Scheme 5)

. A Red, brake warning lamp in the instrument pack illuminates if the fluid level in the hydraulic system falls to an unsafe level. The brake fluid level is checked via a brake fluid level switch in the brake fluid reservoir. On right hand drive vehicles the brake fluid reservoir is remotely located on a bracket on the bulkhead. Left hand drive vehicles have the brake fluid reservoir in the usual position on top of the master cylinder. Vacuum for the brake vacuum booster assembly is obtained from the engine intake manifold. To reduce operating noise, sleeving is installed on some of the brake pipes in the engine compartment and the pipes are located in sprung pipe clips.

Scheme 5

MASTER CYLINDER

The master cylinder assembly produces hydraulic pressure to operate the brakes when the brake pedal is depressed. The assembly is attached to the front of the brake vacuum booster assembly, and comprises a cylinder containing 2 pistons in tandem. The rear piston produces pressure for the primary circuit and the front piston produces pressure for the secondary circuit. The brake fluid reservoir is located either on top of the master cylinder assembly (left hand drive vehicles) or above the master cylinder on a bracket on the bulkhead (right hand drive vehicles). The reservoir is internally divided to provide an independent supply of fluid to each brake circuit, and so prevent a single fluid leak from disabling both primary and secondary brake circuits. Should a failure occur in one circuit, the remaining circuit will still operate effectively, although brake pedal travel and vehicle braking distances will increase. If the fluid level in the reservoir is too low, the brake fluid level switch in the reservoir filler cap breaks a contact to the ABS ECU, which sends a CAN message to illuminate the brake warning lamp in the instrument pack.

When the brake pedal is pressed, the front push rod in the brake vacuum booster assembly pushes the primary piston along the cylinder bore. This produces pressure in the primary pressure chamber which, in conjunction with the primary spring, overcomes the secondary spring and simultaneously moves the secondary piston along the cylinder bore. The initial movement of the pistons, away from the piston stops, closes the primary and secondary center valves. Further movement of the pistons then pressurizes the fluid in the primary and secondary pressure chambers, and thus the brake circuits. The fluid in the chambers, behind the pistons, is unaffected by movement of the pistons and can flow unrestricted through the feed holes between the chambers and the reservoir. When the brake pedal is released, the primary and secondary springs push the pistons back down the bore of the cylinder. As the pistons contact the piston stops, the primary and secondary center valves open, which allows fluid to circulate unrestricted between the 2 hydraulic circuits and the reservoir, through the center valves, the chambers behind the pistons and the feed holes.

BRAKE FLUID LEVEL SWITCH

The Brake Fluid Level Switch (BFLS) is a Reed switch located in the brake fluid reservoir. The BFLS is connected to the ABS ECU and to ground. The BFLS is closed when the brake fluid level is above the minimum limit. If the brake fluid level decreases below the minimum limit, the BFLS opens and the ABS ECU sends a CAN message to the instrument pack to activate the brake warning lamp.

MECHANICAL BRAKE SWITCH

A mechanical brake pedal switch is used to illuminate the stop/brake lamps on the vehicle because of its high current carrying/switching capabilities. It is also used to input the status of the brake pedal to the ABS ECU. This switch is a double contact switch where the Brake Lamp Switch (BLS) contacts are open and the Brake Test Switch (BTS) contacts are closed when the brake pedal is at rest. When the pedal is depressed, the BLS contacts close and BTS contacts open, supplying 12 volts to the brake/stop lamps and indicating to the ABS ECU that the pedal has been operated. When the pedal is depressed there is a time when both the BLS and the BTS contacts are closed, which allows the ABS ECU to perform a plausibility check on the switch. A Hall effect brake pedal position sensor is installed adjacent to the mechanical brake switch. This is not used by the brake system but by other system ECU's which are not compatible with the outputs from a mechanical switch.

BRAKE VACUUM BOOSTER

The brake vacuum booster assembly provides power assistance to reduce the pedal load when braking. The assembly is attached to the front of the pedal box and comprises a circular housing containing a diaphragm, push rods, valve and filter. A push rod at the rear of the housing is connected to the brake pedal. The vacuum line is connected to a port in the front face of the housing. With the brake pedal released and the engine running, vacuum pressure is present on both sides of the diaphragm. When the brake pedal is pressed, the rear push rod moves forward and opens the valve to allow atmospheric pressure through the filter into the pedal side of the diaphragm. The pressure differential acting on the diaphragm increases the pressure being applied by the brake pedal, which is transmitted to the master cylinder via the forward push rod. If the vacuum booster fails, the hydraulic system will still function but will require greater pedal effort due to the lack of vacuum assistance.

VACUUM ENHANCER SYSTEM

Note. The vacuum enhancer solenoid valve is no longer installed on vehicles from 2003 model year onwards. On these vehicles the solenoid valve is removed, but the venturi valve and associated piping is retained. On this system the vacuum enhancement is still required, but due to the deletion of the air assist injectors, the vacuum enhancement can be permanently operated.

The vacuum enhancer system increases the relatively low vacuum available from the intake manifold to increase braking assistance. The system consists of a venturi valve, a solenoid valve and associated pipes. (Scheme 1)

The venturi valve is installed in the vacuum pipe between the brake vacuum booster and the intake manifold. An air feed pipe, from the intake duct upstream of the throttle body via the solenoid valve, is also connected to the venturi valve. Internal ducts in the venturi valve connect the brake vacuum booster and air feed ports to the intake manifold port. The duct connecting the air feed port to the intake manifold port incorporates the venturi. A check valve, integrated into the brake vacuum booster port, prevents the reverse flow of air and fuel vapor to the brake vacuum booster. The solenoid valve controls the air feed to the venturi valve. Operation of the solenoid valve is controlled by the ECM.

To improve engine idle speed refinement, when the gearbox lever is in Park or Neutral, the solenoid valve is closed and the brake vacuum booster senses the vacuum in the intake manifold via the venturi valve. When the gearbox lever is selected to positions other than Park or Neutral, the ECM energizes the solenoid valve and air from the upstream side of the throttle body is fed to the venturi valve. The air flows through the venturi valve into the intake manifold. As the air flows through the venturi in the venturi valve, it increases in velocity and decreases in pressure, resulting in an increase in the vacuum sensed by the brake vacuum booster. Depending on ambient conditions and engine speed, the vacuum enhancer system increases intake manifold vacuum by a maximum of approximately 40 percent.

PARKING BRAKE

The parking brake operates on both rear brakes via 2 parking brake cables, a cable equalizer and an intermediate rod on the parking brake lever. (Scheme 2) As the parking brake lever is applied, movement is transmitted by the intermediate rod and the cable equalizer to the two parking brake cables. Each parking brake cable pulls on a lever on the trailing brake shoe. The lever pivots against the brake adjuster rod, which forces the brake shoes apart and brings the brake linings into contact with the drum. The cables are adjusted by the parking brake adjust nut that locates the cable equalizer on the intermediate rod. A warning switch, on the base of the parking brake lever, operates the brake warning lamp in the instrument pack. When the parking brake is applied and the ignition is on, the warning switch connects a ground to the instrument pack and illuminates the brake warning lamp. In some markets, the central control unit performs a bulb check of the brake warning lamp each time the ignition is switched on.

BLEEDING BRAKE SYSTEM

Note. Following procedure covers partial bleeding of the system. Bleeding could be performed where only the primary or secondary circuit have been disturbed in isolation. It should only be necessary to bleed the disturbed system. This partial bleeding of the hydraulic system is only permissible if a brake pipe or hose has been disconnected with only minor loss of fluid.

Note. If any components upstream of brake modulator, including modulator itself are replaced. Brake system must be bled using procedure on TestBook/T4 scan tool, to ensure that all air is expelled from the new components.

BLEEDING SEQUENCE
